In fact, one set of vintage Pyrex fetched around $US$1,800 on Etsy.
And this JAJ Pyrex Hawthorne Spacesaver is currently selling for AU$759.32 on Etsy, while a set of American mixing bowls is going for AU$865.05.
So what makes a vintage Pyrex piece valuable?
“It's all in the eye of the beholder at the end of the day. What might be valuable to some may not be valuable to another,” vintage Pyrex expert and author Stan Savellis told Better Homes and Gardens.
“Many US pieces that go for higher values tend to be test pieces or patterns that never made it officially to market.
“Other pieces that valuable and sought after, like turquoise patterns such as Butterprint or Starburst (both from the US), have a high value yet come up often for purchase.
“Other favourites tend to be Snowflake, which was made in both the US and the UK. The UK versions, which also come in pink and a deep coral (red) colour, tend to be highly sought after.”
How much is vintage Australian Pyrex worth?
“Some Australian pieces are sought after more so than others, such as Flannel Flowers or the Scalloped Pudding Bowls.
“Whilst they may not go for that much, a Flannel Flowers oblong casserole might get to $300 and a pudding bowl might sell for a good $50 each (they're actually very small too, so that's a lot!)”
The rarest piece of Australian Pyrex is the Carnival design, which was produced in the early 1960s.
“It's coloured enamel sprayed on clear glass with a really cute carnival scene in white,” explains Stan.
“So far we've seen it in olive green, bright orange and a buttercup yellow. The last time I saw one of these sell it was greater than AU$500.”
