Most decorated ceramics found at a thrift store have lead in the ink. The kit tells you which ones do, in under a minute, so you can keep the rest.

The problem
Lead-bearing inks were the industry standard for decorated dishware from the 1950s through the 1980s. Pyrex, Anchor Hocking, Corelle, every department-store brand. You cannot tell by looking. The decoration sits on the outside of the bowl, against the food. The leaching is heaviest where the paint meets acid: tomato sauce, citrus, vinegar, coffee, soda.
The bowl in the reel was not unusual. It was a normal piece from a normal kitchen. That is the whole point.

2019 · why I built this
In 2019, when I started making blood testing kits, I had no idea what I was doing. I just knew I was making a better product available at a better price.
When I started talking to the people who were buying them, I found out most of them were buying because their kid had already been exposed to lead. The blood test was confirming damage that was already done.
Once I found out about Fluoro-Spec, I dedicated a lot of time and effort to making that a thing of the past. Nobody needs to be exposed to lead when it's this easy to find it in the environment first.
The mechanism
Same reagent academic labs use to grow perovskite quantum dots, in a bottle that fits in a drawer.
A drop or a quick spray. Methylammonium bromide in isopropanol. Wipes off, does not etch glass or glaze.
The reagent finds surface lead and forms perovskite quantum dots locked to the painted decoration.
Lead glows bright green at the exact shape of the paint. No lead, no glow. Yes-or-no on the surface you actually touch.
Keep what is clean. Bag what is hot. Move on with your day.

If you actually plan to test the whole house
Two drip bottles. Two spray bottles. Two flashlights. Two color cards. Each bottle is ~120 tests, so the Double Kit covers around 480 surfaces. The per-test math is roughly thirteen cents.
FLUORO30 pre-applied. About $34 off the listed kit. Compared to mailing samples to a lab at $80 each, the kit pays itself back on the first hot bowl you find.

The deal
Sixty days. No return shipping. No questions. If the chemistry is real and the kit found nothing in your house, that is the best news. We do not need it back to feel ok about that.
No. The reagent wipes off with a paper towel. It does not etch glass, glaze, paint, or metal. We use it on heirloom plates, baby bottles, walls, and soil.
The drip puts a tiny amount of reagent on one specific spot. The painted edge of a mug, the rim of a bowl, a glaze line. The spray covers a wide area in one pass. Window sills, garden soil, tile, faucets. Most houses need both.
Not every piece, but a lot of decorated Pyrex from the 1950s through the 1980s used lead in the printed pattern. The bowl in the reel is one of those. Anchor Hocking, Fire-King, Corelle, and a hundred other brands of the era are in the same category. Test yours instead of guessing.
Most surfaces in most houses do not glow. That is the answer you usually want. The kit is reusable. Keep it under the sink for the next garage-sale find, the next imported mug, the next painted toy.
It picks up the surface lead that actually leaches into food at the level a child can dose from. It is not a lab assay. It is a fast yes-or-no on the surface you touch. For exact ppb, the lot data and FDA-IRL dose calculator on this site are downstream tools.
