Cultured marble is polymer resin mixed with marble dust or other whitening agent such as calcium carbonate.

Calcium carbonate cultured marble.

If you re casting a figure with fine detail too much additive will prevent the resin from filling all the small voids in the mold. Ground calcium carbonate is the primary ingredient in cultured marble applications. The grinding process is controlled to create a distribution of particles that is most beneficial for cultured marble production. One of the largest applications for calcium carbonate fillers is in the manufacture of synthetic or as the industry prefers to call it cultured marble.

It comes ready to use with the proper combination of coarse and fine particles. Marblemite is a calcium carbonate filler specifically designed for use in cultured marble. Cultured marble is a polymer composite product made with calcium carbonate and polyester resin which is well suited for bathroom applications.

Calcium carbonate is a chemical compound with the formula ca co 3 it is a common substance found in rocks as the minerals calcite and aragonite most notably as limestone which is a type of sedimentary rock consisting mainly of calcite and is the main component of pearls and the shells of marine organisms snails and eggs calcium carbonate is the active ingredient in agricultural lime and. The carbonate filler levels used here are quite high ranging from 300 to 400 phr. The mixture is cast in a mold coated with specially formulated gel to produce a tough durable and lustrous surface.
