Lead Testing
How-To
Test for Lead Contamination in Brass
Brass is a metal alloy primarily comprised of copper, tin, and varying amounts of lead. Antique brass may contain very high levels of lead, while brass manufactured since 1986 usually contains less that 7-8% lead. In both instances, the lead may leach. Antique brass items such as candlesticks, key chains, or faucets may leave a lead residue on the hand when touched.
Supplies
- LeadCheck® Household Lead Test Kit
- Object to be tested for lead
Steps
- Clean the surface with a household cleaner, rinse and dry.
- Activate the LeadCheck® Swab according to the directions.
- While squeezing the Swab to force some of the yellow liquid out onto the brass surface, gently dab the Swab tip over a small area of the brass for about 10 seconds. DO NOT rub the area with the Swab.
- If pink or red color is observed, the brass contains leachable lead.
A purple color on the Swab indicates that the tin and the swab were probably rubbed too hard on the brass surface. Repeat the test, keeping in mind to “gently tap or dab” the LeadCheck® reagent over the brass 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.
