#1716 CD 123 EC&M CO. S.F. Vivid cobalt blue. "A" mold.
This flared skirt mould variant with rounded dome has been designated as mold type “A.” Flared skirt variants were placed in service during the early years of EC&M production. The Electrical Construction & Maintenance Company was formed in late 1870, and production of the embossed “A” mold EC&M’s likely commenced shortly thereafter.
Perhaps one or more glass houses producing blue soda bottles in the 1870's in the San Francisco Bay area might have used the same glass batches to manufacture insulators.
Cobalt blue examples were used in several different locations, most surfacing in California and Nevada.
These rich blue beauties can be found in varying intensities and depth of color, this one possessing excellent depth of color and richness. The color is so saturated, that a purple tone is present when viewed in some light sources.
An extra tall example, with 4-5/8" height.
Pinkie nail flake on dome edge. Shallow base chipping. Sizable surface chip on left front skirt. Diagonal fracture traverses 2/3 the distance up from the base on left reverse skirt.
