GongYi #4 (9.9lbs-4.5kg) Clay Graphite Crucible for Metal Melting Casting Refining Gold Silver Copper Brass Aluminum

Thank you

I bought the #4 and #6 crucibles. They arrived packaged very well in fitted foam inside cardboard boxes. They seem sturdy with thick walls. I am happy with the apparent quality and condition. I haven't fired them up yet but they came with instructions for seasoning them first. The widths and heights for both are about 1/8" smaller than the description, but that's close enough. As far as fitting tongs to them, the #6 has nearly straight vertical walls but narrows at the bottom, while the #4 noticeably tapers gradually a bit all the way to the bottom.My disappointment was that they hold smaller capacity than what was described. I filled them each to the brim with sand and then measured it. The #4 described as 490 ml holds only 400 ml of sand, while the #6 described as 710 ml holds only 575 ml. That means that the actual capacity of them is 20% less than the product descriptions show. On top of that, I had planned on filling them to 80% for safety but that means they will only safely hold maybe 60% of their described capacities. It makes me wonder if all sizes are that way. Maybe crucibles of any brand are measured this way and I'm just understanding it wrong, but now I know that I'll have to buy several sizes larger than I originally planned for my melt capacities. Other than that, I'm happy with them and plan to buy another larger one.

I melted alot cans in it an it still looks good

Melt it.

The media could not be loaded. Boyfriend bought 2 of these. He got the 5s and the 4. He uses them for melting down his cans. He melts down cans for hours at a time and these have held up for him. He will put them in the oven and preheat it to 200+ degrees before putting it in the foundry, to avoid the crucible possibly breaking. Happy with the purchase

I am very happy with my purchase, it is very versatile. Ideal tool for melting metals such as gold, silver, copper, brass, aluminum, glass, etc., well worth the purchase.
