Sequoia
sequoia sempervirens
Sequoia comes from Californian Coastal Redwoods. The dyestuff occurs in minute quantities in the seed cones, and only reaches useable quantities as a by-product of seed collection and reforestation programs. Sequoia yields rich purple browns when dyed at 15% WOF. Shades achieved are beautiful but with moderate lightfastness.

Mordanting: Use alum mordant at 15% WOF for protein fibres. For cellulose, first mordant with tannin at 8% WOF, then either 1) use alum at 15% with soda ash at 2% or 2) use aluminum acetate at 8%.
DYEING: Use at 15% WOF for rich purple browns. The dyestuff may be added directly to the dyebath. Add dye material to dye pot and cover with water. Bring up to about 60ºC (140ºF) and hold for an hour. Add fibres and continue cooking for another 1-2 hours.
