Introduction: Tamara Rubin is an independent advocate for consumer goods safety, and she is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017.She uses high-precision XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for metallic contaminants – including Lead, Cadmium, Mercury and Arsenic.
The full XRF test results of the small platepicturedare below (so please scroll down). Here are links to some additional reading that may be of interest, based on your interest in the test results of this item:

#FunFact
The owner of this piece told me that she personally purchased it in Tokyo in 1993 or 1994, and these have been her everyday dishes ever since. #FunFact: Japanese china made in Japan for sale in the Japanese domestic marketis – more often than not – Lead-free on the food surface of the dish. Conversely, china made in Japan for exportsale in the American market] often tests positive for Lead (often at very high levels) on the food surface!!!! I love discovering these beautiful decorative heirlooms in people’s homes – specifically Japanese-made vintage pieces with Lead-free food surfaces (which I find most often in the homes of first- or second-generation Japanese-American families [i.e. the grandparents or parents were born in Japan and brought the dishes with them when they moved to the United States].)
Important Note:
- If a piece has the words “Made In Japan” written on the back – in English – that means it was most likely made for sale in the American market, and therefore is more likely to test positive for high levels of Lead (when using precision XRF technology.)
- When you look through the “Japanese China” category here on my blog, you can clearly see the different range of Japanese china. With some education it becomes fairly easy to tell — based on design, product qualities, and color usage — which items are true Japanese made for the Japanese domestic market and which aremanufactured to export and sell in America. Start by scrolling through the Japanese China category here on this link.
Stay Safe Out There!
A quick note from Tamara
Hey readers – I hope you are staying well out there with all that is going on in the world right now. I’m hanging out mostly at home with my children – and have been doing so for about 10 days now. I pulled them out of school over a week ago – just to be safe. Each of my three youngest sons have compromised immune systems (which manifests in different ways for each of them), due to having been Lead-poisoned as babies.
In between kid-wrangling I am working hard to publish literally HUNDREDS of new posts (with test results for various consumer goods I have tested over the past couple of years, but have not yet had a moment to report on!). These posts have created a backlog in my system for more than a year now – and it’s actually nice to have a *break* with some time to catch up! To make this happen as quickly as possible, I am (as with this post) simply posting the images and the test results – without a lot of additional information. [Do not worry — I will continue to update them with more information as I get caught up and begin to have the time!]
For those new to my website, please check out the menu in the header of the website for more information about how I test things (and my background, etc.) On each post you can also click on any of the keyword tabs at the top of the post to find more items in that category. Here’s the post discussing the type of testing I do, and the specific instrument I use to detect, analyze and confirm metals content, and ultimately produce the resultant data for each item reported here – link.
Please Note: Test results reported below are science-based, accurate, and replicable. Test results reported here are from tests that were done for a minimum of 60 seconds each, and repeated multiple times, to confirm the results. As with all the testing reported here on my blog, a freshly-calibrated high-precision XRF instrument testing in Consumer Goods mode was used to test the item pictured here.
As always, please let me know if you have any questions.
Thank you for reading and for sharing my posts!

Test results for the vintage small Sanyo plate, made in Japanpictured on this post:
Food Surface – focus on blue:
- Barium (Ba): 3,298 +/- 389 ppm
- Copper (Cu): 82 +/- 31 ppm
- Nickel (Ni): 66 +/- 35 ppm
- Iron (Fe): 1,471 +/- 134 ppm
- Bismuth (Bi): 60 +/- 16 ppm
- No tests were positive for Lead on food surface.
Back of dish – focus on white:
- Lead (Pb): 30 +/- 15 ppm
- Barium (Ba): 4,130 +/- 413 ppm
- Iron (Fe): 1,654 +/- 160 ppm
- Bismuth (Bi): 50 +/- 18 ppm
- 4 of 6 tests on back were negative for Lead and two were positive at similar levels – similar to the level noted above.
