Vintage Blue Milk Glass Hen on Nest Base

This item is a circular base for a pressed glass lidded dish, specifically matching the well-known 'Hen on Nest' pattern. It is crafted from opaque turquoise or 'robin's egg' blue milk glass. The design features a complex pressed geometry, with a central sunburst or stylized floral medallion on the bottom interior, surrounded by an intricate ruffled or pointed 'sawtooth' rim border. The exterior walls appear to have a basketweave or cross-hatched texture characteristic of mid-century American glass manufacturers. Based on the vibrant turquoise hue and the specific pattern of the pressed glass, it is likely manufactured by the Westmoreland Glass Company or potentially Boyd's Crystal Art Glass, dating to the mid-20th century (circa 1950s-1970s). The condition appears good with no significant cracks or large chips visible from this angle, though the sawtooth edges on these pieces are highly prone to 'flea bite' nicks. The piece displays a matte to semi-satin finish typical of high-quality vintage milk glass. There are no clearly visible maker's marks in the image, common for Westmoreland pieces which often used paper labels.
