Lead Testing
How-To
Test for Lead Contamination in Ceramic Tile
Ceramic tiles are often decorated with lead glazes and fired in a kiln. Improper firing can allow the lead to leach from the glazes. In addition, surface abrasion from “normal” wear and tear can start to break down the glaze, which also allows lead to start leaching from the surface.
Supplies
- LeadCheck® Household Lead Test Kit
- Object to be tested for lead
Steps
- Activate a LeadCheck® Swab according to the instructions.
- Gently squeeze the swab to force some of the amber LeadCheck® dye onto the tile surface.
- While continuing to squeeze gently, run the swab tip over the tile surface for 30 seconds.
- If a pink or red color appears on the swab tip or the tile surface, potentially hazardous levels of lead are leaching from the surface.
If lead is identified in your home, then use these "lead safe practices" :
- Get children tested even if they appear healthy.
- Wash children’s hands, bottles, pacifiers, and toys often.
- Regularly clean floors, window sills, and other surfaces.
- Replace mini-blinds that test positive.
- Avoid using positively-tested dishes on a regular basis.
- Avoid using dishes that test positive for storage or for serving acidic foods.
- Don’t leave toys that may contain lead in the sun.
- Never sand lead paint.
