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.❤

I recommend one of those magnetic stirrer.

Yo this is art!

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)

Hey Rudy, this is a very good point of yours. I use this kind of "waterglass" in one of my videos to make "activator" for making geopolymer and although it has the very same composition (calculated via stochiometry) as my sodium silicate plus NaOH activator for the same metakaolin, it performs differently. Its only logic as waterglass is produced by melting together SiO2 plus an Na2O deliverer, as we would say in my are. Of course it is not the same as dissolve SiO2 in NaOH solution. Anyways, thanks for your video Ogmios Forge!

Nice :O

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

I’ve since found another brand that has WAY less of the blue bits, enough to just pick out :)

Seems like this is a dangerous method. Any tips on how to eliminate danger?

Just use silicagels without humidity indicators. They are colorless.

@@Rohit-oz1or The best way to avoid danger is to just stay inside away from everyone and everything. But a slightly riskier approach would be to just buy it.

​@@Rohit-oz1or there's no way to eliminate danger when sodium hydroxide is involved, just minimize it by wearing gloves and eye protection.

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

I believe that’s the exact same stuff. Can anyone else confirm?

Yes it just takes longer to dissolve so it’s best to grind it up first. Also make sure the dry packets you use are pure silica as some of them have other things in them. Hope this helps.
