Product Description Fused quartz bowls,melting dish Model No.Appro.capacity in mlSize in mmYN-00215Ф56*H20YN-00528Ф79*H36YN-01070Ф88*H36YN-01590Ф99*H36YN-020128Ф108*H44YN-030175Ф118*H49YN-050330Ф140*H54YN-100450Ф172*H63YN-200740Ф220*H70 Selecting fused quartz as the main raw material, processed by modern ceramic technology, mainly used for the melting of gold,platinum, dental alloys, and other high-temperature alloys.SiO2:>99.0%,Content of impurities (K2O, Na2O, Fe2O3) < 0.10%,High strengthCompressive strength at room temperature ≥70MPa,Withstand high temperature of 2800C and limit of 3000C.Features: high temperature resistance, room temperature pressure resistance, strong thermal shock resistance,corrosion resistance,long service life.Note:Fused Quartz Bowl is easy to absorb moisture during transportation. Dry it with low temperature before use. In order to prolong its service life, please preheat a large area before heating at high temperature and gradually increase the temperature. Then sprinkle some borax on the bottom of the bowl and overfire. After the borax is melted, a layer of thin film crystals will be formed on the bottom of the bowl to prevent the gold and silver from sticking to the bottom of the bowl after melting.Application: dedicated refractory bowls such as leather tiger wind balls, gold melting machines.
