Tips for using quartz bowls
Quartz bowls are prone to moisture absorption during transportation. Before use, please dry the water at low temperature. To extend its service life, please preheat a large area before heating at high temperature and gradually increase the temperature. Then sprinkle some borax at the bottom of the bowl over heat. After the borax is melted, a thin film of crystals will form at the bottom of the bowl to prevent gold and silver from melting and sticking to the bottom of the bowl.

100g and 200g both refer to the amount of gold that can be filled in a bowl at once (for example, a 100g quartz bowl can hold 100g of gold). If silver or other metals are loaded, they need to be converted according to different metal densities
