36/60 Stoneblast® was developed specifically for the lettering of granite monuments. Packaged in 50 pound cartons (40 per full pallet). 36/60 Stoneblast® is readily available and recommended as the best product for lettering & carving monuments. Stoneblast® is made of zirconium oxide and aluminum oxide fused under carefully controlled conditions to produce a chemically inert abrasive alloy, zirconia alumina. The abrasive reduces wear on interior nozzle surfaces because it only fractures on direct impact. Stoneblast® is a register product of Saint-Gobain (formally Norton Abrasive).
Full pallet purchases are the most economical.
