Alum Instructions

GENERAL INFORMATION AND USE

Alum is used in the fabric marbling process as a pre-mordant to make marbling paints "stick", and is also used as one of the safer chemicals to pre-mordant fabric in preparation for natural dyeing.

DIRECTIONS FOR USE

Dissolve 2 teaspoons alum into 1 gallon of water to make a solution for fabric to be marbled. Dissolve 2 teaspoons alum in 1 quart of water to make a solution for paper to be marbled.

ADDITIONAL USES:

Also used in natural dyeing.

DHARMA COMMENTS:

ALERT: Be careful not to leave on the fabric too long or get hot as that combination can really damage the fabric.

This product is Aluminum Sulfate (AS) wo Potassium. Most dye books including Wild Color as referred by a rep. at Dharma recommends Aluminum Potassium Sulfate (APS) also known as alum. While it's OK to use AS it is recommended that smaller amounts be used. Also colors may appear dull compared to those used with APS. To learn more go to www.earthues.comaboutmordants.html
