How to apply horn oil on vegetable tanned leather? (cow foot oil)

Question: When I first entered the leather goods pit, I applied horn oil to the leather surface. I used a sheep ball brush (it’s called this...) but there is a very embarrassing problem, that is, if the entire leather surface cannot be painted at once, the color of the leather will be different shades as the application time goes on... and it will also appear. Sometimes the paint is heavy and sometimes light... I painted a piece of light-colored vegetable tanned leather to look like a patterned plywood... I am very worried...

LLL ZZZ: First of all, it should be called [Neats foot oil], English Neats foot oil, beef leg Oil boiled from bones. Different oils have different degrees of waxiness and how quickly they oxidize. Fatty acids will change color after oxidation. So generally speaking, mink oil has the most wax content, cows foot oil is basically pure oil, and horse oil contains a small amount of wax. Generally, the oil will be absorbed into the leather, causing it to soften. The wax will remain on the surface, making the leather surface smooth and bright. You see why cows foot oil comes in barrels and mink oil comes in small cans. In fact, cows foot oil is used in large quantities in tanneries. It is used to brush the entire leather with a brush. It is used purely for replenishing oil in large quantities. In addition, you can actually use some vegetable oil, such as coconut oil, which at least tastes better. . . If you want a new piece of leather to turn into a very old one immediately, its very simple. Just soak it in water, apply a certain amount of any oil, and then when its semi-dry, polish the surface with something smooth. It can quickly polish the surface pores. Cao Jiaojiao: I use woolen sheepskin to oil it, rub it in circles, and then spread the oil evenly on small parts of my hand, just like wiping my own face. Just be patient and wait, it will become even. Plato: As everyone said before, it will be better after it is done. In addition, I don’t know what your technique is. Generally, the oil will be more evenly applied in a circle instead of parallel. Personally, I think wool balls are difficult to use, and it might be better to use cloth or sponge. Thats probably it. Pi Chen'er: Give me some other suggestions. First of all, we need to understand why we apply horn oil? What is horn oil mainly used for? What will happen if you apply horn oil to your skin? I think the main use of horn oil is to replenish fat after leather carving is dyed. There are also many people who apply horn oil before making raw vegetable tanned leather. This is to prevent stains, but I think there are better things to prevent stains. There are also people who use leather products for fat replenishment after the leather surface is slightly dry and cracked due to the loss of lipids after using it for a period of time. I also think there is something better. There are also peopleIn order to speed up the effect of raising cattle, I use horn oil on leather goods, but after applying it, the leather goods that are raised will turn black.

I use Knight brand 100% horn oil. 1) Unscrew the lid, there will be a layer of tinfoil sealed inside, usually don’t tear it open, use a toothpick to poke a few holes; 2) Use clean white cotton cloth, some people will use cotton balls, but it is not very easy, because the contact area is too small 3) A very important technique for applying horn oil is to apply it in small amounts multiple times. Take a small amount of horn oil each time and apply it evenly on the leather surface; 4) Exposing the skin to the sun is also a very important step. , which allows the horn oil to penetrate into the leather. Of course, it cannot be exposed to direct sunlight. Just put it by the window. If the effect still does not meet the desired requirements after a few days, you can apply horn oil again and then nourish. Leather Uplay: Nowadays, there are actually fewer and fewer people in the circle who still use cow’s foot oil to oil vegetable-tanned leather. Everyone basically uses a bristle brush + mink oil to oil the leather surface. There are two points worth noting if the cows foot oil needs to be applied evenly. First, if conditions permit, choose some thinner cows foot oil. Second, after oiling, it needs to sit for a longer time, about a day, to allow the oil to slowly penetrate and spread in the fibers. But I still recommend that you use a bristle brush + mink oil to brush the leather surface back and forth to oil the leather, which is both uniform and convenient.
