It works. I'm disappointed that it was this easy, but it works. I feel like the meerschaum mafia is on their way to my house now that I'm disclosing this.
Put the meer in a glass jar. Smoke another pipe. Blow smoke into the jar, seal the lid. Repeat several times a day. After 2 days my throwaway meer is more colored than the ones I won't use this cheat code to color. I have had my Tekin for a month and smoked it every day, but it has less color than the meer I have colored in this experiment. This is cheating. But I know there are some coloring-freaks out there. Well, this is it. The cheat code to coloring meerschaum. I'm sorry.
I've seen YT video's of that trick. I've tried it and didn't really notice any difference. I would take the stem off the pipe and just put the stummel in the jar. After about 45 minutes or so the smoke will have dissipated out of the jar, and I would blow more smoke in, and did this several times throughout the day before putting the pipe back on the shelf. Over time I didn't see any real change in the color.
Will it work, in theory yes, if you put enough smoke in the jar and do it multiple times, then yes, the pipe will absorb some of the smoke and it will eventually add to the color.
For those that want to color your pipes quickly...
Remember, even if you have two identical pipes, made by the same carver, and you smoked them equally with the same tobacco, both pipes will color differently. The key factor is the quality of the meerschaum the pipe is made from. All meerschaum will color differently. Other factors are the frequency of smoking, and the tobacco that is being smoked in it. The best way to color it is to just smoke it.
I've seen pipes that are smoked like a freight train, and they have some color, and I've seen some that are smoked much less but have more color to them. It comes back to the main factor being the quality of the meerschaum.
