nobox is a true mad scientist, relatively unknown in his time, but will be remembered as the greatest maker of... alarmingly dangerous contraptions that ever lived, after he is inevitably killed in an explosion.

Foundry and moisture are a explosive!

[@meettheworld6241]

I wonder if you mixed some Portland cement into the mold material and some silica if it would be more heat resistant

[@Iraqi1995-3]

Can I know what is this mud powder or sand or calcium is it glass water and thank you ❤

[@davegeorge7094]

Bad time to heat the garage in this weather lately. haha

[@sunfishensunfishen2271]

Is the water glass pure or is there a bit of water in it? I’d like to do some casting and they’ve got jugs of this stuff on Amazon at varying purities

Your zirconia additive SHOULD be able to handle at least 3200 f when calcined, so as a surface coating, it should be fine, provided you fire it properly over the right length of time at the right temperatures for proper calcination.

LOOK at that freezing vapor at jet outlet!

[@Iraqi1995-3]

Hello how are you brother can you give me a mixture of a substance that can withstand heat in this Video
And is the material of casting sodium silicate metal with dust

Brass fittings are pricey, like what you did here!!

[@zumbazumba1]

Anyone knows how to make coloidal sodium silicate with citric acid?
