Ho know whenyour Glass is well annealed.
Take so many pieces of glass, asyou purpose to lay
beds of glass in your Oven or Furnace, and draw in
colours what you will upon the said pieces, or if you
wipe them over with some colour , with your finger
only it is enough: and lay with every bed os your
wrought and drawn glass, one of the said pieces of
glass, which are called watches, and when you think
that they are sufficiently annealed with a pair of pliers
or tongs, take out of the first watch, which is the low-
est, and next to the fire, and lay it upon a board untill
ic be cold: then scrape it good and hard with a knife,
and if the colour goeth off, ic hath not enough os the
fire, and if it hold, it is well annealed.
When you would^occupy any oyled colour in Glass,
you (hall once grind it with gum w ater, and then tem-
per it with Spanish Turpentine, and let it dry as near
the fire as may be, then ic is pe-rfest.
