How to use muffle furnace program temperature control to determine tea ash content?

The ash content is not the ash of tea leaves. Ash is the residual inorganic matter after tea leaves are burned at high temperature. Inorganic substances refer to all substances that do not contain carbon atoms and carbon atom bonds. The total ash content of tea mainly refers to the inorganic substances after the tea has been burned at high temperature, which generally accounts for 3.5% to 7.0% of the total dry matter of the tea. The total ash content of tea is relatively high, so ash content is an important indicator for judging the quality of tea.
