MAKING of PLASTERWARE PRODUCTS

The manufacturing of stone-cast products for indoor use starts with choosing the right type of stone plasters for the particular product requirements and how it is to be decorated.

There are some stone plasters that will produce a better smoother tougher working surface especially if these pieces are going to be highly decorated. Otherwise, you could find yourself using a lot of decorating material trying to stabilize a porous surface. Some stones are better for developing an antiquing finish.

Because these stones are extremely strong, and hard, less water is used to mix them. Usually, the working ratio of water to stone is 1 to 3. Remember, the more water used in mixing these stones, the weaker the product.

Having the right ratio of stone to water is very important, along with the correct soaking time, mixing time, and resting time before the plaster mix is poured. When the stone has reached a creamy consistency, slowly pour the mix into the lowest corner of the rubber mold. The stone normally sets in 35 to 40 minutes, and de-molding may occur any time later.

If de-molding early, use care and caution when working with the newly cast pieces as they will be quite tender and soft. Dry slowly and evenly to prevent the product from effervescing.
