When tested with an XRF instrument, this newly-purchased (2019) Miniso simple ceramic mug (in “fashionable” purple) had the following readings:
Purple exterior glaze:
- Lead (Pb): 99 +/- 22 ppm
- Barium (Ba): 1,056 +/ 92 ppm
- TIn (Sn): 903 +/- 49 ppm
- Zinc (Zn): 5,914 +/- 251 ppm
- Copper (Cu): 320 +/- 62 ppm
- Iron (Fe): 856 +/- 201 ppm
- Bismuth (Bi): 66 +/- 21 ppm
- Vanadium (V): 1,923 +/- 117 ppm
- Titanium (Ti): 3,923 +/- 225 ppm
- Zirconium (Zr): 12,600 +/- 400 ppm
- Cobalt (Co): 325 +/- 108 ppm
The level of Lead found in the purple exterior glaze is considered safe by all standards.

White interior glaze (see image above!):
- Zinc (Zn): 23,100 +/- 600 ppm
- Copper (Cu): 136 +/- 40 ppm
- Iron (Fe): 1,070 +/- 157 ppm
- Vanadium (V): 174 +/- 36 ppm
- Titanium (Ti): 337 +/- 55 ppm
- Zirconium (Zr): 2,764 +/- 80 ppm

Silver colored logo stamp on bottom of mug (see image above):
- Lead (Pb): 98 +/- 22 ppm
- Cadmium (Cd): 26 +/- 12 ppm
- Barium (Ba): 1,381 +/ 106 ppm
- TIn (Sn): 1,140 +/- 59 ppm
- Zinc (Zn): 6,007 +/- 256 ppm
- Copper (Cu): 369 +/- 67 ppm
- Iron (Fe): 670 +/- 191 ppm
- Bismuth (Bi): 44 +/- 21 ppm
- Vanadium (V): 1,637 +/- 140 ppm
- Titanium (Ti): 19,300 +/- 900 ppm
- Zirconium (Zr): 15,700 +/- 500 ppm
- Cobalt (Co): 321 +/- 108 ppm
XRF testing was done with a Niton XL3T, in “Consumer Goods” mode – for a minimum of 60 seconds per test, unless otherwise noted. Results are science-based and replicable. Metals not listed were not detected by the XRF in consumer goods mode.
This mug definitely falls in the “Lead-Safe” category of products, just not quite 100% Lead-free. Darn! Still looking for the elusive completely Lead-free purple glazed ceramic mug! (My new quest!) I was happy to see that the white interior of the mug did test 100% Lead-free. If you served me coffee in this mug when visiting your home, I would feel comfortable drinking from it (although, given I have a 100% Lead-free stand for my own kitchen, just on principle, I probably would not choose to have a full set of these in my kitchen.)
That said, I really love this store (Miniso!) — it’s like an Ikea just for small things, and it looks like MOST of the things in the store seem likely to be Lead-free! I will be posting more from this store soon.
As always thank you for reading and for sharing my posts.
Please let me know if you have any questions.
