The combined application of brain tissue and smoke produces soft and pliable buckskin leather, with a dark honey color. This treatment differs from the traditional tanning methods used in other societies and cultures and is thought to be preferable to vegetable tanning methods where tannins are exclusively used. [1]
Tanning, or hide tanning, is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed. Historically, vegetable based tanning used tannin, an acidic chemical compound derived from the bark of certain trees, in the production of leather. An alternative method, developed in the ...
A large number of different tanning methods and materials can be used; the choice is ultimately dependent on the end application of the leather. The most commonly used tanning material is chromium, which leaves the leather, once tanned, a pale blue colour. This product is commonly called “wet blue”.
The words "tannin", "tanning", "tan," and "tawny" are derived from the Medieval Latin tannare, "to convert into leather." Bark mills are horse- or oxen-driven or water-powered edge mills [ 2 ] and were used in earlier times to shred the tanbark to derive tannins for the leather industry.
Following Pullover, the company created a more mainstream programme, FoxTales, adapting a number of classic Eastern European folk tales to a cast of animal characters, narrated by Grandpa Fox (again Peter Davison). The show was well received but suffered from the fact that budgets for children's programming were being cut as imported animated ...
The oldest confirmed leather tanning tools were found in ancient Sumer and date to approximately 5000 BCE. [5] The oldest surviving piece of leather footwear is the Areni-1 shoe that was made in Armenia around 3500 BCE. Another, possibly older, piece of leather was found in Guitarrero Cave in northern Peru, dating to the Archaic period. [2]: 340
Sun tanning or tanning is the process whereby skin color is darkened or tanned. It is most often a result of exposure to ultraviolet (UV) radiation from sunlight or from artificial sources, such as a tanning lamp found in indoor tanning beds.
It can cost 3 to 5 times more per lamp to use electronic ballasts than traditional choke ballasts, which is why choke ballasts are still used in the majority of new tanning systems. Another disadvantage of the older style choke ballast is they are designed for European electricity, and require incoming voltage in the range of 220 V AC and 230 V AC.
