Also will help if you purge your ovens and pegs etc..Hi Icon,
we oxidise at 980'c for 5 mins in air and then re-sandblast. We don't usually get tension cracks, however, sometimes there are cracks that are being caused by the bubbles in the porcelain.
I got my colleague to build up another Argipal bridge today, and again she had no problems. I spoke to the UK argen supplier who told me that Argipal is ok to use with Noritake but I wouldn't like to swear that they are right. There seems to be no info in the Noritake instructions as to the cte range of the ceramic which unusual.
Today I'm casting with a new crucible and Argilte 80SF+
