Pyrex Pie Plate Value Guide

Vintage Pyrex pie plates are highly collectible due to their transition from industrial railroad glass technology to a revolutionary household staple. These pieces are prized for their superior thermal shock resistance and the iconic durability of the original American-made borosilicate formula.

What Is Pyrex Pie Plate Worth?

The typical price range for Pyrex Pie Plate is $10 - $20 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the glass, specifically the absence of 'dishwasher haze' or deep utensil scratches.
• Presence of unique features like scalloped edges or integrated handles found on specific era models.
• The specific production decade, with 1940s-1950s thick-walled versions often fetching higher prices.
• Clarity of the embossed branding and manufacturing marks on the underside.

How to Identify Pyrex Pie Plate?

• Look for the circular 'Pyrex' trademark stamped into the bottom of the clear glass.
• Check for the 'Made in U.S.A.' mark which distinguishes these from modern international reproductions.
• Examine the glass for a slight blue or green tint characteristic of mid-century borosilicate compositions.
• Identify the specific model number usually embossed near the rim or on the base of the plate.

History of Pyrex Pie Plate

Pyrex, a brand of Corning Inc., introduced its first line of bakeware in 1915. Developed from a borosilicate glass formula initially used for railroad lantern lenses and battery jars, Pyrex quickly became a household name due to its durability and resistance to thermal shock. Its introduction revolutionized home baking, offering a non-reactive and easy-to-clean alternative to metal bakeware.
