I work for Specialty so my opinion is going to be biased but I can say they specialize in refractory and everyone works hard cause it is tough work from laying brick, shooting shotcrete, casting ladles, ramming, doing demo, etc.....

They have the know how and the supplies that you need for foundry and blacksmithing work. They sell to backyard hobbyist and large companies alike. No complaints here
