What is the old mold made by Changge Porcelain Factory?

The old mold made by Changge Porcelain Factory is brick mold. In the sixties and seventies of last century, square and long adobe was used for building houses in rural areas, which was the mold for producing rectangular adobe at that time. Wood structure, with tiny cracks at the bottom, can produce three bricks at a time. With the development of society, it has already faded out of people's sight, so it has certain collection value.
