I had this pipe coming in the post today. This is what they called "Cultured Meerschaum," that is, this is neither "block" nor "pressed" meerschaum. Don't ask me how they managed to do it (this is a trade secret), but, basically, they just cultivate/grow sepiolite out of its chemical components/constituents. The final product seems to smoke as good as block meerschaum, will discolour as time passes by, and they claim it takes up to 2 years for the compound to set in and fully form as smokable meerschaum. They claim the came up with this idea due to block meerschaum being prohibited for exportation purposes in Austria. It seems that by doing this they save money on the production line without compromising on quality. My only complaint is that the bowl seems to be quite big (23mm) but I have tested it with loose tobacco and it seems to smoke perfectly fine. If you like flake tobacco like I do, just look for smaller bowls. I highly recommend these pipes.
