Carnuba Wax inside stem

I recommend you give the pipe to me to avoid danger.
Barring that, I personally wouldn't get to concerned. A pipe cleaner will catch most of it. I don't imagine you'll die. Maybe just lose your eyesight or have an appendage fall off or something.

Seriously though I'm sure I get carnuba on the business end of the stem and maybe even in the slot, and I've never noticed any problems.
On a related side note...man that carnuba smells good when it gets warmed up on a buffing wheel.

Carnauba is a harmless, natural substance made from palm leaves, which is why we use it (along with the fact that it just dulls over time, as opposed to flaking). It is also used in cosmetics etc. and as a thickening agent in food. You could probably chew on the block if you wanted to do so.

Definitely nothing to be worried about.
Pure carnauba wax is basically inert. It is sometimes used as a coating on dental floss, candy, and pharmaceutical caplets/tablets.
When mixed with other chemicals to create car waxes and such, it may be a different story....
FWIW...here is a link to Wikipedia (the all knowing, and only true source of information) on the subject.

Nahh Prefontane... you don't lack the skill. Here's how I know.....I can do it. By definition then anyone can. Easy peasy. Just hold on tight and be smart about the angles you hold the pipe at against the wheel. Otherwise it's like feeding the pipe into a pitching machine. I know...I've seen me do it.

Don't listen to these fools carnuba is very dangerous you shoud give it to jonesing or myself for proper disposal.

Lol Jonesing, I can just picture pipes flying everywhere while a mad piper is trying to buff his pipes.

Working with a buffing wheel it isn't IF it will grab something and shoot it across the room. It's WHEN!

I've had pipes snatched out of my hand and fluing across the room at speeds "faster than a speeding bullit." Keep the object below the centerline of the wheel and don't let an edge come in contact with the wheel. Although some recommend not inserting a finger in the bowl when buffing, I do it regurlary.

I love it when amatuers give advice. Its always filled with half truths and non-sense. Buffing wheels are supposed to shoot pipes. Its how we know there is the right amount of wax on the pipe. Buff, buff, buff, shoot. Buff, buff, buff, shoot. Enough wax = no scratches on pipe when smacked against the wall or the floor by the buffing wheel. Not enough wax = scratches when smacked against the wall or the floor by the buffing wheel. If after launching your pipe with the buffing wheel, you find scratches, just buff off the scratches and put on more wax. Its natures way of telling you that you need more wax. Why do you think car waxes include carnuba wax? Its to help protect the car in the event of a crash. Did you ever see a nicely waxed crashed car? Nope. Because those cars just drove away unscathed. You only ever see dirty cars in car crashes. Not enough wax.
What's next? Telling people they shouldn't wear neck ties while they use the buffer?

You mean you're NOT supposed to wear a tie when buffing? I've done it for years. Mind you I have the shiniest tie in the whole of the UK and for some reason my collar size has reduced by 2 inches and my eyes bulge!
