A hard to find blue tint Pyrex glass Flame Ware 1 quart replacement insert (top pan) for your double boiler bottom plus the glass lid. It's the 6762 model, produced from 1937 to 1946, after which the company discontinued the one quart size. Capacity is measured by the upper pot, which holds one quart to the bottom of the stainless steel band.

It has a glass handle and detachable snap-off stainless steel band. The pot measures 5 inches high by 5-1/4" diameter across the rim. Length from handle to opposite rim is just under 10-1/2 inches. The original green stamped Flameware logo on the bottom has disappeared due to use and cleaning. Otherwise both the pot and lid are in excellent, very clean condition with no residue, cloudiness, chips, or noticeable scratches. The stainless steel band is also clean with no rust or corrosion.
