Thanks for the inspiration, Betty! I just finished a set of my own! Pleasure to go without spillage! There is a business opportunity, right there .
I used a small wood screw to attach the aluminum tube part of Brigham filters to the cork, to use as a handle.
Oh, and I used wine corks instead of hardwood, because they are "squishy" and thus will expand and contract with the warm briar - so I don't risk cracking the pipe.
I also carbonized the undersides with the same stuff that is used to coat pipe bowls, to make them "burn resistant", just in case the tobacco is not fully out when I cork it
Exactly what I did with a bowl of MB Golden Extra. Picked it up this morning and I could continue where I left of. The other use cases would be to readily pack a pipe in the morning, stash it away for later in the day, or when taking a pipe to town/party/... pack it, cork it, put it in jacket and off ya go, without the need to carry a tobacco pouch, or finding your pockets full of crap and the pipe empty.So the idea is that you fill a bowl, start smoking it, but not finish so you cork er up, and in the AM, take off the cork and its "as if" you have a fresh bowl?
