Showing the effect of a high percentage of light magnesium carbonate in the grid. One can use 40 or 50 % of light magnesium carbonate in the C-corner, with the balance of the fluxes being frit for mid-fire or nepheline syenite for high-fire. Add other fluxes and additives like colouring oxides and rutile if you wish.
