Durable Molds
These work great for making aluminum bars. The bars can be a little difficult to remove, but I have used these molds quite a bit and they are still holding together well.

works great but graphite dust gets on everything
the graphite dust gets EVERYWHERE when trying to handle but i don't think that's super avoidable, just something to keep in mind when buying a graphite mold

Preheat?
I've seen few reviews about these cracking after a few pours. I'm new to this, but I'm wondering if users are preheating before pouring. That seems like it may be a reason for the cracking/breaking. I consider these "consumables" and will need to be discarded or crushed into graphite powder at some point. I'm just not sure what's considered a reasonable amount of "consuming".The picture with the copper bar is after about 5-6 pours and it seems to be working fine for me. However, I'm not sure what the expectation should be. Likewise, I'm not sure what the expectation is for the price point. Seems to be a decent price for what I've found out there.Explanation on the mold with the broken corner: It was my first pour for aluminum. I did 2 copper bars and they came right out just fine. They basically slipped out. However, when I went to dump out the aluminum, they didn't want to come out. One came out after a few taps. The one in the mold with the broken corner was being really stubborn and I got a bit rough trying to get it to release. Well, the picture shows what happened. I've done aluminum pours since and I think it was because I didn't let the first ones cool long enough.One other thing I should mention: These are listed as 1 kg molds. That may be true for gold or silver (I don't know). However with copper, when filled, will net about half a kilo (or a little over a pound). Even less for aluminum. Not a complaint. Just something to keep in mind if you're not already aware of that fact.Overall, I'm fine with them. I'll use the one with the broken corner for any remaining copper left over after I fill any other molds I have or get. I can always remelt it another time.
