    I have some extra ceramic fiber blanket I bought from Forno Bravo and I would like to use it to insulate a door. I have a concern of it being touched by the welder. Will it burn or catch fire by an open flame?
    It may melt in small places where the arc touches the metal, may but I doubt it.
    From memory ceramic blanket is rated at 1500c, welding arcs are 3000c that is at the weld puddle, mm's away it will cool rapidly.

    My Build.

        1260C is the working limit, but melts at 1700C Alan. Shouldnt have many dramas.

          I knew that as soon as I posted it, my gas forge got to 1550c I think the other day and the blanket glowed like buggery but was still there....

            I have one small question:

            If you use the ceramic fibre blanket in a WFO wouldn't some particles be in touch with food should the WFO develop some cracks with time? (which they eventually do)

              The new generation ceramic fibre is exonerated as a class 2 carcinogen unlike the older stuff. That means some lab rats got tumours but none reported in humans. The new fibre is biosoluble so doesn’t cause problems if inhaled. There has never been a concern about ingestion only inhalation. Check your MSDS in the toxicity section on the blanket you have or are buying to see if it is biosoluble.
