Oh I'm so excited about this episode! I've been curious about adding glass to my pottery! Watching now!

[@sarahg5113]

Would it be possible to mix the glass powder with the glaze and paint it on? To try to get it to melt down the inside of the bowl

[@maxspruit8370]

I think the reason the glass is "crazed" or broken, is because its thermal exlansion coëfficient is higher. The melting point of silica is lowered with sodium/Na or potassium/K, that is the most common glass we know. But heat resistant glass that is not tempered (labratory glass) is made with a borium/B addition.
Borium glass has way lower expansion when heated. Which is why is fire proof/resistant to uneven heating.
Try Borium glass for less crazed an chippy glaze.

I ground the glass up into a power and add some in my ash glaze

Why so much talking and not action? Is not what the title of the video suggests…
