the one I smoke the most is coloring fairly nicely and at a good rate. I just read Russ's article on breaking in pipes where he mentioned to blow smoke through the pipe. I may give that a try.
I have had mine since February it was an estate I got from dimm but it had no color showing. After I started applying bees wax the color screamed right out. This is from about 2 weeks ago.
I like that pipe toker. I have one, I just took a before pic about 2 weeks ago, and I have been smoking it and it shows lots of difference, I was planning on posting the pics after it colored much more
