Then you can use a worm drive saw that's been modified to water cool the blade. Or have a helper use pump up type sprayer to apply water to the blade. Then you can use a straight edge to run the saw against. You'd get a much better cut and wouldn't have the dust mess. If you use water make sure the saw is plugged into a GFCI receptacle.

Horticultural sand is very gritty sand made from substances such as crushed granite, quartz, or sandstone. Horticultural sand for plants is often known as sharp sand, coarse sand, or quartz sand. Usually when used for plants, sand consists of both large and small particles.
High purity silica of four nines with minimal mineral contaminants was obtained through our proposed low-energy method. The initial acid leaching of the diatomite resulted in a silica precipitate with lower contents of Ca, Mg and Fe materials. The final washing of silica slurry led to a silica product with lower Na and Fe contents. Incorporation of mannitol in the final acid washing stage ...
