How to make antique brick carving

The antique brick carvings you are talking about are modern brick carvings, right? But in general the modern production of brick carvings whether handmade or what, are antique brick carvings. There are three main methods:

The first method is used by Xi'an Baqiao Tang Language Landscape, whose production process is described as follows: the sculptor uses clay or plaster drawings to shape the sculpture → the mold-making workshop to make molds → selected sulfur-alumina rock + high-temperature puffed shale + natural graphite + carbon fiber material + homemade improver → mold vibration vacuum → high-temperature steam curing → packaging and warehousing.

The second type is machine carving, that is, machine carving, suitable for shallow relief antique brick carving.

The third is hand-carved, carved out very much the flavor of ancient brick carving, but because the price is too expensive, often treated as a handicraft ornamental rather than used in construction.
