Yea, well, I still don't understand this, except how to follow a recipe. But all this Unity stuff is hieroglyphics. 

 

 

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)

You obviously have a great deal of chemical knowledge and making cakes. hehe, just kidding. But I don't think this is going to be easy to learn. Can you give me a book reference that I can sit down and learn at a slow pace.  I really appreciate your help, but I may need some time. I want to look at the diagrams above and see what you see. And I know this might take time, but I ain't dead yet, but I am retired. Thanks for the lesson. Oh, btw, I only eat vegan cake, no egg, butter or milk. LOL. Thanks.

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.

I have Digitalfire. I guess I just need to read and then try things out. I was good at math, but not so much chemistry. (Many moons ago). So I'll just have to brush up on all this. It does look challenging. And that = fun.

Thanks for your help.
