A wax melter is a container that is used to melt wax. It is sort of like a big pot, but instead of cooking food, you put wax inside and heat it up. The wax melter has a heat source, which can be electric or fueled by gas or oil, that warms up the bottom of the container. As the wax heats up, it becomes liquid and runs to the bottom of the wax melter where it can be easily poured or drawn off into molds or containers for use.
Wax melters are used by people who make things with wax, like candles or soaps. They make it easier to melt the wax without having to use a stove or other heat source that may not be safe. Wax melters can come in different sizes and shapes, with some big enough to hold multiple gallons of wax, while others are smaller and designed for personal use.
It's important to be careful around wax melters since they can get very hot, and the wax can be dangerous if it gets on your skin. Always follow the instructions carefully and make sure to use protective gear like gloves or aprons when handling the melted wax.
