In Australia, the dye supplier Batik Oetoro sells sodium silicate solution under the name Drimafix. Batik Oetoro is now located two hours to the north of Sydney, but they also sell their products by mail-order. Certain portions of their website are impossible to navigate in many web browsers (silly popups prevent the links from being clickable), so go directly to their page of chemicals, where you can find Drimafix listed.
We make sodium silicate from drain cleaner and those little gel beads you find packaged with electronic items for humidity control.
The procedure is really simple, just make a solution of 10mL with 4-8grams of sodium hydroxide, use the full 8 grams if you want stoichiometric sodium silicate, and 4 grams if you want “liquid glass” solution for doing the chemical garden experiments.
Heat the solution and add in 6 grams worth of crushed silica gel beads. The finer the better. if they aren’t dissolving, you might need to add more water.
Once it’s dissolved, you’ll have a concentrated solution of sodium silicate.

“Magic Rocks are a classic chemistry project that doesn’t take a lot of time to complete.”
Magic Rocks are a classic chemistry project that doesn’t take a lot of time to complete. Sodium silicate is the chemical that provides the ‘magic’.
You can prepare sodium silicate or water glass from gel beads (silica) and drain cleaner (sodium hydroxide). Sodium silicate can be used to make chemical gardens, like those that result from Magic Rocks (which you can make yourself).
Sodium Silicate Materials
All you need to make a sodium silicate solution are water, silica, and sodium hydroxide. Silica comes in those little packets labelled ‘do not eat’ with electronics, shoes, etc. Sodium hydroxide is readily available in its pure form or can be found as drain cleaner.
6 g silica gel beads (crushed)
4-8 g sodium hydroxide (4 g for water glass, used in the magic rock project, or 8 g for the stoichiometric ratio for sodium silicate)
10 ml water
Prepare Sodium Silicate
Wear proper safety gear, which includes gloves.
Heat 4-8 grams of sodium hydroxide in 10 ml of water.
Once the sodium hydroxide is dissolved, slowly add the 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.
That’s it! You now have sodium silicate or water glass. NurdRage has a YouTube video of this procedure, if you’re interested in seeing how it’s done.
