• Briquettes are usually made out of dry sawdust, which is compressed into different shapes and sizes. However, they can also be made out of peat, straw, leaves, rapeseed and even bio-digestant. They tend to be supplied in small 10kg bags, or blocks.
• A briquette is heavier than a similarly sized log due to its higher density, and a lower moisture content (below 10%), so it burns more efficiently for those with less storage.
• A briquette can be used in a similar way to logs (open fires, stoves, boilers) and will tend to burn for longer and at a higher temperature. Caution is needed when placing on open fires as they tend to expand when hot.
Some forms may produce higher ash content; this will depend on the raw material used.
• Also be aware that if they get wet, they will disintegrate so dry storage is vital.
