熔解皿 — 熔融石英陶瓷坩堝，550公克，4吋，金銀銅鑄造用

The 550g capacity is spot on—I consolidated a full jar of scrap silver in one go and the 4-inch dish held it all without spillage. The fused silica surface stayed smooth even after a hot pour, so cleanup was just a quick tap.

I was skeptical a dish this size could stay stable with a full 550g charge, but the fused silica handles the heat beautifully and the 4-inch surface gives plenty of room to stir without spillage. My scrap silver melted evenly with no cracking, even after repeated use.

It handles the big jobs without a fuss—I consolidated about half a kilo of scrap silver and it didn’t even come close to overflowing. The 4-inch size is just right for a serious batch, though it does take a bit longer to heat through than my smaller dish.
