  • chimney vent and insulated hearth issues

    I’m a first timer, an inexperienced builder and mason. Can someone help me with my issues…hopefully their not problems.

    1. My vermiculite/cement poor swelled upward about ¼” overnight. What happened? Do I just scrape or sand the oven floor to make it level?

    2. The surface skin also blistered in places making the surface skin crumbly. What happened? Do I lay my oven floor bricks directly on the now level crumbly surface? Is setting the bricks into a fireclay skim important?

    3. Is the chimney vent immediately above the inside or outside perimeter of the oven dome?

    That’s enough to get me to the next question.
