Since 1980 I have used Dharma Fiber Reactive Dyes for cotton and sometimes
for silk, and Dupont silk dyes for silkpainting and Rozome on silk. I
also use your Silkpaint gutta, though I am primarily a wax-resist
artist.
I began learning batik in 1980, and soon after that began silk painting.
I love Dupont dyes, and used them for many years in a slightly diluted
form for silkpainting. Then in 1999 I began learning Rozome with Betsy
Sterling Benjamin, and find that the undiluted Dupont is a reasonable
substitute in rozome for the very concentrated Japanese dyes. Lately I
have been experimenting with soy wax to replace paraffin, since it
washes out. Perhaps Dharma would be interested in carrying it? Also have
bought many brushes, auxiliary chemicals, and other silkpainting tools
from Dharma over the years. There is always a big order from Dharma for
my silkpainting, batik, and rozome students at Ghost Ranch in NM.
