Vintage Pyrex Homestead (1976-1980) Design Milk Glass Casserole Dish.
When tested with an XRF instrument this casserole dish had the following readings:
With scope focused on area with blue flowers over tan speckled background:
(minimum 60-second test)
(minimum 60-second test)

- Arsenic (As): 9,252 +/- 973 ppm
- Barium (Ba): 2,236 +/- 530 ppm
- Chromium (Cr): 1,506 +/- 345 ppm
- Antimony (Sb): 1,055 +/- 197 ppm
- Gold (Au): 499 +/- 182ppm
- Zinc (Zn): 17,200 +/- 1,000 ppm
- Nickel (Ni): 830 +/- 100 ppm
- Iron (Fe): 1,103 +/- 215 ppm
- Titanium (Ti): 14,400 +/- 1,900 ppm
- If a metal is not listed then it was not detected.
With scope focused on area just with tan speckled background:
(minimum 60-second test)
(minimum 60-second test)
- Lead (Pd): 83,000 +/- 3,100 ppm
- Cadmium (Cd): 1,669 +/- 120 ppm
- Barium (Ba): 338 +/- 128 ppm
- Chromium (Cr): 820 +/- 188 ppm
- Antimony (Sb): 268 +/- 57 ppm
- Gold (Au): 734 +/- 293 ppm
- Zinc (Zn): 24,700 +/- 1,000 ppm
- Iron (Fe): 1,563 +/- 265 ppm
- Titanium (Ti): 18,900 +/- 1,100 ppm
- Zirconium (Zr): 2,654 +/- 150 ppm
- Platinum (Pt): 1,084 +/- 287 ppm
- Cobalt (Co): 298 +/- 129 ppm

With scope focused on plain white milk glass of bottom (image above):
(minimum 60-second test)
(minimum 60-second test)
- Lead (Pd): 466 +/- 38 ppm
- Cadmium (Cd): 24 +/- 10 ppm
- Barium (Ba): 172 +/- 67 ppm
- Bromine (Br): 75 +/- 10 ppm
- Zinc (Zn): 72,900 +/- 2,000 ppm
- Iron (Fe): 715 +/- 142 ppm
- Vanadium (V): 117 +/- 50 ppm
- Titanium (Ti): 207 +/- 71 ppm
- If a metal is not listed then it was not detected.
The amount of lead that is considered toxic to children in a newly manufactured item intended specifically for use by children is anything 90 ppm and higher (in the coating.) Vintage dishware is not regulated at all for “total lead content as detectable with an XRF” and neither is modern dishware (yet.) [Isn’t it interesting that it was positive for gold and platinum!] NOTE: The outside paint on many of these vintage Pyrex pieces will also test positive with a reactive agent test (like a LeadCheck swab: http://amzn.to/2DfE3ER affiliate link).
Take away: if you can avoid having vintage Pyrex in your home (especially for functional applications/ daily use), I would highly recommend that.

Thank you for reading and for sharing my posts.
As always, please let me know if you have any questions.

I think I have a set of these. Received as a wedding gift back in 1981.
I didn’t see that you tested them INSIDE the container – where the food is touching the container.
I am wondering if these are safe for me to use – for just food storage in the fridge. I don’t use them in the microwave.
The inside reading is the milk glass reading listed on the post.

I have this exact bowl. I have been leaving water for my cats to drink, in this bowl. I will throw it away and buy stainless.
Thank you for this great information.
Me too I got a set of 3 as a wedding present. Then last year I gave them to my daughter in-law because I never used them anymore. I will have to inform her.
I have 3 mixing bowls – same thing?
I have a Pyrex casserole bowl like the one pictured (Vintage Pyrex Homestead (1976-1980) Design Milk Glass Casserole Dish.), but it has markings on the bottom instead of plain bottom: 473-B Pyrex for oven and microwave, no stovetop or broiler, Corning NY USA 13.
Can you tell from that info if it is lead-free or not? Or is there another source I could go to? Thanks a bunch! I posted your website on my Facebook page for others to see. Thanks for all the work you’re doing. God bless.
If it has the same decorative markings on the outside the outside is leaded. Thank you for sharing about this work!

I have a set of 3 mixing bowls in Vintage Pyrex Homestead Design. Have these mixing bowls been tested? I am interested in knowing if they test for heavy metals on the inside of the bowls.
My bowls have rarely been used as I had preferred the light weight Tupperware mixing bowls… little did I know… even my Spice of Life Corning Ware was unsafe.
