Where to Buy cheapest crushed shell gravel?

 Where to Buy cheapest crushed shell gravel? The shell mold is a mold formed by the hardening of the sand mixture on a hot metal model. To make the shell mold, the metal model (usually made of aluminum or gray cast iron) is usually heated to about 260-150 degrees Celsius.

The sand mixture (usually silica sand or shingles) is then applied to the hot surface with a heat-resistant resin adhesive.

Due to the heat of the model, the adhesive of the sand mixture is activated and causes the fine sand particles to stick together and to the surface of the metal model.

After the mold hardens, it is removed from the model surface. In this way, a sand mold is made in the form of a shell with almost thin walls, in which the shape of the model is created.
