Question: What Pyrex patterns are most valuable?

What is the difference between Pyrex and Corningware?

Essentially, the main difference between Corningware and Pyrex is that Corningware tends to be smaller, and more aesthetically pleasing. Some prefer to use Corningware to bake, and Pyrex for storage. For others the opposite is true, they prefer Pyrex for baking and Corningware for serving.

Why was CORNINGWARE discontinued?

More than 750 million pieces of CorningWare have been manufactured. In 1998 however, due to slumping sales and retooling of manufacturing plants, Corning sold off the CorningWare and Pyrex lines to World Kitchen, LLC. Under new direction, the CorningWare and Pyrex lines are still pretty strong, although different.

Does Pyrex break in the oven?

Dont preheat the bakeware in the oven. According to Pyrexs safety and usage instructions, “While the glass is designed for temperatures typically used in baking, it can break when exposed to the direct heat element while the oven is preheating.”
