Note
Before the gold and silver melt, borax should be placed at the bottom of the bowl to prevent the gold and silver from melting and sticking to the bottom.
The melting bowl is easy to absorb moisture, and it is preheated and gradually heated before use to prevent water from chilling and bursting.
