Thank you for the information—helpful and enlightening.I own a business in aerospace metals.
The cymbal must contain a certain amount of heavy metals, such as chromium, nickel, or cadmium.
Depending on the region and the attorneys they might either have to or want to make that fact known
The forms of metal in a cymbal are obviously non-hazardous, they are not ionized and dissolved in water.
It’s overkill but some might say better safe than sorry
