Abstract
A refractory material for forming a refractory product includes a refractory component and a taggant having an amorphous or a crystalline solid dispersed within the refractory material. The taggant is configured to be distinguishable from the refractory component after heating of the refractory product between 300 degrees F. and 3500 degrees F. A method of reclaiming refractory material of a refractory lining constructed from different types of refractory products, the refractory lining having been subjected to temperatures in excess of 300 degrees F., includes demolishing the refractory lining to produce a mixture of refractory pieces of different types of refractory products. The mixture of refractory pieces is analyzed to detect the presence of one or more taggants, and the refractory pieces are sorted into groups based on the detected one or more taggants.
