No one like the smells of ash and dottle, so I have always assumed that my practice -- dumping it into an empty large tobacco tin with a tight lid (preferably one of those with a plastic top), then throwing away the tin when full -- is universal.[/quote]
This is pretty much my approach. If there's one thing I have in excess, it's empty tins of escudo. So I dedicate them as ash trays. I don't throw it away when full though. I just dump on the fire pit when full and use it until the label wears off. Then I grab a new one (new, empty tin).
