Works well for making bronze which is at the limits of its melting temp.Only downside is it takes roughly 2 hours to reach 1100C meaning you get one bronze pour per 3 hour operating cycle. however gold and silver melt at lower temperatures than copper alloys which is what this is really designed for.I’ve done 10+ 3kg melts working on a bronze project. If I didn’t use the crucible as a slow cool mold to eliminate pour porosity it likely would of lasted 20-30 melts.The crucibles themselves are sturdy with good lifespan but are limited just like any other. Graphite is pure carbon meaning it slowly burns away as it’s used and is prone to cracking under impact.
