bhunt7 Posted June 22, 2015 Report Share Posted June 22, 2015 Ok, here's a question for you techies. In entering a failed glaze test into the seger calc. It breaks down each chemical. I've read people can adjust the glaze using these calculations. How? How do I know what to adjust? I've heard it said you don't have to be a chemist to make glazes. Not sure that's true. What is the balance? where I can go to figure out how to balance glazes using the formulas? I hope this question makes sense. Ty Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted June 22, 2015 Report Share Posted June 22, 2015 google digital fire and use a program called insight. thousands of pages of explanations of things and they have software that you can try out that explains each chemistry and what each glaze ingredient has in it. It seems daunting at first but just keep reading and studying. Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted June 22, 2015 Report Share Posted June 22, 2015 Why did the glaze test 'fail'? The formula splits glazes into three parts, Fluxes, Stabilizers, and Glass Formers, aka RO/R2O, R2O3, RO2. Example: Flux: CaO :1 Glass Former: SiO2 : 3.5 Stabilizers: Al2O3 :0.4 Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted June 22, 2015 Report Share Posted June 22, 2015 +1 for Digitalfire.com. They have video tutorials on how to use insight that you can access for free. It gives some good rudimentary information on how to fix certain common glaze issues. They're a little long (20 min) but you get a better understanding of how things work. How exactly did your glaze fail? Link to comment Share on other sites More sharing options...
bhunt7 Posted June 22, 2015 Author Report Share Posted June 22, 2015 All, thanks for resource. Actually, I haven't made a glaze yet but in my readings it refers to the seger, which I've checked out online, but all those formulas and numbers are Greek to me. I'll do some reading and studying on insight and see if it gets thru this hard head. Th =) Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted June 22, 2015 Report Share Posted June 22, 2015 It really isn't that confusing once you understand what highbridge was explaining above. It is just getting a balance for a solid glaze that looks how you wanted it to do does what you want that is the hard part. Link to comment Share on other sites More sharing options...
bhunt7 Posted June 22, 2015 Author Report Share Posted June 22, 2015 Thanks grype..I guess I just want to understand what in the seger tells me something is "off". I suppose I'll figure it out once I start mixing glazes. I'll let y'all know for sure how it goes. Will be interesting. 😄 Link to comment Share on other sites More sharing options...
