Nothing compares the fired properties of frits as well as a melt-flow comparison. But frits need a binder to make them plastic-formable. I shake together in a bag 3.25g VeeGum with 100g frit, then add 35g water and overnight them, that produces a nice consistency. This much VeeGum is not enough to affect the melting behavior, but it makes them pretty workable (however each frit does exhibit different tactile characteristics). I roll them into 12g (wet) balls, then dry them. They fit nicely into the reservoir in the tester.
Frits are used in ceramic glazes for a wide range of reasons. They are man-made materials of controlled chemistry with many advantages or raw materials.
