Refractories are the plates, posts, and blocks that let our tile and brick go through our kilns.  Although they can withstand high temperatures, they are easy to break.  Each year, we replaces broken refractories.  In the past, broken refractories have been crushed into aggregate along with fired scrap but recently we began a program to return them to our local refractory supplier to use as grog.  Grog is ground up refractories that help new refractory pieces use less energy and material to fire and produce.  This helps our supplier because they need more grog.

Ironrock is pleased that our broken refractories will be re-used to make new refractories and add to the list of materials we recycle and re-use.
