Keeping Record of your work Part III The ternary plots of Flux, Amphoteric and Glass formers.
Posted 11 January 2013 - 05:56 AM
The reading of this kind of plot requires a bit of reflection but once figured out, it again adds interesting information on the glaze(s).
The capability to predict the glaze appearance is somewhat less accurate than with the Al/Si plots, especially when Bore is used in the formulation. On the other hand I find that from scientific/technical viewpoint it helps to understand glaze chemistry.
What you need is molar % of the used elements. If you have a recipe, you can calculate this by hand but, this is rather tedious. A glaze software like INSIGHT can give it in 1 or 2 clicks. Then the different Mol% of the metals are grouped in Fluxes, Amphoterics and Glass formers. When % are calculated for each group, these values can be entered in the ternary plot template.
The template to make ternary plots is rather complex. I can provide it on request.
An example is at the end of the text.
In the example, WWW172 is likely to be a matt glaze, WWW390 has to rated as satin-matt and the other 2 glazes are probably glossy.
Next time I will discuss the relative importance of limit values for the common elements used in glazes.
We are still quite far away of 'putting things together ', be patient! In a few more posts to come, it will be revealed.

Edit...I think I get it.
I assume you have found out how it works. Just follow the tick marks for each group. The unusual thing is that they are inclined to an angle, that's all.
Thanks for your interest

Thanks for posting.I think this should go under Glaze Technical rather than "In the studio" sub topic. I will ask the moderators.
Again, great educational resource!!
