Fire Brick Quality - Chemicals
 
Hi everybody..

At the place, where we're about to buy the firebricks, there are a few times used ovens. Most of the firebricks are giving out a kind of white chemical, it looks like salt structure but i'm afraid it's a kind of mold or fungus.

The salesman said that it's normal, after the heat and cooling down, the firebricks are sweating humidity but after you fire the oven, they disappear..

Has anyone experienced something like that? Could it be something dangerous for food or something natural about the firebricks and/or about the quality?

I'm in Israel, we have to be on schedule, so we have to buy the bricks in the next couple of days. I'll be very happy if someone can answer as soon as possible..
