Charcoal has been used for centuries in many different cultures around the world, including ancient Greece where it was discovered by man. It wasn’t until about 300 years ago that experiments were done on its chemical properties and how they are related to combustion leading to today's modern usage of natural lump briquettes (charcoal made from wood and other hard ingredients). We now know that what makes these unique compared with common charcoals is their production process which creates more porous surfaces within them allowing for faster lighting times, better airflow control during burning, less ash build-up over time, etc. Making quality natural lump briquettes (charcoal made from wood and other hard ingredients) requires special techniques that are still employed today by some of the top brands on the market. This includes using heat-resistant materials like ceramic, brick or steel to hold charcoal inside instead of common metal drums which can leach chemicals into coals over time as they burn down.
