Is this actually necessary.
I mean this idea that a new pipe should be rested after the first bowl or whatever.
Personally I've never done anything like that and I've never had an issue.
I've always taken a new pipe out of the box and packed it up and smoked it.
And if I like it, I smoke it all day for several days till I get a bit tired of it.
Personally I've never had any issues.
When briar burls are harvested they are the wet, green wood of a living shrub.
They must be boiled or steamed or soaked to remove foul tasting sap, and to cure and season the briar.
Then after that, they must be either kiln dried or left to dry out naturally. The final maker may boil or cure the blocks again.
Richard Lee who made Pipes by Lee figured out, and advertised, some method to further cure his briar that makes a Lee sweet to break in. It’s still needs breaking in, but it’s a pleasant break in.
I buy a lot of used pipes and most were not smoked all the way down to the air hole. When I smoke them down to the last ember, I can taste a little whiff of briar in pipes that are over 75 years old.
I think what break in does is put the last, final cure and seasoning to the briar.
There are pipes, in my experience Danish freehands the worst, that must have not been very long cured, seasoned and aged. But after about thirty smokes almost all pipes are fully broken in.
I’ve used a dab of honey to break in new pipes for fifty years. It doesn’t hurt one, I promise.
A good pipe, can be smoked from the box and it’s a pleasant experience.
Some need more help.
