p.s Don't try coating cymbals with clay - they go muted!
And Zildjian cymbals (the best ones) aren't brass:
"Our cast Bronze cymbals are forged from ingots of secret
Zildjian alloy; then rolled, shaped, hammered and lathed
into instruments of unparalleled projection, clarity, and
durability. Each possess a unique musical voice that can
last a lifetime and values with age."
