Step-by-step to do a formula-to-batch in Insight-Live.com
Insight-live does not automate formula-to-batch calculations, but it does assist in doing them. And it provides the tools to create an audit trail of test results, pictures and notes and a path to document subsequent adjustments. Along the way, you gain material knowledge and intuition. In this example, we derive the recipe of materials needed to source the oxide formula of a zinc clear cone 6 glaze (sourcing the oxides needed using a Ferro frit and other common raw materials). We'll create the target in a panel, start the batch in a panel beside it, supply the B2O3 from a frit and then the fluxes from feldspar, zinc and whiting. Then finish by rounding out the Al2O3 and SiO2 from kaolin and silica. The picture below shows the panels, the original target formula on the left and the final derived recipe on the right. The derived transparent glaze is on the inside of the mug and the outside is G3875, another zinc clear with iron and chrome added to produce the orange.

You will see examples of replacing unavailable materials (especially frits), fixing various issues (e.g. running, crazing, settling), making them melt more, adjusting matteness, etc. Insight-Live has an extensive help system (the round blue icon on the left) that also deals with fixing real-world problems and understanding glazes and clay bodies.
How to choose ceramic materials to source needed oxides
How does one choose which material to source each oxide needed when doing glaze chemistry formula-to-batch? It is easy to overthink this. Insight-live has thousands of materials of which you likely only have a few. By tapping any of the oxide names in the calculation in a recipe panel it becomes evident quickly that it is fairly simple to know which material to source each oxide from. When ZnO is needed it is sourced by zinc oxide, SiO2 by silica, TiO2 by titanium dioxide, Li2O by lithium carbonate or spodumene, MgO by talc or dolomite, CaO by whiting or wollastonite, Al2O3 by kaolin or ball clay, KNaO by feldspar. The tricky one is B2O3, you’ll get that from frits available to you. The frit you use will bring many of the other oxides so their main sources (the other materials just listed) will need adjustment. This being said, the above must be tempered by material cost and by how the solid state and physical properties of materials affect slurry rheology, glaze laydown and drying.
