Lavender Grey compared to Logwood
"Steel Blue" Grey (top right)
Called “green vitriol” in old dye books, this is an essential of the dyer’s art. Iron after baths can take any yellow or gold and turn it to a soft green. Reds become burgundies, pinks become plums, and any tannin source (any weed or bark) can be used to make pretty greys, just by adding iron.
Usually used as an after-mordant modifier, where you just watch the colour and when it has changed “to taste”, rinse it. If used as a pre-mordant, ½ oz per pound is the usual ration = 3%. Do not use too much as it can “weight” and damage delicate fibres.
Ferrous sulphate is commonly ingested as an iron supplement, but Cheryl recommends that ferrous gluconate or ferrous picolinate be used instead. Do not drink your iron mordant! However, it is safe enough to be used without gloves, tho we always recommend the habit of wearing gloves when doing dyework.
