Fire Assaying Crucibles
Used for smelting and assaying ,excluding gold and silver elements, more accurate test results,
high temperature resistance and resistance to thermal shock . The average serial can be used
for 3-5 times of the crucibles for gold melting.
Features:
1. Long Lasting, can be used many times
2. High purity, good chemical corrosion resistance
3. Good temperature resistance, long time using at 1300°C, short time using at 1550°C
4. Good thermal shock, resistant to broken
5. High shaped density, not leaky
