JSG ESTATE LIQUIDATION

This remarkable lot represents a mid-20th century home chemistry and laboratory collection assembled in a repurposed cardboard box labeled 'Chemistry' and 'Illustrated Home Library Encyclopedia.' The centerpiece items include an Ames Diagnostic Kit No. 2000 designed for detection of urine-sugar (Clinitest), acetone (Acetest), albumin (Bumintest), and occult blood (Hematest), representing an important era in home medical diagnostics from the 1950s-1960s. Two boxes of Denver Fire Clay Company (DFC) Filter Paper No. 2964, White Smooth Surface Close Texture Medium Filtering Speed, are particularly notable as Colorado-provenance scientific supplies — the Denver Fire Clay Company was a well-regarded Denver, Colorado supplier of laboratory and industrial materials with offices also in Salt Lake City, El Paso, and New York. The lot also includes a vintage Microscope Manual of Instructions booklet, numerous glass laboratory items including test tubes, Florence flasks, glass globes, beakers, Erlenmeyer-style flasks, glass droppers/pipettes, a tube cleaning brush, amber glass reagent bottles with Denver Fire Clay Company labels, cork-stoppered vials, a red painted wooden test tube rack, dissection needles/probes, and various wrapped paper packages of additional supplies. The glass labware appears to be mid-century American scientific glass, consistent with 1940s-1960s production. Condition is overall Good to Very Good for the glassware with no obvious breaks visible, though some pieces may have minor chips not visible in photos; the cardboard boxes and paper ephemera show age toning, foxing, and wear consistent with 60-70 years of storage; the Ames Diagnostic Kit box shows a handwritten name and light soiling; the filter paper boxes show significant age toning and staining to the exterior cardboard. Contents have not been fully inventoried and are sold as-is. This lot is an exceptional find for science history collectors, medical antique enthusiasts, Colorado history collectors, and prop stylists.
