Crystallization of Rutile at cone 6 completely subdued? How?

Thursday 10th June 2010

These glazes are both 80% insight-live.com/material/32">Alberta Slip, but the one on the right employs 20% Ferro Frit 3249 accelerate the melting (whereas the left one has 20% Frit 3134). Even though Frit 3249 is higher in boron and should melt better, its high MgO stiffens the glaze melt denying the mobility needed for the crystal growth.
