“Tamara, tell me more about this testing…”
Testing is done with the same instrumentation used by the Consumer Product Safety Commission to test consumer goods for Lead (and other toxicants), when screening for safety (including screening items intended for use by children to make sure they fall within acceptable levels.) All tests are done for a minimum of 60 seconds unless otherwise noted. Tests are repeated multiple times on each component to confirm the results. Test results are science-based, accurate and replicable.
Some additional reading that may be of interest:
- More products from Hobby Lobby that I have tested.
- More Cabinet Knobs that I have tested.
- More Drawer Pulls that I have tested.
- More floral patterned items I have tested (if that’s your jam!)
- A short video that shows you how to efficiently navigate the more than 2,700 posts and pages of information on this website (please definitely watch this if you have not yet, it will help you find all the things!)

As always, please let me know if you have any questions. With 1.165 Million unique readers in 2020 alone I am not always able to answer each and every question personally, but I do try. Thank you.
