Ferrous Sulphate

Ferrous sulphate, more commonly known as iron, is used as a natural dye modifier, darkening (or 'saddening') natural dyes. It also can act as a mordant, to improve light and wash fastness for dyes,<br><br>Ferrous sulphate is considered toxic, keep away from children and pets, work in a ventilated area and wear a mask and gloves whilst handling this powder. I recommend keeping any tools used for this process separate from kitchen tools. <br><br>This material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.<br>

Aluminium Triformate

Aluminium Triformate is a room temperature mordant for both cellulose and protein fibres. part of the alum family, it is a more recent addition of mordanting options for the natural dyer, gaining popularity (particularly with wool dyers due to its temperature requirements) for its low-impact process (water & energy saving). It produces similar results to that of alum acetate, and can be used with a pre-tannin bath to help improve dye fastness. use at 5-10% WOF.<br> <br>Alum Triformate is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. I recommend keeping any tools used for this process separate from kitchen tools. Alum Triformate may be safely disposed of in a municipal water system by pouring down the drain.<br><br>this material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.<br><br>

Symplocos

Symplocos is a natural, plant based mordant. The leaves are a natural bioaccumulator of aluminium, and when harvested and groundintoo powder, these made an effective mordant. it can be used on both cellulose and protein fibres at 50% WOF.<br><br>Note that Symplocos does impart a yellowish shade onto your fabrics, and will therefore affect your final dye colour.<br> <br>Symplocos is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder.

Aluminium Sulphate

Aluminium Sulphate is used for dyeing protein fibres such as wool and silk. it can be used at 10-15% WOF (weight of fibre). cream of tartar can be used in addition to this mordanting process to assist with the bond of the mordant. it can also be used to mordant cellulose fibres in addition to a tannin bath. <br> <br><br>Alum sulphate is considered non-toxic, but working in a ventilated area and wearing a mask and gloves is best practice whilst handling this powder. We recommend keeping any tools used for this process separate from kitchen tools. Alum may be safely disposed of in small amounts via a municipal water system by pouring down the drain.<br><br>This material comes in a natural biodegradable cellophane. We recommend transferring this to a glass or plastic jar for long-term storage.
