maybe slow your heat rate down too . Let the zr absorb more heat
Great pointyou need to increase slow heat and slow cool more, the bigger the frame work gets .you have also dried out the job far too quickly Zi is a poor conductor of heat so it will take time.What you have done is an excellent example of why porcelain was chipping off Zi frame works in the early days dont feel bad the vm9 instructions dont cover this very well i would recommend looking up the ZZ site for firing tables and then adjusting for vm9.When i did a study with a group of pros specialists we even contacted vita to check their tables because when we fired large amounts at once we got exactly what you were getting. Vitas response was oh yeh you should cool it slower only solved half the problem .Grind it all off and start again.
