Works great!: my feedback

Ive done 3 burns now and this is holding up very well. Better than others i have tried with that crack and become porous quickly

Pros
  • GONGYI
Cons
  • Small Capacity: With a capacity of only 25lbs or 11.5kg, the crucible is not suitable for large-scale melting or casting projects, limiting its usefulness for many professionals

very durable: my feedback

I am pleasantly surprised with the durability of this product, It has withstood multiple trips into the furnace and has completely cooled dozens of times. I have knocked it over, I even dropped it one day, still in use.

Pros
  • Well made and should last a few heatings
Cons
  • I tried to use it to melt some copper, the third time it crumbled.
