Vintage Pyrex Gold-Tinted Glass Baking Dish

This item is a circular, vintage baking dish or bowl manufactured by Pyrex. It is constructed from thick, pressed borosilicate glass, featuring a distinctive translucent gold or amber-colored tint often associated with mid-century glassware lines. The physical form is characterized by a wide, flat circular base and rounded sides. A primary identifying feature is the embossed mark on the base which reads 'PYREX' in capital block letters, along with numerical codes such as 'M-3' visible at the top and additional size formatting at the bottom. These markings are cast into the glass during the molding process. The glass displays moderate surface wear consistent with age and domestic use, including fine scratches on the interior and exterior surfaces. Notably, there are some small bubbles or 'seeds' visible within the glass matrix, characteristic of older manufacturing batches. Most uniquely, the dish is shown through a distorted perspective due to the refractive index of the thick glass, reflecting the surrounding environment. Based on the embossed typeface and the golden hue, this likely dates from the 1960s to early 1970s, a period when colored ovenware was highly popular. The craftsmanship is robust, intended for high heat resistance, reflecting the industrial quality standards of the Corning Glass Works during this era.
