It's a slow process to season a new pipe. Gradually building up the burn on the inside of the bowl in a nice ordered manner to prevent the wooden object that holds burning tobacco from burning in and of itself.

I got this Outlaw pipe after my favourite pipe broke and I'm loving the size, weight and texture. Truly a sensual pleasure.
