Beautiful pipe. Congrats! I'm sure I'll be hammered for saying this but with a few of my pipes, I did the 1/4 bowl a few times, then 1/2 bowls, etc, etc..Then with others, I filled the pipe right off the bat and smoked the first few bowls really slow, letting it cool, then re-lighting now and then. No difference what's so ever. The pipe is meant to be smoked and if you start off slow throught he bowl, I think you're fine. If the pipe only last's for 50 years instead of 100, I'm not worried about it. Just my opinion. I think the problem is that some people smoke like frieght trains so the bowl gets way too hot the first few smokes, not good then.
