Hi. A student is about to mix up a glaze from an old book Recipe not
available tonight..) It calls for norflot spar. What is the proper sub? I
suggester Custer or G-200. Any info out there?

My files say Norfloat K has this analysis:
65.8 wt% SiO2; 18.5 Al2O3; 2.5 Na2O; 12.0 K2O; 0.4 CaO; 0.1 Fe2O3;
LOI 0.3.
Because of the high K2O neither Custer nor G200 will sub directly
without adjusting the Al2O3 and SiO2 contributions from other materials.
good tests. Bye. Tom B.
