I smoke my meerschaum pipes 80% of the time. With 20 of them in my collection it takes a while to get them all rotated through, but I eventually do. It also takes longer to color them, but I smoke them for the cool dry smoke and natural flavor of the tobacco.
If you don't own a meerschaum pipe I definitely recommend that you try one. I absolutely love mine.
My last two meerschaums. The first is an early 1950 Kirsten Transition pipe. I have two briar bowls, but keep the meerschaum bowl on it because I use it for sampling new tobacco blends.
The other one is what I call a Sultan Saxophone. I found it at a flea market, unsmoked for $10. The first time I smoke it a hairline crack appeared around the bottom of the turban. I smoked it one more time and applied superglue to the crack with a toothpick. Now I just leave it on the shelf as a piece of art.
