Is the stem acrylic or rubber?
Boiling water can cause bubbles to appear in acrylic (been there, done it), but on rubber it can leave you some serious oxidation. Absent a heat gun, a candle or the flame on a gas stove works just fine. Just be sure to move the stem in and out of the heat directly above the flame and take your time.

what I have done when I needed to bend a stem is this: I placed a pipe cleaner in the stem, then used a hair dryer, somehow my wife's gives out a very very hot air, after maybe 20-30 seconds, the stem is pliable enough to do the necessary adjustements. if you try, tell me how it went. Cheers.
Don't leave us hanging, man. How about a pic of this unique pipe? or maybe when you've finished the adjustments.
I've always used a lighter. Just hold the stem several inches above the flame, and turn the stem to evenly distribute the heat. Don't rush, and when you achieve the desired shape, dip it in cold water to set the shape.
I've done all three, boiling water, flame and a heat gun. I like the control the heat gun gives you, so that is my preference. Flame is only for the most fool hardy!
I did one with the flame, it's risky but certainly works. A heat gun is about $12 and has far less risk, so I went that route. To each his own!
I tried a heat gun a few times, but seemed like it heated too much of the stem for precision bending.
I use a flame from a lighter to bend cob stems and a hair dryer on high heat to bend acrylics & vulcanites.
Bo Nordh used an alcohol lamp or candle. Not recommended for the inexperienced, though.
Hot water is messy, slow, and does indeed turn some vulcanite a lovely, deep shade of olive-puke greenbrown. Not recommended for anyone.
Oven-baked pans of sand or salt are a complete PITA for one stem. Avoid except for mass production.
A paint stripper type hot air gun (on a low setting if adjustable) is the best choice by a considerable margin. Just wear gloves, DO NOT LEAVE FOCUSED ON ONE SPOT, and test the stem for "bendiness" frequently until you get a feel for it.

" I like the boiling water method (for Vulcanite) because the temp is controlled.
That will instantly turn a vulcanite/ebonite stem green."
I've never seen any green. Sometimes a bit of brown oxidation or a whitish haze, both easily remedied with 800-grit cloth and a bit of elbow grease.
