Notes

This analysis was confirmed with Fusion Sept 2013. Excellent for replacing Spodumene in glazes (to eliminate its frothing and bubbling issues), this contains a higher percentage of lithia plus contributes other oxides that most glazes need.

This is an example of how much sense it makes to use a fritted form of a flux like lithia rather than the pure, and very troublesome, oxide material. And it is fairly easy to do calculations (e.g. in your insight-live.com account) to substitute zinc in many existing boron fluxed recipes.

This should be more commonly available than it is. Volume users buy this by the pallet for their production, it's high cost amortizes down well considering the benefit it brings. A typical potter would be aghast at the price. Until he saw what this can do!
