Interior shot of Glassray of Tacoma. Pictured left to right are Pat Pannell, office assistant, Tom Livermore, owner and Jack Foley, co-owner. Glassray sold apparatus for radiant electric heating. Radiant heat was transmitted by radiation, as opposed to that transmitted by conduction or convection, and was popular in the fifties. It supplied affordable, efficient and clean heat. Another popular item, the bold checkerboard tile floor dominates the look of the office. Radiant heat panels are on display in the office. Pat sits before a typewriter as the two owners pose standing for the picture. Long industrial type florescents supply the lighting.
