Oh wow, congratulations! You look pleased...

Looks lovely, beautifully shaped dome there.
About your questions: I was advised to build the arch/vent bit before curing, because otherwise you'd have to cure a second time when the vent is in place...
Question two: the higher up, the hotter it gets... so I'd guess that the sides of the entry arch would be ok with regular mortar, while top of the arch and the vent would benefit from the heat resistant stuff. Any other opinions on this?
