Casting

CASTING

This technique uses forms made of calcium sulfate (gypsum) or silicone between two ceramic molds.

The cheapest metals to cast are lead, tin, and pewter. Today's pewter contains no lead and is an alloy of tin, copper, bismuth and antimony. This alloy is called Britannia metal (92% tin, 6% antimony, 2% copper).

The metals melt in a cast iron pot over a gas flame and pour into two part ceramic molds.

Bronze was used instead of copper in casting fake due to the fact that it's melting temperature of about 180 C lower than that of copper.

Casting fake cards made in open forms, thus casting shells are formed only on the back (top) side of the fakes.

Counterfeiting that has not cast sinks due to the fact that its production was used by low-melting-point metal (probably lead-tin alloy).
