WonderFil

WonderFil is IMD’s popular flint, produced by wet grinding silica sand with flint pebbles in ball mills and passing through ferro filters. Selected silica sand with a SiO2 content of over 99% is used as raw material. Quality is strictly controlled in residue on 325 mesh and particle size distribution. Wonderfil is the right quality ground quartz for rapid glazes and porcelain body production.
