Accurately speaking, medical gypsum can't be used for sculpture, because it dries too fast, and it is hard to carve after drying. You should be talking about turnover, right Sculptures are generally made of relatively soft and easy-to-process materials such as clay, net-bound soil and carved oil sludge, which is convenient for continuous modification. After the sculpture is completed, if you want to preserve it for a long time or copy it many times, you need to use silicone as a mold to copy it. After the mold is completed, you can copy the prototype. At this time, resin and gypsum can be used as copying materials. Ordinary gypsum 10 costs more than 25kg per bag, which is poor after curing. Medical gypsum is expensive and hard after curing. It's your choice. If you copy goods in large quantities, I suggest you consider using resin!

Hope to adopt! ! !
