I would suppose that the manufacturer would provide details as to what the melting point of the crucible is....and it probably isn't a good idea to find for yourself. Anyhow for sure you can melt gallium. https://en.wikipedia.org/wiki/Gallium

But it probably cannot melt tungsten. https://en.wikipedia.org/wiki/Tungsten
