Flat blocks, hex tiles, or natural lump?
Flat blocks (F40 and F50) fill a chimney starter evenly and are the retail pick for 3 kg and 5 kg bags. Wide 60 mm hexagons (B10 and B15) tile into a gap-free bed without hot spots and keep a restaurant grill going for up to 3.5 hours on one lighting. Natural shell lump lights fastest and peaks hottest at a lower price per ton, though the pieces range from 20 to 80 mm. Supermarket programmes take blocks; restaurants with open grills often run hex and lump side by side.
