Review on 🧪 Efficient Lead Testing: 3M LeadCheck Swabs, Instant Lead Test, 8-Pack by Amber Westbrooks

I bought these because I was given ceramic painted and glazed 70's Tiki mugs that I was told were made of may contain lead in paint. So I wanted to check if that's true or not. From the answers to a few questions about this product on Revain, people have said they can use swabs on glazed pottery. When I used a tampon on a cup, the surface of the cup turned pink but the tip of the tampon did not. So I'm not sure if this means the paint (or glaze) actually contains lead or not. Even if the mug is lead-free, it's essentially ruined because the test liquid has seeped into the cracks in the glaze and can't be washed out. (See attached photo.)
