its fire a little azure colour.
To imitate this fine colour, take four ounces of the matter,
prepared with natural cryftal and faturnus glorificatus ; two
ounces of crocus martis prepared, one ounce of verdigreafe, two
ounces of mercury calcined ad rubedinem, and two ounces offal
gem ; reduce all to fine powder, mix them together, put them
into a crucible, cover it, lute it, and fet it in a glafs-houfe fur-
nace for three days ; then take it out, and fet it into the fur-
nace, where glafies are fet to anneal, there to colour by degrees
for twelve hours; then break the crucible, and you will find the
matter tinged of a fine Ruby colour, which you may divide, cut,
To make the lalajfe Ruby. This fpecies of Ruby is of a very
bright colour, refembling a vermilion, rofe, and crimfon, being
mixed of a natural red and of a fky colour. To imitate it,

cryftal, half an ounce of crocus martis, half an ounce of mercu-
ry calcined ad rubedinem, two drachms of fal gem ; the whole
