It’s been 25 years since Corning launched Pyrex in 1915! And although the company even stopped its production in the 1990s, there’re still no brochures to value the old Pyrex items rightly. And sellers add price tags as they like without any verification!

How Can You Tell Vintage Pyrex From New Pyrex?

Rare & Valuable Vintage Corningware Patterns

You can tell if your Pyrex is vintage by its aged features – Amber patina, Uneven thickness, and Clear or Pastel finishes. But there are more fine details that will help you verify:

  • Low-expansion Borosilicate or Soda-lime walls
  • Branded ‘Corning’ or ‘Pyrex’ marks with model numbers
  • Bold & intricate designs from the 1900s glass artists
  • Superior shock, electrical & chemical-resistant glass

When & How Did Vintage Pyrex Products Evolve?

Once a simple glass line, now a beloved ovenware brand, Pyrex products went through different design and evolution phases as follows:

The Naming Phase: 

The 1900s people indeed used some of the thickest skillets and dishes. But those weren’t oven-safe and cracked with heat. That’s when Corning introduced Pyrex (named after the Greek word ‘Fire King’). And since it had borosilicate glass, it didn’t crack in ovens!

The Launching Phase: 

Corning launched Pyrex as a simple, 12-piece dish set (Egg, Bread & Dinner plates.) But, with time & sales, they explored some patterned bowls & casseroles too. In fact, some early Berry or Spring Blossom designs fetch good returns even today!

The Designers Phase: 

By the 1930s, people got bored with the same Berry & Floral designs. So, Corning introduced butterflies, daisies & striped designs. Some even had red or orange designs, making them more popular.

The Declining Phase: 

The 1940s was the era of the Economic Depression. So, makers switched the ‘borosilicate glass’ with cheaper ‘soda-lime’ glass. But sadly, ‘Pyrex’ lost its quality, making it cheaper than before.
