Classification of fibers
If we want sustainable and beautiful results, we need to understand our fibers
Aluminum and earth crust
What elements and what compounds can we use in order to stay eco-friendly?
Lecture: Chemistry of mordanting process
There are two basic strategies. Eastern strategy is respecting affinity, and Western (european) strategy is creating affinity.
Lecture: home-made Aluminum acetate
Michel explains the chemistry of the very important process: how do we prepare Al acetate for mordanting.
Demo: 3 ways to prepare Al acetate
Michel shows 3 method of preparation of this best mordant for cellulose fibers (and eventually for silk).
Preparation of iron acetate. Combination of aluminum and iron mordanting.
This demo is important for all dyers, but it is crucial for ecoprinters.
Classifications of tannins
We would need tannin for many purposes, let's understand the chemistry of tannins...
Double mordanting with aluminum and tannin
This technique is almost magical, although it is based on scientific approach. It suits not for every fiber and not for every dye.
