Just make sure your hands are clean, and move the pipe around in your hands while smoking. Nothing crazy or uncomfortable, just don't hold it in the identical place all the time.
Ive been smoking Meerschaum pipes for many years with no issues.
Also, keeping it waxed with white beeswax makes a HUGE difference. It helps the pipe color evenly and, sinse there is a layer of wax, it keeps your hand oils off the pipe.....for the most part.
I cannot even tell you how important the white beeswax is.
I learned this years ago from some "expert" Meer smokers on the old Smokers Forums. I wax my pipes after about every 20 smokes.
It seems excessive, but it pays in the end.
You end up with a nice EVEN caramel golden color and not a darker, or black color.
Waxing is very easy and very fast. I get a pipe done in ten minutes or less.
I melt the wax in a small tin with a candle flame....this is the perfect amount of heat. Then I use a Q-tip to wipe the wax all over the pipe......it will dry chunky. Then use a hair dryer to heat the waxed pipe, and rotate the pipe by the stem until the wax spreads all over the pipe evenly, or drips off.......use a lot of wax, it comes off easy. Then I rub the pipe with a soft cloth.....bam, done....easy peasy.
I even do my lattice pipes, the wax melts off and out of the holes but leaves a thin layer of wax.
You can use yellow beeswax, but it will leave a yellow color on your pipe and make the "natural" coloring look odd.
This is how I was told to do this procedure and its worked fantastic.
