Aluminium acetate is used for the mordanting of cellulose fibres such as cotton, linen and hemp. Use at 5-8% WOF.

Alum acetate is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. I recommend keeping any tools used for this process separate from kitchen tools. Alum acetate may be safely disposed of in a municipal water system by pouring down the drain.

This material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.
