This dye is manufactured from the dried roots of Rheum which is a traditional natural dye from China. Chinese rhubarb natural dye powder is easy to use and dyes excellent on protein and cellulose fibers alike. 

When dyeing with rhubarb natural dye powder, you should always do so in a well ventilated space and not inhale the fumes. Rhubarb (and the rhubarb family) roots contain a lot of oxalic acid which is not good to inhale.

Create a deep golden yellow color by using hymalayan rhubarb dye powder with alum mordant. Shift pH with cream of tartar or soda ash to create more yellow or pinks and brick red colors.
Overdye rhubarb dyed fabrics with indigo for deep emerald greens.

Use at 5-10% WOF.
100 grams of Chinese rhubarb will easily dye 1 kg of fiber.

Sustainably and renewable source, fair trade supply.
