Sil-O-Spar is a high quality blend of sodium/potassium/calcium aluminum silicate (feldspar) and silica, ground to 170 mesh, for ceramic applications. Carefully beneficiated and controlled for quality, Sil-O-Spar provides the advantages of pre-blended and uniformly sized non-plastic flux with low iron oxide content. Its coarse particle size makes it an ideal choice for casting slips.
