How much alum do you use to dye?
Thereof, how do you dye alum?
Place the alum and cream of tartar in a cup, add some boiling water, and stir to dissolve. Add the alum and cream of tartar mixture to a dye pot full of enough water to cover your fiber, and stir. To the dye pot, add the previously soaked fiber you wish to mordant. Place your dye pot on a burner.
Likewise, how do you mordant fabric with alum? Soak your silk fiber in water for at least 1 hour. Put the alum and the cream of tartar in a cup, add some hot water, and stir to dissolve. Add the mordant mixture to a bucket of lukewarm water, and stir. Put the wetted silk fabric into the mordant bath, and gently move it around in the bath for a few minutes.
Considering this, how do you mordant?
The technique is simple: measure the mordant, dissolve in water, and add to a dye pot or bucket or tub filled with water. Add the fibers and hold them for a period of time, then remove and proceed to the dye bath.
Do you need to mordant silk?
Use 25% alum or 8% aluminium acetate per weight of dry silk. I prefer to use alum for pure silk and for wool/silk blends. However, for cotton/silk blends as well as hemp/silk blends, aluminium acetate is better. If you are dyeing the silk with woad or indigo, you do not need to mordant the silk first.
