Put the specified amount of water into the mixing container and add the plaster powder over the course of one minute, scattering it around. After adding the plaster powder, let it sit for one minute. 2. Stir with a stirring rod for three minutes at a speed of about 100 revolutions per minute. Better results can be achieved by using an electric stirrer to mix evenly. Be careful not to stir too much, as this will result in a lot of floating water. 3. The plaster will heat up and finish setting within 35 minutes. However, since the expansion rate changes while the heat generation temperature is high, wait until the temperature has cooled down to room temperature before removing the mold.
