instead of fine turpentine. And you can put into two
lbs of toucommon turpentine one lb
of fine turpentine oil & do as with the other one. This one
will cost you no more than five or six sols per
lb & is sold for 40 sols per
lb.

This vessel is used to make large quantities of
turpentine oil, that is to say a bucket an
hour. And no matter which turpentine it may be,
whether fine or coarse. One needs to give, as you know, a little
fire at the beginning. And always keep cold water in the cooler
on the top. The lb is sold at xii sols, &
at the bottom of the vessel remains the colophony, known
as pix graeca. In this vessel, eau de
vie is also made well and there is no need to distill it again. You
do not need a oven for this copper vessel, but
only charcoal around it if it has a flat bottom, but if it is
round, you will place it on a trivet.


@ It is better to heat the varnish a little bit, rather than to
put it out in the sun, because this makes the panel
warp.


@ Some say it is not good to distil in this copper
vessel because it is made green. However, when tinned, it is
good.


For varnishing

Turpentine varnish does not need any glue because it
is fat and viscous and it is not absorbed in the wood like that
of spike lavender and sandarac. Also, that of spike
lavender does not require any glue on iron &
similar materials that do not absorb, but on wood and on colors
which havedo not havegum or colle
de destrempe, it is necessary to lay one coat of the said
colle de retailles & to let it dry & to
varnish.
