The Perfect Armor Improved: Water Hardened Leather

Yiguan china leather factory

Some years ago, I wrote an article on how to make hardened leather armor, using beeswax. Since then, I have concluded that although the method I described works reasonably well for SCA purposes--I have fought in my wax hardened klibanion for a good many years now--it is quite unlikely that it is the method used in period for armor.

I reached that conclusion for three reasons:

•  Beeswax is a lubricant. Furthermore, stiffening the leather makes it easier to cut, just as it is easier to slice meat if it is half frozen. So although wax hardened leather provides protection against the sort of blunt weapons we fight with, it would be of very limited usefulness against sharp swords, arrows, and the like.
• Although I have found no period descriptions of the process for hardening leather, the period term for hardened leather is "cuirboulli," which translates as "boiled (or cooked) leather." That is not the natural way of describing the wax hardening process.
•  I have found an entirely different way of hardening leather which does fit the term and which produces armor that is much better protection against real weapons. This article describes that process. As it happens, in addition to being a better guess at what was done in period, it is also a somewhat better technology for making SCA armor. 

Leather Easy Projects

Easy Projects

Making flat pieces such as lamellae or scales is easy. Because it is hard to predict the exact amount of shrinkage, you may want to first to water harden the whole piece of leather, then flatten it under a cutting board or something similar for a few minutes, then cut out your lamellae with a utility knife and add holes with a  glitter leather punch; at this stage in the process the leather can still be cut fairly easily.
If I want my lamellae slightly curved in the horizontal direction, to provide a little additional stiffness and to better fit my body, I take a cooking pot with a diameter of a foot or more, line up the lamellae around it while they are still flexible, tie them on with a strip of rag, and let them dry that way.

Making a vambrace, a rerebrace, or any other piece that is curved but not stretched--any shape you could make from a sheet of paper--is equally easy. Cut the piece of leather a little bigger than you think you need (remembering to allow for shrinkage), harden it. Wrap a towel around your forearm to protect it from heat and provide extra thickness to allow for padding (or wear your gambeson, if it covers your arm). Tie the piece of leather around your arm with strips of cloth (string will leave marks on the leather). Leave it there for fifteen minutes or so. Untie it and take it off, being careful to keep the shape--at this point the leather is still fairly flexible. Trim off any surplus. Leave it somewhere to dry. Instant vambrace.

Further Details

For SCA fighting, you should probably start with at least 8 ounce leather, which the hardening process will thicken to about 10 ounce. 12-14 ounce is better--but harder to stretch over forms. In general, you will want thicker leather over vulnerable points such as knees and elbows--which means either starting with thicker leather or leaving your leather in the hot water longer to get more shrinkage.
Sometimes something will go wrong; you pull the piece of leather intended for a bazuband out of the water only to discover that it has shrunk too much to fit your form, or that a thin section you didn't notice has shriveled up, ruining the piece. All is not lost. Flatten the piece out and cut it into lamellae. Enough mistakes and you have a free klibanian.

One minor problem with the process is that the leather gradually turns the water you are using brown. For a simple project, such as making lamellae, this may be tolerable; you can stir the piece of leather to the top of the pot every ten seconds or so to check its condition. For something more complicated, such as a bazuband or greaves, you may want to heat fresh water for each piece--which is a nuisance but makes it easier to see what you are doing.

Harder Projects

One advantage of water hardening is that when the piece comes out of the water it is stretchy--more so than leather that has been soaked for a much longer time in cold water, as described in my earlier article. This makes it possible to form pieces. You must work quickly, since the stretchiness goes away in a minute or two.
Elbow cops are easy. Start with a roughly oval shape, about 10" by 7.5", as shown in the figure. Find two bowls, diameter about 6.5", that will nest together. When the piece comes out of the hot water, put it into one of the bowls, forcing it down with your fingers to stretch the leather into the bowl, then put in the other bowl, so that the leather is being stretched between the two.
Finally, take out the inside bowl and make sure that the leather is fitting into the other with no folds, crinkles, etc.--if necessary smooth those out with your fingers. Let the leather dry. Sew or rivet on straps and you have an elbow cop. For a knee cop, do the same thing, making the piece about 14" x 7.5" and using about 7.5" diameter bowls. Details will vary according to the size of your elbow and knee and how thick your padding is going to be.

A bazuband--the Islamic forearm and elbow piece described in the previous article and shown here--is a more complicated shape. There are four ways to try to make it.

 1. Use your arm, wrapped in a towel, as the mold. This will probably work better with two people, giving you three hands to stretch leather. I have not yet tried doing the initial stretching that way, although I usually put the piece over my arm for the final adjustments.
 2. A positive form. Get something roughly the shape of the inside of the bazuband. A steel bazuband is ideal if you happen to have one lying around, but lots of other things will do. For a less precisely designed form, but one somewhat easier to obtain, use a wine bottle with relatively steep shoulders.
With a positive form, you take the leather out of the hot water and stretch it over the form. I find that it helps to tie the wrist end of the leather around the form with strips of cloth, then do the stretching at the elbow end, which is where it is most needed. then tie that down to the form with strips of cloth. This is like making an elbow cop with only one bowl, by stretching the leather over the bowl--but harder. You may find it useful to do some preliminary stretching over a rounded corner of the kitchen table, or something similar.
 3. A negative form. Get something that is roughly the shape of the outside of the bazuband and stretch the leather into it--like forming your elbow cop in the inside of a bowl.
4. Nested forms. This is the best way--once you have the forms. I've done it using a pair of steel bazubands. They don't have to be steel--once you have made a cuirboulli bazuband you are happy with, you can use it as your negative form for the next one, nested onto whatever form you used to make it.


Alternatively, you could make both positive and negative forms out of wood--by the next version of this article, I may have finished that project, using lengths of 2x4 sandwiched together and pegged. In theory, you end up with forms that can be made narrower, for thin people's arms, by removing the central piece, or wider, for big people's legs, by adding another piece.

Caring for Leather Furniture

1. Avoid seemingly harmless cleaners such as oil soap; it will stain and darken the glitter leather . Don’t use soap or detergent, no matter how mild. We can use mild soap on our skin because our skin is still alive and will replace the oils that soap washes off, but a leather sofa doesn’t have that ability. It will eventually become brittle, dry and damaged. Why not wash with soap and then apply oil? Because the oil will stain the leather. And mild soap, though gentle on dish washing hands, not only will remove the dirt but just might remove the color on the leather as well. Saddle soap may be good for that catcher’s mitt, but keep it away from leather furniture.

3.Avoid placing leather furniture in direct sunlight. Virtually nothing is safe for long in the light and heat of the sun. Avoid extreme temperatures that would cause leather to dry and crack. If you’re too cold or too hot in a room, so is the leather. Don’t place leather next to air conditioners or radiators.

4.Blot spills quickly using clean terry cloth towels or paper towels. If you spill grease or oil, use talcum powder or baking powder to help absorb it. There are also leather-furniture cleaners that would work, available from upper-end furniture stores and from some manufacturers of leather furniture.

5.If leather furniture is brand new, protect it right off the bat with a professionally applied leather protector. There are also products available for do-it-yourselfers on the after-market. If the furniture is older, have it cleaned professionally and apply the leather protector. Keep the furniture free of dust and occasionally wipe it with a barely damp cloth.

Buying Leather FurnitureⅡ

1.Look for leather upholstery with zippered seat cushions. While the leather can last decades, the seat cushion may not and you'll want easy access to get it refilled.

2.Leather takes on the temperature of your body within 12 seconds, so the notion that leather is cold is a misconception.

3. A leather sofa has to suit your lifestyle first. Is it going to work for the way you're going to use it? What room will it go in? If it's a busy space that gets a lot of wear and tear, go with a little heavier finish and protection so that you can just wipe up a stain.

4. When considering price, remember that a leather sofa will last at least as long as three fabric sofas.

5. Avoid a leather-vinyl combination. While the two materials might look good together, leather will always outlast the vinyl.

Buying Leather Furniture

Want stylish, comfortable furniture that actually improves with age? Then invest in leather, a durable and attractive material that comes in a variety of styles, colors and strengths. Here are things to keep in mind when shopping:

1. Leather is four times more durable than fabric, so don’t worry about having kids around it. Just like a leather jacket or shoes, leather furniture gets better with age.

2. Aniline leather is dyed in a drum, which allows the dye to completely soak through for a rich, deep color. No protective coating is added, and it’s the softest and most expensive leather.

3. Semi-aniline (protected aniline) leather is also dyed in a drum and has a small amount of coating applied, giving it slightly better protection against stains and fading than aniline leather.

4. For pigmented leather, color is applied to the surface, not dyed through and through. And while the color isn’t as rich, it’s finished to provide greater protection against scratches, stains and fading. These leathers are less expensive and usually aren’t as soft as dyed leathers.

5. Unlike upholstery, the color of your leather piece doesn’t make a difference when it comes to regular maintenance. Just use a damp cloth to remove dust.

How to Care for Your Leather Clothing

If your favorite way to stay warm when the weather cools down is by wrapping your fingers in  glitter leather gloves, zipping you body up in a leather jacket, and lacing up your leather boots, you also know this luxe material is intimidating to care for — until now. Here’s everything you need to know about keeping your leather clothing in tip-top shape — and cleaning up scratches and faded color after a little wear and tear (it happens

1. Protect your clothing before you wear it.

Prevention is the best form of protection, says Carolyn Forte, director of the Cleaning Lab at the Good Housekeeping Institute: “Treating leather and suede regularly helps them look their best.” Our recommendation? Try Kiwi’s Protect-All.

2. Then, reapply protection at least every three months.

Or more often if it’s a particularly nasty season (will the snow ever melt!?).

3. Select your cleaning method based on the item’s value.

While Forte says all leather is cleaned the same (more on that below) she doesn’t believe you should treat all items equally: “Smaller things are generally less expensive and easier to spot clean at home, but I wouldn’t do a jacket or pair of pants myself.” Instead, she says to take your more expensive items to a professional.

4. Take your time when going the DIY route.

With smooth leather, slow and steady wins the race. Carefully rub in mild soap or leather cleanser onto your item with a damp paper towel, let it sit several seconds, then wipe it clean. Let it air dry afterwards (away from direct heat) and use a leather conditioner to moisturize. However, at the first sign of color bleeding or fading you should stop what you’re doing and take your item to a pro.

5. And always spot-test before you start.

To make sure your cleaning products and method are a match with your leather, test it out on a hidden spot first — like inside the hand opening on a glove.

6. Don’t forget water drastically changes leather.

According to Forte, the biggest mistake people make when caring for leather clothing is getting it too wet, then rubbing the material too hard. “Leather is delicate, especially when wet and the color can come off easily,” Forte says, so don’t saturate or vigorously rub it while cleaning — and never immerse leather in water.

5 Tips: How to care for leather clothing

If a glitter leather gets wet,hang it to dry, away from heat. Putting it in a dryer or near a heating vent could cause it to shrink and lose its shape.

1. If you get a stain on a garment,don’t try to remove it yourself unless a leather-cleaning professional has advised you to. “The danger is you start removing the color and then it’s harder than ever to get out and restore,” Orlin says, noting it doesn’t matter if the piece is bright yellow, blue or a natural-looking brown. “We usually tell people who call us that we’d like to see the garment first and tell them what the alternatives are.”
2. Store leather garments on padded hangersand cover with a plain bed sheet or cloth garment bag. Avoid plastic bags, as they don’t allow the garment to “breathe,” and can promote mold and mildew. Store in a dark, dry place. Sunlight will cause fading.
3. Avoid letting a leather garment touch your skinin areas where it’s likely to come in contact with oils from your body and hair. Similarly, don’t let perfume or hairspray get on your leather apparel. They are hard to remove and the process of removing them can take color out of the clothing. “Wear a scarf,” Orlin recommends.
4. Clean leather regularly.What about those who never clean their leather jackets, believing they improve with age? “It’s sort of like not cleaning your sheets,” Orlin says. “Believe me, they get dirty.”

5 tips for styling a leather sofa

Yiguan leather,a China leather factory

1. Add some fabric.

I love leather, both in my wardrobe and in my decor. It’s durable, timeless and fancy. But the problem with leather is this: it’s not really cosy. And that’s what you eventually want from your sofa, right? An inviting place to rest at the end of a busy day. So there’s nothing like some well chosen fabric to cosy up your leather couch. Add some pillows, a throw, a nice carpet or a cow hide. Don’t be afraid to mix textures, print and colours.

2. Add some green.

There are few home dilemma’s  that  plants can’t solve, and this is no exception. A touch of green will add a splash of colour to your (probably neutral) couch. Never hurts!

3. Combine with elegant furniture.

Balance out your heavy sofa with some more elegant pieces. A table with metal legs, frames with a thin border, interesting standing lamps…

4. Consider moving your sofa away from the wall. 

If you have the space for it, and especially if it’s a larger piece, place it away from the wall. It creates a more open feeling in your room and the space will look larger, even if it’s just 20 cm from the wall. If it’s a special piece, like the sofa’s above, the space may need little more.

5. Opt for light walls

Don’t get me wrong, I totally dig luxurious, dark, eccentric spaces. But if you have a smaller house, try keeping the walls light and bright to balance the sofa.

3 Tips for Caring for a Leather Bag

When it comes to the leather pieces in our wardrobes, we aren’t always sure about the upkeep they truly require. So, when we spotted some handy tips for caring for a glitter leather bag , we made sure to take note.

1. Protect your bag: Keep the process as natural as possible by avoiding leather bags with topcoats. You want a natural patina to develop the more you use your bag. To guard against unwanted stains, try a leather protectant, which can be found at shoe repair shops, drugstores, or Amazon.
2. Give it a good cleaning once a year:It goes without saying for clothes, but keeping your bag clean goes a long way in prolonging the bag’s life. Take your bag to a leather specialist once a year to help remove dirt and germs, allowing the natural character of the leather to show through. A local cobbler can be a great resource.
3. Soften the leather by hand:Leather bags can often become buttery-soft on their own, but there is an easy way to speed up the process. Start by laying your bag on a flat surface, and begin rolling it up (starting from the bottom). Next, starting from a different side, re-roll the bag. Then, if the bag allows, you can turn it inside out and start the process again.

How to Paint Faux LeatherⅢ

Heartsun Leather  China leather factory

1 Trace a design onto the surface. Use a pencil to lightly trace your desired design onto the leather. Do not press too hard, as this will indent the leather. The paint is also semi-transparent, so any bold lines beneath the paint may show through.

2 Fill in the design. Using a paintbrush, fill in your design with the desired colors.Try to avoid creating thick layers of paint. A thick layer of paint will be more likely to crack over time. If your design has multiple colors, let each color dry before moving on to the next to avoid smudging the paint.Be sure to clean your brushes each time you select a new paint color to work with. Keep a small cup of water next to your workstation. Dip the paintbrush in the water before placing it into another color.

3 Clean up mistakes with acetone. If you make a mistake while painting, use a small amount of acetone on a cotton ball or cotton swab to gently lift away the paint. Once the paint is successfully removed and the area has dried, you can continue painting.

4 Let it dry. When you have finished painting your design, put it aside and let it air dry. The item should be secured in a safe place where it won’t be damaged or disturbed. The paint should dry within 15 to 20 minutes.

How to Paint Faux LeatherⅡ

By heartsun leather，a china leather factory

1 Clean the faux leather. Use a small amount of isopropyl alcohol to remove dust, dirt, grease, and wax from the faux leather. Dampen a cotton ball and wipe the entire surface of the material. A clean surface, free from dirt and grease, will allow the paint to strongly adhere to the faux leather.

2Use a paint palette. Prepare a paint palette so you can easily and efficiently access your desired paint colors as you work. You can buy a wooden or plastic artist’s palette at an arts and crafts store, or you can use a sheet of aluminum foil, a newspaper, or a magazine to house your paint.

3 Mix a small amount of acetone to your acrylic paint. Squeeze your desired paint colors onto your paint palette and add a few drops of acetone to the paint if you are working with acrylics. The acetone will thin the paint, making it smooth and easier to work with. Gently mix the paint and the acetone together with a small paintbrush. Be sure to only add a few drops or up to a teaspoon of acetone to your paint so that the paint does not become too watery.

4 Apply a base coat for large surfaces. If you are painting a large surface in a uniform color, you will want to apply an even base coat of paint to the surface. Use the paint you selected for your project and apply it to the surface. This is ideal if you are working with furniture or clothing.

5 Apply paint to one side of a sponge. Lightly press the sponge into the paint from your paint palette. Use long, vertical strokes to distribute the paint across the faux leather surface. Acrylic paint can dry rapidly, so you will need to work quickly if you are working with this medium. Focus on creating long strokes when painting a large surface to avoid creating streaks. If you are working on upholstery, plan to paint only one side at a time.

6 Allow the paint to dry. Before adding additional coats, the paint will need to dry completely. Place the item in a safe place where it won’t be disturbed, damaged, or moved. Wait for about 15 to 20 minutes for the coat to dry completely.

7 Enhance the color with additional layers of paint. After the first coat of paint has thoroughly dried, add another layer of paint to enhance the brightness and saturation of the color. As you add additional layers, be sure that the previous coat is dry before you apply another coating of paint.

PartⅠSelecting the Correct Paint

1Use acrylic paints. Acrylic paint can be found in a range of colors, including metallic and glittery shades, and it can be found at an arts and crafts store. It can be applied to many surfaces and it adheres well to faux leather. Acrylic paint does not fade as easily as other paints. It is also flexible, making it is less likely to crack over time.

2 Choose a leather paint. Leather paint is an acrylic-based paint that can be found at your local arts and crafts store. It comes in a wide variety of colors and is specifically formulated to adhere to both real leather and artificial leather. Leather paint is slightly more expensive than acrylic paint and can cost between $2 and $8 for a small bottle. Although it is more expensive, it is less likely to chip or fade over time.

3Select chalk-based paint. Chalk-based paint can add a shabby chic, distressed look to an accessory or a piece of furniture.It adheres to many different surfaces and fabrics, making it a great choice for painting faux leather.[5] Many brands have created variations of chalky paint which can be found at an arts and crafts store or a home improvement shop.

Skin care of the bag care techniques

    As the standard of living materials continues to increase, material requirements will also increase, and bags are essential in daily life as daily necessities as well as for women. So for your beloved leather care methods and techniques, you know how much?

(1) If there is dust on the glitter leather, you can first use a soft cloth to wipe the surface of leather dust.

(2) To the surface of the package coated with a layer of care agent, so that the leather will be the most effective care to make the package to restore the appearance of beautiful, shiny, soft, waterproof, mechanical strength (such as tensile strength, tear strength, Grain crack strength, etc.) can be increased. To better protect the surface texture of the leather bag.

(3) When natural care agent after drying, professional leather cleaning agent shaken, with a soft texture of the cloth, gently wipe.

(4) A small area of ​​pollution, direct spray cleaner on the surface of the bag. Large areas of pollution, the detergent can be poured from the bottle, installed in the container, with a soft brush stained with detergent, directly applied to the skin surface. Stay for about 2 to 5 minutes, with a soft brush to brush, to dirt off, be sure to wipe the surface texture along the skin, if the gap, to follow the gap wipe.

(5) If it is a long time stains, leather surface dirt thickness of the larger, will penetrate into the skin texture. Leather simulation leather oil, because it is oil, poor permeability, cleaning effect is not ideal, can be diluted with water by adding 10% of the water, shake and then use. Water can help skin simulation leather oil cleaner penetration, cleaning effect is good, clean and efficient, this will not hurt the bag surface, because the dermis itself has a certain moisture content, the animal itself is higher than 10% moisture content.

For the season, don't need to use the bag, you can put in a cool dry place, coated with a layer of leather protective agent, you can plug some paper filler to prevent deformation of the bag, you can place some moisture agent, insecticide in a dust bag.

How to Identify Leather Care Agent

 1. leather care agent must be grease

   

When the temperature reaches 450 ~ 750 degrees, with the help of combustible materials, can fire burning, so you can use the combustion test, that is, the use of oil, Put a small amount of care agent evenly on the toilet paper, placed in the mosquito-repellent rack, the first lit toilet paper, burn to care agent, the care agent can fire.

2.with the appropriate penetration and adhesion

    

High-quality leather care agent, can evenly penetrate the various parts of the leather inside the fiber surface, and with the intradermal fiber well together, and the wax and dermal fibers within the combination of poor, but also due to low wax burning, easy to volatile , So the wax into the leather will soon be lost, because of its loss will also take away the leather within the original oil, the leather becomes more hard, more brittle, and the wax will plug the hairy eye, so pure wax is not appropriate For the care of dermis.

3. PH value with pH detection

   

If the pH value of leather care agent PH value is greater than 7, it was alkaline, it infiltrated the skin, destruction of intradermal skin surface between the original oil film, and wash off these intradermal fat, so that the leather between the internal fiber surface Fiber bonds to each other, the friction becomes larger, but also corrosive dermal fiber, leather hardening, brittle, or even cracking - alkaline damage to the dermis is here, that is, alkaline detergent, clean leather, infiltration Dermal internal alkaline substances, will destroy the internal structure of the dermis, especially intradermal fiber surface of the oil film, so that leather harden, brittle, and even cracking. Therefore, in addition to skin simulated leather oil cleanser, the skin care can not use detergent.

Leather care agent qualified pH = 5 ~ 7 between. PH value of the test paper in the general chemical teaching store for sale.
