G2926B Reduced COE (Li2O)
Total:100.00 Auto Unity Formula
Notes *Remember, the first thing to try to reduce the thermal expansion of G2926B is using 325 mesh silica (or ball milling the slurry). That alone will assure that all silica in the recipe actually goes into the melt, that means that the physical thermal expansion will be as low as the calculated one suggests it should be. If that is not enough, then try this recipe. Use 325 silica in this one also to get the lowest possible expansion. Pictures G2926B vs J shock test There was no crazing at 320F, but at 340F 2926B has five cracks and this has one at the edge. 2926J on P380 The surface is brilliant and clear. G2926B vs J Cone 6 Fluidity G2926J is flowing a little more. Fired character is very similar to B.

G2926B Reduced COE (MgO)
Total:100.00 Auto Unity Formula
Notes *This is an adjustment to G2926B to reduce its thermal expansion. However, before trying this, we recommend ball milling the G2926B or using 325 mesh silica in that recipe. Only if those do not work, then try this (use 325 silica in this one also, the fine particles assure all of it melts). Pictures G2926S after 300F:IceWater test on P300 No crazing after the test. P300 after 300F:IceWater test S is not crazing after two days. B crazing in the cold water.
