Hi Sam

What's your charging schedule like for the Glasma? I'm running a slightly different formula (702A) than the one that you get, but I'd be interested to compare. The instructions that I received from the UK supplier are:

Raise furnace from working temp (2017F) to 2282F
Top up crucible with batch, allow 30-40 minutes between charges
Maintain furnace at 2282F for five hours after last charge
Ramp down to working temperature, but allow 1.5-2 hours before working

I include a squeeze down to 1900F and work at a slightly hotter temperature (2050F), but otherwise it works pretty well. If you're loading at a colder temperature, are you raising it up for the fining part of the cycle? Or holder it longer at the lower temperature?
