3) When the records are pressed, do you use all of the ashes, or just some?

It depends how involved the customer wants to be in their record! Not much is required. Obviously, any foreign matter in a vinyl would normally be the last thing you want. Of course a little ash will compromise the sound quality and cause pops and crackles, but that is the point and proof that you’re in the groove. For these reasons very little of the total remains will be used in each record.
