# Patina

> Patina is a working atlas of luxury fashion materials, from source to second life. It is used by a small group of
> professionals in luxury sourcing, recycling and sustainability. The tool itself is reserved to members.

## What Patina covers
- Materials: noble animal fibres (cashmere, vicuña, guanaco, alpaca, mohair, qiviut), wools, silks (mulberry, wild,
  spider, sea silk), leathers and exotic leathers, down, plant fibres, man-made cellulosics, synthetics, biomaterials.
- Sourcing basins and production statistics by country and region.
- Named actors at each stage of the value chain — breeders, processors, spinners, weavers, tanneries, ateliers,
  maisons, distributors, recyclers and resale platforms — with their documented links and group memberships.
- Industrial process sheets per step: technique, economics, finance, environment, bottlenecks.
- Certifications held and maisons' sourcing commitments; regulation (EU, France, CITES and others) with dates.
- Recycling, deadstock resale, circular initiatives, research institutions, trade fairs and events.

## Principles
