Can an old pipe knock on an ashtray?

There is no need to pour ash when lifting the bucket, which is helpful to the low temperature stewing of tobacco. If the bucket bowl is deep (above 40MM) and can be sucked to half, tilt the tube and tap it gently with your hand to pour out some ash. Every time you smoke for a while, a layer of soot will accumulate in your pipe. If it is not too thick, you can press it down slightly with a pressure bar, flatten it, and then ignite it evenly. When the ash accumulates to a certain amount, which hinders combustion, it can be carefully removed with a small spoon, or the ash can be loosened and gently shaken off. After smoking, you can knock the ash out of the cork. If it is a Heather tube, don't rush to clean the bucket and bowl, and then clean it after the tube is completely cooled.
