Vivant’s patent pending Firecore™ heating element is the first of its kind, a revolutionary heat source that uses a spiral electrical trace placed inside an SIO2 crystal cup, this allows for an all silica glass surface to evenly vaporize your material cleanly and without it touching any metal or contaminants, this technique produces smooth vapour with the very best and purest flavours. Two opposite air intakes are built in to provide a balanced, powerful airflow and the food grade stainless steel cools the vapour and prevents spit-back.
