Glossary of terms

Rostaing Tannery - Since 1789
Denomination applicable to leather that has retained its original flower, the colour of which is obtained by dyeing in the bath and not covered by another top coat.
Chrome tanned calf leather. Its appearance is smooth. It is used in leather goods and high-end footwear.
The leather crust comes from the splitting of thick leather into two “leaves”, one containing the flower called “leather” and the other made of the flesh of the leather called “crust”. The “Velvet” crust has an external fibrous appearance. The “pigmented” or “coated” crust is covered with a thick coating that gives it the appearance of smooth leather. In furniture as in leather goods, the use of the crust must be mentioned because it is not entitled to the designation “leather”.
Processed product of an animal skin by means of tanning or impregnation preserving the natural structure of the fibres and having retained all or part of its flower.
Leather with visible surface grain.
Tanned skin with an irregular and dark marbled appearance. Its oil quantity exceeds the average by 15%. It is therefore a highly nourished leather (usually in a fuller’s drum) and because of its heaviness mainly used for footwear and sometimes clothing.
