However, it's important to select quality silica sand that is properly washed and graded for pool filtration. Industry best practice is to use #20 Silica Sand which is greater than 95% silica and guarantees an effective grain size of 0.45 to 0.55 millimetres, trapping particles with diameters between 20 and 80 microns (the human eye can see down to 50 or 60 …
Soda Ash is used in the manufacture of sodium compounds like borax. ... (soda-lime glass) is made by melting such mixtures of sodium carbonate, calcium carbonate, and silica sand (silicon dioxide (SiO2)). When these materials are heated, the carbonates release carbon dioxide. In this way, sodium carbonate is a source of sodium oxide.

Flux can be used for seasoning crucibles, keeping materials liquefied for easier pouring, and for removing impurities when refining your metals. Some of our individual flux components include: Anhydrous Borax, Boric Acid, Assay Dense Soda Ash, Assay Silica, Fluorspar, Potassium Carbonate, Manganese Dioxide, and more.
Pic 2 is litharge and silica sand. Pic 3 is soda ash and silica flour. Pic 4 is soda ash and silica sand. However, a consideration of the relative melting points gave a possible answer to why the other samples did not fuse into good slags. Litharge has a melting point of 888 o C, the lead silicate had a theoretical melting point of 766 o C.
