On varnishes or powders (635-637).
VARNISH OR POWDER .
Take cypress oil and distil it and have a large pitcher, and put
in the extract with so much water as may make it appear like amber,
and cover it tightly so that none may evaporate. And when it is
dissolved you may add in your pitcher as much of the said solution,
as shall make it liquid to your taste. And you must know that amber
is the gum of the cypress-tree.
VARNISH OR POWDER .
And since varnish powder is the resin of juniper, if you distil
juniper you can dissolve the said varnish powder in the essence,
as explained above.
