    Oak Gall - 8 oz

    $21.60

    Gallnut or Oak Gall is used to mordant cellulose fibers and fabrics before the alum mordant is used. Alum does not combine as readily with cellulose fibers as it does with protein fibers.

    Tannin has a great affinity with cellulose fiber and once mordanted with tannin, alum combines well with the tannin-fiber complex.

    Gallnuts from the oak tree are the earliest and richest source for natural tannin. They are produced by insects who deposit their eggs in small punctures they make on young branches. As a protection, the tree excretes a tannin rich substance that hardens and forms into a gallnut. These are collected and ground for use as a tannin mordant.

    Gallnuts are used in the leather tanning industry, and for in some medicines.

    Use at 6-8% WOF.

    Soda Ash - Sodium Carbonate - Washing Soda - Soda Glass - Soda Ash Fixer

    Fiber reactive dyes used on cellulose fibers needs to be "fixed" to the fiber. Soda ash is a mild alkali that allows this reaction to occur. Enough soda ash should be used to get a PH of around 10.5 or all the dye will not adhere to the fiber.

    Care should be used when using on silk as too much may damage the fabric.

    Soda ash is also suitable for use as a ceramic Glaze, Glass making, toothpaste, water softener, washing soda and tie dye.

    Iron Sulfate - 1 oz

    Iron can be used as a modifier or a mordant. It can be used on all fibers and makes colors darker in tone. It also increases lightfastness and washfastness of the dyed project. 

    This iron powder is light green and food grade. Too much iron can harshen the hand of protein (silk, wool) fibers, so use sparingly.

    iron Sulfate may also be used as the reducing agent in a traditional indigo fermentation vat, often called the “Copperas” vat. 

    It is also possible to create an iron acetate mordant by combining iron and acetic acid. 

    Keep out of reach of children.

    Potassium Alum - 16 oz

    $14.40

    Potassium Aluminum Sulfate is probably the most commonly used mordant by Natural dyers of both protein and cellulose fibers. I is used to improve both the lightfastness and washfastness as well as creating bright clear colors. It is safe when handled properly and relatively inexpensive.

    Aluminum sulfate results from the refining of Bauxite which is raw aluminum ore. Sulfuric acid is used during the process to remove most of the impurities such as iron and silica. Potassium Alum is created by further purification with potassium. This results in fewer impurities, especially iron and results in brighter colors. Potassium alum is more expensive but preferred by many natural dyers.
