About a year and half ago, my best friend brought me back this pipe from his honeymoon in Merida, Yucatan, Mexico. Since that time, I've tried to research it and I haven't found anything on pipes like these or found any pictures that resemble it. Now that I'm smoking pipes, I'd really like to fire it up. Here's the draft hole at the end of the stem: I can put a pipe cleaner through it, but the draft hole in the bowl doesn't seem to be centered: Also, I'm concerned that the glaze or the clay itself might be toxic. Anyone have any experience with pipes like these? Should I look and not smoke? Thanks.
