Marblemite is a calcium carbonate filler specifically designed for use in cultured marble.  It comes ready to use with the proper combination of coarse and fine particles. The grinding process is controlled to create a distribution of particles that is most beneficial for cultured marble production.
    What is different about Marblemite?  Marblemite is not merely a repeat of one-bag fillers that have been tried before, and it is not a blend like some other one-bag products on the market today.  Marblemite is crushed and ground directly to the correct distribution of particles for maximum effectiveness in cultured marble recipes.  Since it is not a blended product, there is no danger of having the wrong blend shipped to you.
  Marblemite produces parts with a popular warm tone. This allows for greater flexibility in final color than "marble dusts" with a cold gray tone.  In addition, the high whiteness of Marblemite may allow reduced levels of costly color pigments offering additional raw material savings.
