Cleaning Firebricks-Best Way?
Posted 20 August 2014 - 06:36 PM
I was thinking I could just load them in an electric kiln, preheat to dry them and fire them to around 700 degrees to burn off the organic material.
Is there a better way?

Since you let them get wet-most likely they still are wet. You better go real slow heating them up to 212 degrees where steam forms.This needs to be a slow fire.
Soft brick do not do well getting wet-hopefully they did not freeze?
After firing you may still have to brush them.

Don't pack too tight.... they will have significant thermal lag....... since they are designed to be insulators. Stak in an open pattern to get the faces hot..... and burn off the junk. I'd go toe 1000-1100 F.

i can take them off your hands if you dont want to clean them........
i'd candle them 180 ish overnight, id even go to 210F for a few hours
think loosely packed kiln, with minimal brick overlap

why not just pour bleach on them and use a brush? wear white.
