Applications
Sodium Silicate, also called waterglass, has a very wide range of applicaitons, including an adhesive or binder, especially in high temperature environemnts, it is a major component of most exhaust repair puttys.
Treating cardboard tubes – Sodium silicate can be used with calcium chloride to treat cardboard mortars using the method in this link.
Preserving eggs – Sodium silicate (waterglass) solutions are used to preserve fresh eggs by sealing the pores in the shell, keeping bacteria out and water in. Water glass should be diluted to 10% concentration (1 litre of 75Tw will make up 3.6 litres of 10% solution). Half fill the container with the 10% waterglass and then add eggs. 3.6 litres of 10% solution will be enough to preserve about 200 eggs.
