The invention relates to a barbecue marmite. The barbecue marmite comprises the following components in parts by weight: 30-80 parts of green crucible, 5-30 parts of sandstone, 8-25 parts of spodumene, and 3-20 parts of slag. The invention also provides a sintering method for the barbecue marmite, which comprises the following steps: material preparing, grinding, mud preparing, mud kneading, moulding, drying, and sintering. The barbecue marmite employs spodumene, and uses the characteristics of stability and heat resistance of spodumene, under condition that the marmite keeps original advantages, the barbecue marmite can bear dry burning at high temperature of hundreds of degrees, practicality of the marmite is greatly increased, the spodumene contains a plurality of mineral matters, and can be decomposed to alkalescent mineral matters through heating, trace elements required by human body can be supplemented, and the spodumene has certain health preserving efficacy; in addition, the marmite has the characteristics of uniform heat transferring and fast heat transferring, slow heat radiation, and strong insulation capability, the food can be rapidly heated, and the requirements of crispy outside and tender inside can be achieved.
