Iron Sulfate (Ferrous Sulfate) - Sulfate de fer
Iron Sulfate (Ferrous sulfate) can also be called "Green Vitriol" and is used as a mordant in wood to accentuate the color of vegetal stains and dyes. Color-Rare's Iron Sulfate is sold as water-soluble crystals. Iron sulfate can also be used to set vegetable pigments in many other applications. Iron Sulfate is also used to whiten wood to a gray colour (to give it an 'aged' appearance).
Iron Sulfate also doubles as a tool in the garden to destroy moss or to add an iron supplement to certain trees or plants.
Product Origin: France
How to use Iron Sulfate:
Dissolve 60 to 80 g of Iron Sulfate in 1 liter of water. This will create a mixture that is a greenish colour. One coat of Iron Sulfate solution applied to a very tannin wood (like Oak, Walnut, Mahogany and Cherry) will create a silver gray to a blue steel color when it has dried. Wood, such as maple, beech, birch or cedar, will have a less pronounced color due to the low level of natural tannin.
Iron Sulfate is a very strong mordant, so a little goes a long way and the color results can be dramatic!
