Pomegranate - An extract or a powder from the rinds of pomegranates Punica granatum, this dyestuff is high in tannin and improves the light and washfastness of any dye with which it is mixed. In India and south east Asia it is used as both a dye and a mordant. Pomegranate yields soft yellows to green-yellows when used at 5-8% WOF for the extract (15 - 20% WOF for the powder) for a medium depth of shade. When combined with iron, pomegranate yields yummy warm cement greys and deep moss greens. It is often mixed with the more fugitive turmeric dye to brighten the yellow and make it lightfast.
Mordanting: use alum mordant at 15% WOF for protein fibres and cellulose fibres (there is enough tannin in the pomegranate so mordanting with tannin is not required).
Dyeing: for either the powder or the extract, add to hot water, ensure it is thoroughly mixed and then add the fibre. Simmer for about 1 hour. If a darker colour is required leave in dyebath overnight.

Gallnut Extract 100g (3.6 oz.)
$14.95
Visit product page →Gallnut is the earliest and richest source for natural colourless tannin and is found in the gallnuts of oak trees. They are produced by insects who deposit their eggs in small punctures they make on young branches. The tree excretes a tannin rich substance that hardens to form a gallnut. These are collected and ground for use as a tannin mordant for cellulose fibres, in the leather tanning industry, and for medicine. This extract is a rich source of gallic acid. Mordant using 6%-8% WOF
Tannin is used as part of the mordant process for cellulose fibres and fabrics. Alum does not bond as well with cellulose fibres as it does with protein fibres. Tannin bonds well with cellulose. and once treated with tannin, alum will combine with the tannin-fibre complex. Many dyestuffs contain tannin (black oak, pomegranate, quebracho, fustic, etc) and do not need an additional tannin. The two most popular tannins in the Maiwa studio are oak gall and myrobalan.
Tannins can be clear or they can add colour to the fibre, and this is an important consideration when selecting a tannin.
• Clear Tannins: “Gallic” - Gallnut, Tara, some Sumacs
• Yellow Tannins: “Ellegic” – Myrobalan, Pomegranate,
• Red-Brown Tannins: “Catechic” – Cutch, Quebracho, Tea leaves, and some Sumacs.
