The herringbone fireboxes built by Superior Clay Corp. feature firebrick splits with 9" by 1-1/4" faces laid in a vertical herringbone pattern. The boxes are shipped in four sections (inner hearth, two covings and the fireback) and are easily erected at the job site. The pre-made fireboxes save master masons much time and aggravation and allow less experienced masons to build beautiful herringbone fireboxes that would ordinarily be beyond their ability.

1. Lay the inner hearth level and centered in a bed of mortar. Use standard firebrick or optional herringbone hearth from Superior Clay.
	2. The next day, set the covings and the fireback in place in the refractory mortar provided on the inner hearth and support the pannels temporarily with concrete block or lumber. 3. Build a solid masonry backing wall at least 4" thick to permanently support the firebox.
4. Fill any cracks between the four pannels with refractory mortar and wash with clean water. 5. The firebox is ready to be treated, like any other - carefully - until the solid masonry has cured.
