    Re: High Heat Mortar Primer

    Question about the home brew. According to the book "Bread Builders" by Allan Scott, MASONRY CEMENT is Portland Cement with lime added. So instead of taking portland cement and adding lime, could I use Masonry Cement? If so which type and would it then be 1 part masonry cement, 1 part fireclay and 3 parts sand?

    Thx

    I can't help myself, so here is Nick's buried testimonial for Refrax from an earlier posting. From the source...

    "I've used the 1,3,1,1.. The heatstop 50, and have found (Forno Bravo's) Refrax to dry way harder than both. If I slow cure it with damp burlap it'll take a bunker buster to break it I reckon. "
    -Rebrick (himself)

    You can take that to the bank. Thanks Redbrick.

    An update. I have created a High Heat Mortar page within the Pompeii Oven plans, with links to it from the Materials, Oven Dome, Overview, etc. pages. This should point all of the new builders to the same place for the same alternatives and recipes.

    Let me know if you find reference to any older information on other Pompeii pages, and I can fix it.

    The original recipes works great

    Don't worry. The original recipes works exactly the same. The main different is texture in application. The two mixes are very close. Also, 1:3:1:1 is so easy to remember.

    I have a question. I have been putting my firebrick up with which i guess is your original fireclay mix of 8 parts sand, 3 parts portland and 2 parts fireclay. But now i am reading about the new mix of 3 sand, 1 portland, 1 fireclay and 1 lime. Am i going to be ok with the other mixture? I am up to my 7th chain. I will change over from this point. please inform.
