Is lump charcoal more natural than briquet charcoal?

The exact ingredients vary by brand. However, both briquets and lump charcoal contain all-natural ingredients. Lump charcoal is composed entirely of charred wood. Briquets are primarily char, but they do contain some other ingredients. These additional ingredients combined with the briquet’s shape and how it is produced provide the consistent grilling experience. Some ingredients — coal, limestone and borax — are naturally occurring minerals. Wood char and cornstarch are both natural products.
