Cold-roll Steel Sheets are the primary material used in the construction of this Roast Duck Oven Furnace. The furnace is designed with a dimension of 30x26cm (11.8x10.23in) and a carbon capacity of 4lb (1.8kg).

The inner wall of the furnace is lined with a layer of refractory mud, which is a mixture of fireclay and cement. This refractory mud lining is a crucial component that helps maintain the structural integrity and heat-retaining properties of the furnace.

It is important to note that the refractory mud lining may develop slight cracks or become slightly uneven as it dries. This is a normal phenomenon and not a quality issue. The furnace can still be used safely despite these minor imperfections.

The furnace is designed to be suitable for a range of fuel types, including charcoal, bamboo charcoal, and special wood. The diameter of the inner hole at the base of the furnace measures 11-11.4 inches (28-29cm), ensuring compatibility with various furnace setups.

The package size of the Roast Duck Oven Furnace is 14.96x12.20x12.60 inches (31x32x38cm), and the shipping weight is 13.11lb (5.96kg).

In summary, this Roast Duck Oven Furnace is a well-designed and durable product, featuring a cold-roll steel construction, a refractory mud lining, and compatibility with various fuel types. The minor imperfections in the lining are normal and do not compromise the safety or functionality of the furnace.
