Alum, Aluminum Triformate, Copper Sulfate & Ferrous Sulfate

A practical starter kit for natural dyeing, botanical printing, eco printing, bundle dyeing, and color exploration.

This kit brings together four essential mordants and color modifiers used by natural dyers. Mordants help natural dyes attach more strongly to the fiber, improve wash and light fastness, and allow you to create a wider range of shades from the same dye bath.

With alum or aluminum triformate as your main mordant, and copper and iron as post-dye modifiers, this small kit opens up a beautiful world of natural color: brighter yellows, deeper greens, rich browns, soft olives, grays, antique tones, and more muted historical shades.

What is included

100 g Alum
A classic mordant for wool, silk, and other protein fibers. Alum helps create clear, bright natural dye colors.

100 g Aluminum Triformate
A practical and easy-to-use mordant suitable for both protein and cellulose fibers. A good choice for dyers who want a simpler mordanting process.

100 g Copper Sulfate
A powerful color modifier. Copper can deepen yellows, shift colors toward green, enrich browns, and create more antique, earthy tones.

100 g Ferrous Sulfate
Also known as iron. Iron is used in very small amounts to sadden, darken, and shift colors. It can turn yellows olive, tannins gray or black, and bright colors into softer, more muted shades.

Each kit comes in a small cardboard box and includes an A4 instruction leaflet with basic WOF percentages and beginner-friendly usage notes.
