What is the purpose of this pipe?
I recently purchased a pipe for “tobacco” smoking. I didnt notice until I got it home however that it was different from any pipe I have ever seen. The base is thick and powder-coated solid blue. The material feels like some kind of metal, or ceramic, as it is tough and heavy. You have a normal looking steel bowl on the top, but then there is another bowl that screws on to the normal bowl. This bowl is made of the same blue material as the pipe, with an inlaid steel bowl thats holding what looks to be a small piece of pumice or something, sitting where you would normally put a screen. This piece is threaded and screws into the regular bowl, so they sit one right atop the other. I was just wondering if this has any special purpose, or if this is anything anybody has heard of. Thanks!
My guess as a long time(over 20 years) pot smoker(mostly pipes btw) that the device U are describing would be some sort of vaporizer, which allows the heat from the flame 2 release the active components from the vegetable matter without allowing combustion 2 occur. That would be the least harmful way 2 get the medicinal effects of the “tobacco” while avoiding the lung stress brought on by inhaling smoke.
