Re: Type S Mortar + Fireclay = good mix?
Fx,
I used plaster sand for my homebrew and it was very easy to work with. One cautionary note, I paid attention to people's mortar mix and the people who changed the formula seemed to have problems with cracking. I used the formula listed in the FB plans, cured slowly and had nothing more than some hairline cracks on the exterior of my dome, if I had put the mortar over the entire dome instead of just the soldier course I wouldn't even have known they were there. No need to reinvent the wheel unless you have some information from somebody you trust that gives you a reason to tweak the formula.
