  • If the wood splits, splinters, or catches fire, it can result in extensive damage and safety risks.

Beware of Hot Spots and Fire Risk When Microwaving Wood

Wood’s poor heat conduction properties make it susceptible to creating hot spots when microwaved. Hot spots occur when certain areas of the wood heat up more rapidly than others, leading to uneven cooking or heating. These hot spots can not only affect the quality of the food being cooked but can also pose a potential fire risk.

As the hot spots develop, the area of the wood in contact with the microwaves may exceed a safe temperature threshold. If the wood reaches its ignition point, it can catch fire, resulting in a potentially dangerous situation. Therefore, it is strongly advised to avoid microwaving wood to prevent the development of hot spots and minimize the risk of fire.
