Between 1945 and 1949, Corning Glass Works collaborated with the U.S. government to make Pyrex dishes which they painted primary colors. These were yellow, red, blue, and green. The primary colors bowls which went for $2.50, became the first Pyrex opal ware ever to be produced.

In the collaboration, the U.S. government wanted to make substantial, light, and unbreakable dishes for its soldiers during WW2. During this period, the color bowl or dish set had no standard model numbers.

From 1955 until 1956, Corning Glass Works brought in additions to the opal ware Pyrex pieces. They named this the Desert Dawn pattern, which came in yellow and pink. This brown-dotted kitchen glassware was among the first opal ware Pyrex pieces that the consumer market loved.

Glass Markings

Inspect your pyrex piece while paying attention to any chips, glass markings, stamps, or logos. Ancient pyrex has markings at the bottom of glass pieces. Also, it should have the word ‘PYREX’ in a circle with the company’s logo, C.G., standing for Corning Glassworks.

However, the circle format ended, and straight lines replaced it in the 1960s. Also, pyrex manufactured around the mid-1950s had a ‘MADE IN THE U.S.A.’ and a trademark symbol or wording. The earlier productions also had a tiny figure blowing glass included in their stamps.

Inventory Number

Some casserole bowls and dishes have inventory numbers stamped at the bottom. You can use the sequence and model numbers to tell their years of manufacture.

How Can You Tell Old Pyrex from New Pyrex?

The best way to tell old pyrex from new pyrex is by checking the markings or chips on each piece. You will find the oldest pyrex markings like ‘PYREX’ and ‘CG’ in capital letters in a circle at the bottom of each mixing-bowl. The circle got discontinued in the 1960s, with straight lines replacing it.

Therefore, if you find pyrex with markings over straight lines at the bottom, there is a higher chance that the company produced it after the 1960s.

Another way to tell old pyrex from new ones is by checking the colors and patterns. If you come across clear glass pyrex pieces, it shows that they produced them between 1915 and the mid-1940s. Plain pastel and primary-colored pyrex pieces followed suit until the 1950s, whereas patterns continued until the late 1980s.

Is Vintage Pyrex Safe to Use?

Old pyrex pieces, which came in clear glass form, contain no lead, making them safe to use. On the other hand, there are vintage pyrex pieces painted in colors with high lead levels.

While it is only the outer part of the collector’s item that contains lead, you should be careful when collecting cracked vintage pyrex pieces. When you cook using these pieces, the lead may seep through and end up in food meant for consumption, posing a severe health risk.

They are safe if you are collecting vintage pyrex pieces purely for sentimental value and aesthetic and decorative purposes. Also, note that they are not dishwasher safe. All in all, prioritize your health and those around you by checking for paintings and crack lines before use.

How to Find Vintage Pyrex?

You can check on Etsy, eBay, and Facebook Marketplace for vintage pyrex pieces. In addition, check local antique shops, flea markets, antique thrift shops, and antique garage sales occasionally.

Alternatively, you can talk to vintage pyrex collectors to guide you on how you can find them. If they are willing to sell some pieces to you, let them.

Conclusion

When collecting vintage pyrex, check for markings such as paintworks, chips, color, and logo at the bottom of the dish to determine how old they are. Still, some vintage pieces may not have such markings. In such cases, seek professional help from vintage pyrex experts to avoid buying fakes.
