This should be easily reproduceble for the well equiped home hobbyist.
Remember, the glassplates are placed on top of the 2 blocks, so you can see when the sample melts.
It's not inside the blocks.
Sam, do you know what material the 2 blocks are made of? Carbon or copper or aluminum or something else?
And this thingy is meant to test melting points of SOLIDS, not fluids, to prevent any questions about that. LT/
