Blend Frits F3124 and F3110

Yes, mixing them can be very useful to get a certain chemistry. Especially for lower temperature glazes where you’ll want the boron from 3124 (or 3134) and with high sodium content from 3110.

I typically use 3134 instead of 3124 because it’s lower in Alumina but has a similar amount of Boron, then add EPK for some Alumina and to help suspend the glaze. Use a lot of 3110 for Sodium content, and of course zinc and silica.

I don’t necessarily think about mixing/blending them, I’m looking for certain chemistry using UMF. For a cone 6 glaze that means about .5 Zinc, about 1.8 Silica, .2 or lower Alumina, about .15 Boron and then about .2 Calcium and .3 Sodium. That’s for a cone 6 glaze, and for cone 10 would simply remove the Boron keeping everything else the same.

The UMF calculator on glazy.org is great for this.

Howdy folks, recently running low on 3110 tried to convert 413 by adding what seemed to be the right amount of gerstley borate. Right after that result bought more 3110. Cheers, Gordon Good luck with the hammer mill Jim.

I've done years of tile work as well.It all adds up. It only bothers me at night so far but im using a respirator instead of a dusk mask when im stirring up dust and trying to keep the studio cleaned up ( that also makes the wife happy.
sort of closing the barn door after the horse is gone but im trying keep it from getting worse

Thanks Gordon, Where are you?im in northern California. If you ever find yourself in the area look me up. PM sent
