Sodium carbonate is heated and the carbon dioxide goes off as a gas to yield sodium oxide.

Hi John. Just trying to get my head around this. I'm at the 5 min mark, looking at the black board, and on the 5th line, you are starting A (rutile) with 50ml of the glaze mix. However on line 1 and 3 it says 0 rutile. Are lines 5 and 6 written backwards ??? should it be pot #1 has 0 ml of the rutile glaze mix, pot #2 has 5 ml of the rutile glaze mix etc. Or am I totally missing something here :) Thank you

How do you do controlled cooling like 500 degrees per hour? I don't think my kiln has a feature like that.
@johnbrittpotteryАй бұрын
It is the kiln with digital controllers. Manuals kilns can do it if you have a pyrometer.
@balaansreАй бұрын
@johnbrittpottery Thank you, sir. Ours is a Nabertherm Top 80 electric kiln. My mind just couldn't grasp how controlled cooling like 500 degrees per hr would be possible, since our kiln doesn't have a fan or something to help cooling faster inside.

Thanks John!!! Hi from Colombia I have heard using epsom salts can damage the elements of an electric kiln… I think the amount in the final glazed pot should be very small and it doesn’t make a big damage as other salt glazes for instance … what do you think? Thank you always 🎉

Hello John, Thanks! For the first test tiles form Selsor Chun, did you take away from the original recipe colorants and opacifiers( tin oxide and RIO) before adding the new colorants? Or you added the new colorants on the original glaze including original tin and RIO? Thank you
