Usage Tips

• Pre-dry before first use: Quartz crucibles can absorb moisture during storage or transport. Before your first use, dry it at a low temperature — for example, bake it in an oven at approximately 150°C for around 30 minutes.
• Gradual temperature increase: To extend the service life of your crucible, preheat it over a wide area before applying high heat, then gradually increase the temperature to avoid thermal shock.
