Pros
- They work great for copper
Cons
- You will only get one mold. The picture shows you gets more and the description can be misleading.

Description of GONGYI High-Purity Graphite Ingot Molds Crucible For Melting, Casting, And Refining Metals - Ideal For Copper, Gold, Silver, Aluminum, And Brass - Size #5 (3Kg, 170Ml, 5.75Fl. Oz)
Specification: For 3250g Gold / 1530g Silver; Inner 125 x 60 x 30 mm (7.6 fl oz). Selected Material: Graphite ingot molds are made from high density fine grain graphite, 99.95% Graphite. Ash content less than 0.1%. Better for Refining than Silicon Carbide Graphite Crucibles. Well-made: The smooth cavity finish of the graphite ingot mold makes the ingot very easy to remove without sticking to the mold itself. Wide Application: The graphite ingot mold receives liquid metal of precious metals and other types of metals, such as gold, silver, metal, aluminum, copper, brass, zinc and so on, and conserves them until they are solidified. Extremely Durable: Great alkali resistance and corrosion, super acid and impact resistance.
Pros
- Works just like it should. Graphite dust does make it easier though.
Cons
- The Size #5 (3Kg, 170Ml, 5.75Fl. Oz) of this product is not enough for large scale melting or casting, and you may need to refill or use multiple molds
