Not so much making cakes, that is just one way to relate the thoughts of glaze chemistry to something else. Same goes for John Britts explanation of the car. Not sure on a good book, digitalfire is the best website for learning glaze chemistry. Plenty of stuff there to read. You don't actually need to see any of the chemistry really, but you do need to understand maths. The '=' sign is the most important tool you have. That way you can compare things. In the glazes above I have 1 flux. In the left glaze there is 1 flux for every 2.5 everything else (all you do is add up the unity numbers) That everything else is silica and alumina. They to have a ratio to each other changing properties of a glaze. It is all about changing these ratios of everything to everything else that give you glaze chemistry. Sorry if this sounds far too complicated, I have always found maths and chemistry come naturally. -

Look at it this way, imagine you have several cake recipes and you want to compare them. One way to do that would be to reformat all the recipes so they contain just one egg, this one egg is the flux. Each recipe will have different ratios of butter and flour to that egg but every recipe will always have that one egg. You can then look at your cakes and see one with more flour to egg makes a dryer cake and more butter makes a runnier cake. Then you can get into the egg. How much of that egg is yolk, white or other. See these as all you different flux amounts but they always make up one egg. Take these glazes above, they all have the 1 egg (flux) but different flour and butter amounts to that egg (silica and alumina) -
Making myself a melt fluidity mould, always make just enough plaster... Little on the thin side at the bottom

Found 500 or so kiln bricks for sale. Don't think the seller cares how much they get, hopefully I can grab a bargain for under £100

congrats on the brick. i am on the lookout as well around here for people getting rid of them.
-
Haven't won the bid yet. If it goes over 100 it's probably not worth the 200 mile round trip.
-
Ah. Well good luck!

Anybody know how complicated it could be converting a pug mill from three phase to single phase? Found a cheap one

Being such a rubbish potter at the minute. Hardly getting into the studio at all
Need to get my lazy ass moving after work instead of relaxing.-
Me too, another health problem popped up and I have two groups of relatives coming to stay with us until Oct. 7. I guess I am just overwhelmed.
-
Sometimes I feel like quitting my day job but all advice seem to say that is the last thing you do
Hope you can recover from your health issue ASAP Denice -
Hope I recover to, I've got two more test for thyroid cancer before I know. Thank you for the kind thought.

Thermocouple chip collected and wired up with an old thermocouple. I hope this one is a type K. Can't see to find any markings.

You are becoming quite the mad scientist High Bridge!
-
It's amazing how easy the stuff works. Spent very little cash and I have a computer reading temperature from the thermocouple. Now the hard part is doing something useful with the data. If I knew how to do it you could make a 13A 240v kiln for like £200
-
I was thinking about that myself. I need a small test kiln, and it would be really neat to program it all and build it myself. Not sure if it would be worth the effort but it would be a cool project.

Great ideas everybody Keep posting them all. Going to make the next challenge thread tonight as I am stuck on night shift Sorry for the slight delay in the new challenge.

Somebody today asked me why I keep making tall drinking vessels. I said, you know me

Been on holiday in Rhodes since wednesday. Beautiful place, interesting time to be in Greece. People have no idea what is going to happen.

DIY and a kiln still at 600degC makes one sweaty potter
