A single walled container for storing hot or cold foods or liquids having a layer of insulation comprised of void containing particles held together with a binder applied to the outer part of the sidewall. The insulation layer provides a controlled amount of insulation which is sufficient to prevent pain to the fingers yet it transmits sufficient heat to warn the user of the temperature of the container's contents. The binder may be any thermoplastic or thermoset resin, and other ingredients may be added to the binder to control viscosity, density, or color.
