Saving some money on materials, by mixing up my own sodium silicate (i.e. “water glass”) from drain cleaner and cat litter (yes, seriously). Full disclosre: almost no fire in this video :(

Thanks for the video! Your stainless steel vessel did not discolour!

Add sand and NaOH to a ball mill like a rock tumbler and add ceramic balls and let mill for a couple days. Next pack into a steel container and heat till it melts, adding some extra hydroxide helps. When its molten pour it out on a cookie sheet and disolve in basic distilled water ph over 12. The sodium silicste will disolve and the junk sinks. Store in a dark plastic bottle.❤

Great video. What do you use for clean up of pots and jug?

Face shield and eyepro. You absolutely do not want the sodium hydroxide powder or solution in your eyes. That said I'm going to give this a shot

But you didn't use it to make a sand core. 🙁 How do we know if it really works? There are different sodium silicate formulations and some are said to not work as well as those sold for foundry use. Have you used your solution to make cores, and how did it turn out? (Rudy in Winnipeg)

That lovely blue color comes from cobalt chloride which is a toxic chemical. Take care man!

Can silica gel (used for absorbing moisture in packaging), be used in place of cat litter
