Burgundy 🤤 thanks John!

Thank You.

[@mattmurray778]

Brilliant as always! Very informative, i would have put the email in the description below. I would love to see this same set, but subtracting tin to each, and see the spectrum from red to green

[@johnbrittpottery]

You need to run that test and show us.

[@EarthNationCeramics]

Are all of these glazes no hold? Straight up to Cone 6 and free fall?

[@johnbrittpottery]

Yes, E1 cycle

Thank you very much for that. May I ask you about the numbers, do they mean percentages or some other kind of measurement? Take the raspberry, for example, is 0.80 CaO 80% or is it something else? Thanks.

[@Cate7451]

Yes it does mean percentage, if you don't mind me replying, typically glaze recipes show the percentage of each of the main materials so that it adds up to 100. So like 20% calcium, 20% flint, 20% feldspar and so forth to form your base recipe and then the colorants so maybe 2% cobalt. So your recipe would then add up to 102%. I usually write out my recipe with a dividing line between the two.

[@johnbrittpottery]

It is 0.8 moles in the UMF. Look the recipe up on Glazy.org and you will see the analysis and see 0.8

[@Cate7451]

vena thunderbird okay it's ablaze made by a well known potter. It's like alchemy. When I show people that I add a pinch of green to white and make fustian it's like magic. Take care. This is an apropos lesson as I am doing something that produces a lovely maroon. Looks amazing. But where is it coming from. Hmmm. Just unloaded an awesome kiln load. I impressed myself. Had a lot of trouble with my kiln. But potters just keep on going. I wonder what John means by his reply to this thread? Pottery chemistry is fun. I will look up your recipe in a bit here. Take care.

@@johnbrittpottery Thank you very much for your reply, Mr Britt. I knew it would be mols when I asked, hahah, as I'm more familiar with the percentage approach. I'll have to apply myself and study some chemistry. In the meantime, 1,000 samples for tomorrow. XD
