This blog (and YouTube Video) is to give some feedback on my experiment on the layer of cake (aka carbon layer) inside the bowl of your pipe.
A sufficient layer of cake in the bowl of your briar pipes are essential for the preservation as well as the coolness of the smoke. The general suggestion is to build up a layer of "a dime". Of course, like everything in the pipe world, some believe in less and others in more. And so I've tried some suggestions.
