Your crucible must hold molten metal efficiently without melting itself as well.
Diy ceramic crucible.
While cutting into them is dangerous i decided to do just that.
Crucibles are indispensable tools especially when you love doing projects that need metal mixing and molding.
Silicon carbide clay graphite or diy steel crucibles which type is best.
Due to some of my experiments in filling 1lb propane tanks i have some empty tanks.
To prevent your metals from being contaminated by an oxidized metal crucible you can make your own clay graphite crucible that can better withstand heat.
However when these crucibles are placed into a direct air blast usually a furnace they are prone to oxidation and will eventually fail.
Ceramic crucibles are used for science experiments and for melting down materials such as metals.
The melting of metals is a serious undertaking for the home hobby foundry worker your personal safety well being could be jeopardised if you choose to use poorly made thin walled mild steel crucibles.
Steps you must follow to cast a ceramic crucible.
Until i decide to invest in good tools i needed a cheap solution.
I decided to make a cheap diy crucible to last one or two casting sessions.
Diy metal workers like you already know the importance of a sturdy crucible in your workshop.
This is just to see if i like casting metal.
