Wholesale Mordants

  • Aluminum Acetate - Alum Acetate - 16 oz - Wholesale
    Quick shop

    Aluminum Acetate or Alum Acetate is a fine white powder that is refined from bauxite and purified using acetic acid to remove impurities. It is primarily used as a mordant for cellulose and bast fibers. 

    Mordant at 5-10% WOF

    Use of a dust mask is highly suggested when working with this mordant.

    Aluminum Sulfate - 16 oz - Wholesale

    $5.55

    Aluminum Sulfate is commonly used as a mordant by Natural dyers of both protein and cellulose fibers. It is used to improve both the lightfastness and washfastness as well as creating bright clear colors. Aluminum Sulfate is technically not an alum although it is commonly referred to as one.
    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. 
    • Use at 12-20% WOF

  • Calcium Carbonate - Chalk - 16 oz - Wholesale
    Quick shop

    Calcium carbonate (chalk) is a dye additive used adjust the PH of the dye bath and modify the color of natural dyes. It is particularly useful in deepening the colors of natural dyes such as Logwwod, Madder and weld. Calcium carbonate can also be used to fix natural dyes mordanted with aluminum acetate or ferrous sulfate.

    Chestnut Extract 16oz

    $40.95

    Chestnut Extract - Chestnut trees grow in many parts of the world and contain a great source of tannin. They dye a warm brown colour. This dye is also well known for it’s ability to dye silk black with the addition of logwood and an iron mordant. Dyeing: 

    Mordanting: use alum mordant at 15% WOF for both protein and cellulose fibres (there is enough tannin in chestnut so mordanting with tannin may not required).

    Dyeing: Use extract on mordanted fiber at 5-10% WOF.

    • Copper Sulfate Crystals - 16 oz - Wholesale
      Quick shop

      Copper sulfate, when used as a mordant is similar to iron in darkening the dye colors but it is less harsh on the fibers. Copper sulfate is sometimes listed as copper sulphate or copper vitriol.

      Copper sulfate can be used on all fibers and usually improves the color fastness of plant dyes.

      Copper sulfate tends to make colors greener or browner in tone.

      Cream of Tartar is the sediment produced in the process of making wine. It is an optional addition to the alum mordant bath and to some dye baths. It is used to soften wool, brighten shades, and point the color of some dyes – such as the fuchsia of cochineal to a true red. Cream of tartar works best with animal or protein fibers and is seldom used with plant or cellulose fibers. Use at 5-6% WOF

      Iron Sulfate - 16 oz - Wholesale

      $5.75

      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.

      Kamala - 16 oz - Wholesale

      $17.65

      Kamala is a powdery substance obtained from the fruit of Mallotus philippinensis, a small evergreen that is also known as the monkey-face tree (because monkeys are said to rub their faces in the fruit). Kamala is found throughout tropical India. Kamala dye is very similar in behavior and color to annatto. Kamala dyes golden yellows to tangerines with moderate lightfastness on cotton.  Lightly deeper shades are obtained on protein fibres. When iron is added deep moss green is obtained. Over or under dyed with indigo produces forest greens. 

      Mordanting: use alum mordant at 15% WOF for protein fibres. For cellulose mordant with tannin at 8% WOF and then alum at 15%, or alum acetate at 8%.

      Dyeing: Kamala is not very soluble in water, so it is necessary to extract the colourant before dyeing. To extract with alcohol, soak the powder with twice its volume of isopropyl or ethyl alcohol. Let stand for 2 hours stirring occasionally. Add the alcohol/kamala mixture to the dyebath. 

      To extract with soda ash, mix the Kamala powder with half of its weight of soda ash in twice its volume of water. Let stand  stirring occasionally. Add the entire mixture to the dyebath.  After dyeing rinse first with a vinegar solution and then thoroughly with water. Kamala dyes a beautiful orange yellow on silk and wool. It dyes lighter yellow shades on cotton.

      Oak Gall - 16 oz - Wholesale

      $41.30

      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.
