is the primary nontoxic mordant used to fix Earthues natural dye extracts to protein fibers such as wool, silk, alpaca and mohair. Alum has been used since the time of the Egyptians and Earthues alum is refined to remove impurities and to yield clear colors.
Aluminum Acetate 8oz for $20
is used for mordanting cellulose and bast fibers and is a fine white powder.
Calcium Carbonate 4oz for $4
also referred to as chalk, this white powdery mineral is a common addition to the madder dye bath to deepen shades and is one of the principle minerals that create hard water.

also known as potassium bitartrate, is a sediment that is produced in fermenting grape juice. It is an optional addition to the dye or mordant bath, and is used to acidify the dye bath to effect a color change, and to soften wool fibers. It will dramatically shift the color of cochineal, madder and lac from their fuchsia and burgundy red shades to a brighter, redder shade. With madder, it will shift the hue to orange. It can inhibit the color development in logwoods and certain tannins, so it is rarely used with these dyes.

Orvus 8oz for $9
Orvus Paste was first used as equine and livestock soap, but quilters and other fiber artists use it as a mild, synthetic soap for textiles. It is pH neutral. We use it as part of our wool scouring process, and to wash dyed fibers.
pH Indicator Strips - Box of 100 $30
These strips are used to measure the pH of a dyebath or indigo vat. The range is from 0-14. Box of 100 strips.
Scour 4oz for $3
Earthues Cellulose Scour - is designed for use with cellulose fibers and as part of the Silkzorb degumming process. It works on cellulose and bast fibers in combination with soda ash and heat and thoroughly cleans cellulose fibers, removing excess wax and other materials which could inhibit the takeup of dye.
Silkzorb Degummer 2.5 oz for $7.50
a liquid enzyme that remove excess sericin in silk fibers, allowing for a deeper penetration of dye and deeper shades. Use with a small amount of soda ash and Earthues Cellulose Scour.
Soda Ash 4oz for $3
