How to Make a Sodium Silicate Solution

Sodium silicate, also known as "liquid glass," as a versatile and widely used solution. Sodium silicate is known as liquid glass for good reason: When the water it is dissolved in evaporates away, the sodium silicate bonds into a solid sheet of glass. Heat tempering makes the silicate patch harder, but the solution can still be used for fireproofing wood and stain-proofing concrete if applied and allowed to dry at room temperature.

Things You'll Need

• 1 pint (16 oz.) sodium silicate powder

Instructions

1. • 1

     Bring purified water to a low simmer (approximately 175 degrees) on an electric stove.

   • 2

     Stir sodium silicate powder into hot water with a long-handled metal spoon. Continue stirring until the powder is completely dissolved.

   • 3

     Remove solution from heat and allow it to cool to room temperature. Stir solution every five minutes.

   • 4

     Pour solution into a plastic container as soon as the solution cools, and seal it up.
