I noticed droppers sold at a popular store are labeled "Not for food use". What about them would make them unsafe for food use? They are cobalt glass droppers.
From some searches it seems possibly related to the lead content in the glass. But there is not a lot of information on this.
How do I know if other glass vials, droppers, jars are safe?
