Calcium Acetate

Calcium acetate may be used to make an aluminum acetate mordant. It is an alternative to sodium acetate. 

Homemade Aluminum Acetate Solution
An aluminum acetate solution can be made from calcium acetate and potassium aluminum sulfate. Depending on the availability of these materials in your area, this can be cost effective.

To make enough aluminum acetate solution to mordant 1 kilo of fabric, combine in 3 litres of hot tap water:

150g sodium acetate or calcium acetate
150g potassium aluminum sulfate

See our Mordanting instructions for more information.

 This mordant can be used on its own or in combination with tannin. Calcium Acetate can also be used as a buffer to control the acidity of a dye bath.
