Before starting it
is always advisable to heat the mold and use it while
warmed.
This removes dampness, which can
cause the hot metal to splatter and to allow a better
flow of metal in the mold.
The temperature may vary depending
on the mold and metal used but I find that between
30 degrees and 40 degrees Celsius best. You can easily
set the temperature in most ovens.
Always apply dry talcum power (see
illustration on right) to BOTH parts of the molds
from edge to edge. This protects the mould. More importantly
this practice allows the air to escape during casting.
Talcum powser needs to be absolutely
dry before application so warm it as well as the mold.
(Water expands 2000 times when turned to steam.)
Always slap mold halves together
to remove excess talcum powder. (See illustration
on left)
To much can effect the surface texture
of the miniature or block the flow of metal to some
parts of the miniature.
Place O Rings in the neck location
(does not apply to all moulds).
This will form a tubular joint for
the location of the head and will allow you to do
simple alterations as changing the head or turning
the head (only applys to certain molds).
Tips to remember:
- Heat mold and talcum beforehand.
- Apply talcum evenly and clap
halves together to remove excess.
- Add O Rings to body to allow
later alterations.
