On the Meltability of Alumite

The meltability of alumite is related to all things. In the industry of smelting and casting, the former people attached great importance to its characteristics. For alumite, the number of its meltability must be investigated by the worker.

When the watcher is melting and casting, the alumite is put in, and the control of the heat is related to the melting degree. If the melting degree is unknown, the alumite is difficult to melt, or it is uneven, resulting in flaws in the casting.

To know the melting degree of alumite, it is necessary to observe its quality and identify its origin. Differences are produced, and the melting degree may vary. And the melting degree is also affected by other substances, such as the addition of adjuvants, or the increase or decrease of its melting

The good work of ancient times, in the study of the melting degree of alum stone, much depends on experience. Experiment and trial to obtain accurate numbers. Although today's skills are new, the melting degree of alum stone must not be ignored. The essence of the utensils and the strength of the things depend on this. Therefore, the melting degree of alum stone is the foundation of the foundry industry and cannot be ignored.
