There is no hard fast rule when it comes to pipes, just best practice guide lines to follow.
Since you are asking about this, then I highly recommend you going slower, because without experience, you’re not going to know, whether or not, if you are pushing the pipe to hard in the beginning.
Because when you said ‘One Hour’, that’s pretty fast. It’s also not about the fire/heat, but the moisture, and not building a lot either in a new pipe.
Do you know the Chamber Depth specs on the pipe? Taking a best guess here, that looks like around 40mm.
Now, this is just my own personal take, again, I believe in the slower/easier is always better, because there’s less chance of issues, but with briar being so resilient, issues are rare, but it’s still good to go easy on a new pipe.
My best guess, looking at the pics, you should be smoking a bowl in 4-6 hours, not 1.
As I said before.... ‘Slow’
A lot of people smoke their pipes to the bottom, but you also want to make sure you don’t char it at the bottom, or char the air way. Stop smoking when you think it’s 1/4 at the bottom. After smoking, you can run a pipe cleaner through it dipped in Everclear, high proof like 150 is better for cleaning.
I share these style of methods, because unless your rich, or don’t care, someday, you buy a $500-$1000 pipe, you will probably want to know how to really take care of it, to give you the ultimate in smoking.
