Ferrous Sulphate (Iron)
$7.50 - $13.50
Iron mordant for natural dyeing.
Ferrous Sulphate is usually used to change the colour of a dye. It changes shades to deeper, darker shades and is better used in a premordant bath than directly into the dyebath. It also makes natural dyes more lightfast and washfast.
More often used with cellulose fibres than protein fibres as it can make protein fibres brittle and harsh.
Use at a maximum of 2% to 4 % Weight of Fabric.
