Fire extinguishing lid for anthracite carbide M-100. Features: If you do not have a lid, you will need to apply water to stop burning at the end of the carbide, but if you use the lid you can use it to carbonize without watering.

Benefits include no need to worry about drying charcoal after digesting, and work in places without water (need to prepare a fire extinguisher, etc.) It can also be left on the lid when not in use to prevent the contents from scattering in the wind (though it is a simple lid).
