Do you leave the mould cool for at least 5 minutes? If you open it too quickly the metal is still partly soft so it will break, especially around thin areas like horses hooves or legs of soldiers. 6-Star metal has a LOT of bismuth which makes it more brittle than normal metal, so leave it cool a bit longer. Otherwise five minutes should be fine, 7 minutes to be safe. You can remove the ingates after that easily. If you let the metal cool entirely it can make trimming off ingates harder as it gets really solid. Experience helps, so you will get it right with trial and error. Also carefully bend the mould halves a little at a time to loose the figure embedded in it rather than yank the halves open.
That’s so cool, I remember making these with my brother as kids... good times
Nice.
I have almost 200 karoliner now
Where do you get the electric heater to melt the aluminium?
We don't support aluminium. Our alloys are tin and bismuth. Our solder pot goes high enough to use those metals, NOT aluminium.
Occasionally the miniature breaks when I open the mould after casting it. The metal seems very brittle. Am I opening the mould too early?

Can these moulds be used for casting pewter..??
Yes. Our 5 STar Metal is pewter so the moulds can cope with pewter.
@@princeaugustcasting Thank you, I'll order one from your website...
