Jul 25, 2019· Heat 4 to 8 grams of sodium hydroxide in 10 milliliters of water. Once the sodium hydroxide is dissolved, slowly add 6 grams of crushed silica gel beads. Heat the solution between additions. If the crushed beads won't dissolve, add a little more water to the solution. You now have sodium silicate or water glass.
Oct 18, 2017· Preparation of concentrated sodium silicate stock solution. My particular method for making concentrated sodium silicate is a little different from others. My aim is to use as little water as possible so that the finished solution is concentrated (thick and goooopy without leftover silica gel crystals or a crusty insoluble scum.
The use of sodium silicate as a wood preservative may not be common, but it was hardly dreamed up in 2005. I am in the process of using an old method at home that uses sodium silicate solution as a wood sealer/fireproofing which is then sprayed with a boric acid solution which keeps the bugs at bay and forces the sodium silicate to gel.
