Let's briefly introduce this material, foamed gypsum. I believe everyone will be familiar with the bubble. It can be said that they can be seen everywhere in our daily life. In fact, foam is a kind of plastic made of resin. Because there are a large number of fixed plastics that disperse gas micropores, it has the advantages of portability, heat insulation, sound insulation and shock absorption, and has become a hot industry in plastic processing.
1. material
Foam is very easy to be damaged because of the material, so in addition to foam, some gypsum is needed to make foam rockery, which can play a simple protective role and can also be shaped.

Shaping bubbles requires skilled technology. It is very technical to carve a rugged and grotesque rockery with a knife in hand, and mistakes mean that this foam is scrapped and needs to be made again.
3. Pouring gypsum
Mainly use gypsum as a mold, and then pour the melted foam directly into the existing gypsum rockery model, so that the shape of the rockery can be displayed after the foam is cooled.
colour
Crucially, it can directly affect the fidelity of rockery, because our common foam is pure white, while natural rocks are grayish yellow, yellowish or even dark black. At the same time, we need to pay attention to the cracks, faults, cracks and even irregular weathering marks of the natural characteristics of the rock surface.
If it is temporarily indoors, gypsum is generally not needed, and it can be painted directly after the foam modeling rockery.
