Prefered methods of the native peoples in the northern parts of the world; The Saami in northern Europe, the Chukchee in NE Russia, the Eskimo and Inuit along the northern tier of North America, who all make relatively soft 'bark tanned' leathers. Apears to be Alder bark. Though i have heard of the Saami using Birch bark as well.
In some tanning processes, yes. But not in others. One very old process for tanning leather used layers of leather and animal dung, it was allowed to ferment for months. That used bacteria and fungi, but nobody knew it when the process was developed.
Sycamore trees are used in various industries and applications. The wood is commonly used in furniture making, flooring, and musical instruments. The bark is used in tanning and dyeing processes. Sycamore trees are also planted for landscaping and shade due to their large size and attractive appearance.
Natural resources used to make a pair of shoes include leather from animals, rubber from rubber trees, cotton for some components, and various metals and minerals for elements like eyelets and buckles. These resources go through processes such as tanning, rubber harvesting, and mining to be transformed into shoe components.
Bacteria is used in the pre-tanning processes ,i.e, soaking, dehairing, bating and degreasing. And most important it produces proteolytic enzymes known as proteases which are extracted and used in dehairing, soaking and bating processes which is required to produce leather.
One natural material that grows on trees is rubber, which is harvested from the latex of rubber trees (Hevea brasiliensis). This latex is collected by making incisions in the bark, allowing the milky substance to flow out and be collected. Rubber is then processed and used in a variety of products, including tires, footwear, and various industrial applications. Another example is cork, which is harvested from the bark of cork oak trees without harming the tree itself.

Tannin is a polyphenolic compound found in various plants, but it is most commonly associated with oak trees, particularly species like Quercus robur and Quercus alba. Tannins are present in the bark, leaves, and acorns of these trees. They also occur in other sources, such as chestnut, hemlock, and certain fruits, contributing to their astringent taste. Tannins are widely used in the tanning of leather and in the production of wine.
Nope, they used bark from the mulberry trees
Yes, leather is opaque. It is a thick material that does not allow light to pass through it. This is due to the dense fibers and tanning process used to create leather.
The most commonly used solvent for leather tanning is water. Various chemical agents, such as chromium salts or vegetable tannins, are added to the water to transform raw animal hides into durable leather. These chemicals help stabilize the collagen fibers in the hide, making it resistant to decay and giving it the desired characteristics of leather.
