Graphite metal casting mould for a single sided East India Company ingot. (real pirate treasure) The ingot produced by this mould is 90mmx40mm with a maximum thickness of 20mm. This mould will require sufficient pre-heating to prevent cracking from thermal shock. Please ensure it is heated thoroughly. (Ideally close to the temperature of the melting point of the metal being poured into it). The ingot in the picture is an example not included with the purchase of the mould (sorry). Thank you for looking and happy casting! p.s. If you would like a specific design that I do not have listed then please message me!
