What to consider before buying

Choose a crucible based on your temperature range, chemical compatibility, and budget. Alumina offers a good balance, porcelain is budget-friendly, platinum for trace analysis, nickel for alkaline fusions, graphite for high-temp combustion, borosilicate glass for low-temp work, and quartz for high-purity needs. Always match the material to your specific application to avoid contamination or damage.
