Melt the metal over the hob (Fig.1). Make sure metal is dry beforehand otherwise metal may spit and water escapes during melting.
An electric hob is preferable for better control of the heat.
Clamp molds together (Fig.2) and make sure rough sides of boards are facing into the mold.
Do not over-clamp the mold as two should be sufficient. Over-clamping can prevent the escaping of air through the mold. The quicker the air can escape the better the fill. This can often be overlooked and lead to gaps in the casting.
(Fig.3)Stir the metal with the back of a used match (just use the wooden end) before pouring the metal.
You can tell when the metal is hot enough when the match end starts to brown and produces a small amount of smoke. If the match blackens and smokes heavily, the metal is too hot and will burn the mold.
Push any slag (floating scum) away from spout of ladle you want to pour from to avoid getting the slag into the miniature body.
Tips to remember:
- Melt DRY Metal using a electric hob.
- Do not over-clamp molds. Rough sides of boards facing into mold.
- Stir with USED match to test heat. Wait until match begins to brown and releases a small amount of smoke. Do not OVERHEAT.
- Push slag away from the pouring spout.
