Lid Maintenance and Repair
During the firing your lid will expand and contract. It’s necessary to tighten the band clamps on the lid after each of the first three firings. These clamps
should be checked periodically after and tightened as needed.
Small, hairline cracks may appear in the lid and bottom. This is normal and does not affect the firing in any way. Should chips or large cracks appear they
should be repaired to prevent sifting or becoming larger. Small chips may be cemented back into place. For large chips, a portion of firebrick may need to
be removed and a new brick, cut to size, cemented in. Sand smooth.
