Built from heavy-gauge stainless steel and packed with a dense ceramic core, it reduces fuel consumption while acting as an integrated heat deflector so you get steadier temperatures and less fire tending during low-and-slow cooks. The raised feet and open-bottom design improve airflow and make ash removal quick and tidy.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the onlyfire set save charcoal and extend burn time?\u003c\/h3\u003e\n\n\u003cp\u003eFuel savings come from the dual-material design: a stainless steel frame surrounds six high-density ceramic plates that form an insulating thermal barrier. By slowing how quickly charcoal delivers heat, the ceramic core reduces consumption and prolongs usable burn life.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThermal storage from ceramic plates reduces peak heat loss and evens release.\u003c\/li\u003e\n  \u003cli\u003eMeasured fuel reduction of roughly 30–50% compared with bare-steel baskets.\u003c\/li\u003e\n  \u003cli\u003eDesigned for multi-hour burns—holds enough charcoal for 8+ hours of smoking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this maintain steady temperatures for smoking and searing?\u003c\/h3\u003e\n\n\u003cp\u003eYes. The ceramic core doubles as a heat deflector that softens thermal spikes and shields the dome from direct radiant shock. That stability helps you hold target temps for long smokes and achieve consistent sear or roast performance when needed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBuffers sudden temperature swings for consistent low-and-slow cooks.\u003c\/li\u003e\n  \u003cli\u003eHelps maintain 225°F for brisket-style smoking with fewer adjustments.\u003c\/li\u003e\n  \u003cli\u003eUseful for reverse searing and longer roasts where steady heat matters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the fit and cleanup work in compatible grills?\u003c\/h3\u003e\n\n\u003cp\u003eonlyfire engineered the basket to be a precise drop-in replacement at 18.2\" wide by 10\" high with built-in feet that ensure a wobble-free install.
