solid alcohol.

solid alcohol is also called "alcohol block" or solid fuel block. Solid alcohol is not solid alcohol, and the pure substance is liquid at room temperature. Instead, it is made into solid form by adding coagulant into industrial alcohol. Solid alcohol, or solidified alcohol, is convenient to use, transport and carry, causes less environmental pollution when burning, and is safer than liquid alcohol. As a solid fuel, it is widely used in catering, tourism and field work.
