Check out this post, I give quite a bit of information on the Morta pipes I owned at that time, it has since grown.
Details man, details, I'd have nabbed that in two shakes of a Weimaraner's tail!
Morta comes in quite a few colors, here is a chart, it is not complete but as you can see age (how long it has been submerged) and what kind of soup it was in is the determining factors.
Thanks for the chart fish...
Werebear..Morta is semi-petrified wood..also called bog oak...it is a unique material used to makes pipes...similar smoking qualities as meerschaum but less fragile.
The Copper color is natural, it's not as old as the black...it's very rare to find copper and gold..black is the most common...as the chart shows, it ranges in age from 1000 to 8000 years old...only a few pipe carvers in the world work with Morta..because of the density of the material, and rareness of good quality blocks available to make a pipe.
Very specific "bog" conditions are required to preserve the wood so it doesn't rot to allow it to turn into Morta and it's only found in a few places in the world, (France, Croatia...etc.)
That's a nice looking pipe. A pipe maker I know has made several morta pipes out of 6000 old morta and he's stated that its very tricky as it can be difficult to carve. Enjoy the pipe... she's a beauty.
