Elm-Leaved Sumach (Rhus coriaria)
|Common Name||Latin Name||Plant Family|
The leaves and bark are rich in tannin. The leaves can be collected as they fall in the autumn and used as a brown dye or as a mordant. The fruit and bark are also used. The leaves contain 20 – 35% tannin and yield a yellow dye.
The finely ground leaves and stems provide the dyeing and tanning agent ‘sumac'. The shoots are cut down annually, near to the root, for this purpose. A fawn colour, bordering on green, is obtained and this can be improved with the judicious use of mordants. The cultivar ‘Mesculino’ is very rich in tannin, containing up to 35%[46, 61].
An oil is extracted from the seeds. It attains a tallow-like consistency on standing and is used to make candles. These burn brilliantly, though they emit a pungent smoke.
A black dye is obtained from the fruit[4, 14].
A yellow and a red dye are obtained from the bark.
