The aluminum skull casting - from lost wax to solid metal

I wanted to cast a nice big aluminum skull to protect the treasure. But this is not an easy task. Watch the video to see how I came to a satisfying result.

Schöne Arbeit! Die Beulen in den Augenhöhlen stammen vermutlich von Luftblasen, die sich beim Gipsguss da verfangen haben.

[@TreasureIslandCasting]

Vielen Dank! Ich denke auch das es Luftblasen beim Gipsguss waren.

I don't know how I missed this post..... what kind of plaster was that? also since you preheated the mold, why was it bubbling when you poured it? I think the mold plaster still had moisture in it.

[@TreasureIslandCasting]

It was normal plaster. Maybe there was still some moisture in the plaster, which is pretty dangerous.
Kind regards.

How do you mix the plaster?

[@SabreCycles]

You are getting steam pockets. This is from damp mold and not heating it up to about 200F for a few hours before use. You can see this by the vibrating molted metal.

Good to know, thx. ✊🏻🖤

This is fantastic. I have wanted to try lost wax but I don’t have an oven. Your way is fantastic. Question if I may. How did you set up the foundary for this, the heat and how long. This would be a great video !! Thank you !!!!

[@TreasureIslandCasting]

I waited until the foundry has cooled down to about200degrees Celsius, then I inserted the mould with the wax inside, to melt out the wax. this takes only some minutes. After the wax is out of the mould, I dried the mould in a normal oven at about 200 degrees Celsius for several hours until there is 0% moisture inside the plaster.
Kind regards from Treasure Island!
