Abstract
A wax-based brick such as a wax and sawdust brick for starting fires in fireplaces and the like is shaped to reduce the area of contact between adjacent bricks in a stack to make the bricks easy to separate from the stack even when the wax has slightly melted. The bricks may have a central cross-section which is octagonal, hexagonal, trapezoidal, or generally rectangular with convex or concave upper and lower walls. The end portions of the bricks have generally rectangular cross-sections to facilitate stacking.
