BT, They have testers that are a swab you rub on the item and see the color change. It should work on your pots and pans. Due to work I had to be certified in lead abatement and have been since 2010. The swabs you should be able to get at your box store. They give you an indication of the presence of lead but if you want to know the amounts you'll need to send them to a lab. If your home was built after 1978 you don't have to test for lead because it's use was stopped before that time.
Now as to your other problem I suggest you be a really nice guy and buy your tradesperson's this product. You'll save yourself and others the horror of the problem that crack kills.
