Hi Dave,
There was (is?) evidently great use made of the berries and bark of
various species of buckthorn for the purposes of dying. I found the
following (and many other references as well):
"Dyer's Buckthorn (R. tinctoria) is used, together with the Asian
Chinese Buckthorn (R. utilis), to produce the dye "china green".
Another species, Avignon Buckthorn (R. saxatilis) provides the yellow
dye Persian berry, made from the berries." - Wikipedia
"(Rhamnus cathartica) Dyes were also sourced from the alder
buckthorn, and a yellow dye was produced from the bark, while the
unripe alder berries were used in the production of a green dye -
these dyes were utilized in various manufactures." - Herbs2000.com
"(Rhamnus frangula) The bark and leaves of the Alder Buckthorn yield
a yellow dye much used in Russia; when mixed with salts of iron it
turns black. The berries, when unripe, afford a good green colour,
readily taken by woollen stuffs; when ripe, they give various shades
of blue and grey. After removal of the bark from the stem and
branches, the wood of this shrub is used for making charcoal,
yielding a very light, inflammable kind, and being on that account
preferred to that of almost any other tree by gunpowder makers, who
name it 'Black Dogwood.' In Germany, for the same reason, it is
called Pulverholz ('powder-wood')." - Herbs2000.com
"From the dried berries, a series of rich but fugitive colours is
obtained; the berries used to be sold under the name of 'French
berries' and imported with those of Rhamnus infectorius from the
Levant. If gathered before ripe, the berries furnish a yellow dye,
used formerly for staining maps or paper. When ripe, if mixed with
gum-arabic and limewater, they form the pigment 'Sap or bladder
green,' so well known to water-colour painters. The bark also affords
a yellow dye." - Botanical.com
Cheers,
Chris
