The ferrous indigo vat (aka iron vat) is a great vat for dyeing cellulose fibers like linen and cotton with deep lasting blues. We do not advice dying silks and wool in the ferrous vat, because it could leave those fibres brittle.


The sturdy box comes with all the ingredients you need for a ferrous indigo vat,  including elaborate printed instructions on how to set up, maintain and dye.

The vat you prepare will be enough for about a kilo of fabric in a medium shade of blue.





Ferrous Sulfate

Calx (lime)
