Abstract: An infrared ray reflective coating for application to insulative materials comprising aluminum particles in an aqueous acidic binder slurry, a hardener, and a coating cement having about 96% of a mixture of Al.sub.2 O.sub.3 and SiO.sub.2.

Abstract: A portable radiant heating apparatus includes a pair of linearly extending members pivotally attached to one another adjacent a first end thereof and pivotal about the pivotal attachment to be generally parallel to one another. A lamp receiving electrical socket supported on the other end of each of the members receives a high intensity infrared lamp electrically arranged to receive power from its socket via means for connecting each of the sockets to an electrical power source. A concave infrared reflective shield is provided about each of the lamps and shaped to direct the light from each of the lamps generally uni-directionally. Thermal insulation means are also provided to protect the members and shields from the heat generated by the lamps.
