I was looking at the Meerschaum Market web site (anyone ordered from there?) and I can see what a difference in price it makes for the pipe to be carved by a master.
Yeah meerschaum market is a great site. I have not yet made a purchase there, but I've looked it over quite a bit. They've got a list of master carvers, and a lot of IMP meers that are just fabulous.
I try not to look at all the various meer sales points too often because it's so tempting.
Regarding the handling issue, as with so many other things pipe related, it's strictly a personal preference. And by all means, if one is of the mindset to handle it as carefully as Warren described in an effort to eliminate any interference in the coloring process, that is commendable. But it's certainly not mandatory.
A lot of people are under the impression that meers must be handled that way so they just don't want to deal with it. Honestly, if I had to handle my meers like that I probably wouldn't have any. I'm not that patient and I'm just not that concerned with how they look.
After a sufficient number of years have gone by I'll see how the coloring looks...until then I'll continue to handle them just like my briars. In fact they're lower maintenance than briars imo. That's one of the things I like about them.
EDIT: the only thing I do differently than with the briars is wipe them off gently with a cotton cloth after I'm finished smoking.
