which we have equally employed. It is this : make enamel

the cramps.
The teeth moulded thus, need not undergo the operation
of hardening ; they are then put in a porcelain furnace, with-
out having previously undergone a preparatory baking.
In the mean while, having spoken of the processes in the
manipulation of divers pastes, and of enamels to suit them,
as well as the manner of modelling the teeth, we believe it
will be useful to give here the formulas proposed by M.
Delabarre, in order to present, in the same compass, all that
belongs to the confection of incorruptible teeth, and let every
