We were pleasantly surprised to find that after 16 years of operation, when we rebuilt the tapholes of our HF3, there was still a large part of the Ceramic Cup made of Coranit® AL (approx. 20 cm), at least up to the tapholes. The Saint-Gobain Ceramic Cup, coupled with good lining management, protected the carbon perfectly. The carbon was virtually intact throughout the hearth.
