Reprefentations of Coins or Medals. 439 
pends on the Goodnefs of the Wax Impref¬ 
fion or Mould, the following Rules, taught 
by Experience, are recommended to be ob- 
ferved. 
1. Let the Wax be fine, or it wants a 
proper Hardnefs, and the Impreffion 
will not be fharp. 
2. Spread it wider than the Medal, and 
of a Thicknefs in proportion to the 
Relievo of it. 
3. Clap on the Medal when the Wax has 
a moderate Degree of Heat: for, if it 
be too hot, the Medal is apt to flick: 
and, if too cold, no good Impreffion 
can be taken. The right Time feems 
to be, juft after the Wax ceafes to w T ork 
up with little Bubbles in it. 
4. Make not the Impreffion on a Table 
or any hard Body, without feveral Folds 
of Paper, or, what is better, a Woollen 
Cloth, or fome foft Leather underneath ; 
for foft Things give Way to the Preffi 
fure and Form of the Medal, which 
hard Bodies will not do. 
5. Squeeze the Medal down equally hard 
on every Side, and continue the Pref- 
fure Till the Wax is near cold : for if 
the Medal be taken off while the Wax- 
remains hot, the riling Parts, being ftill 
foft, will fink down, and the Impreffion 
be much lefs fharp.
