The hobbit pipe has a builtin cigarette filter holder and a fitted soapstone stand (I dont even smoke but found it cool haha)
The vaporizer pipe has these big slits at the bottom and holes above, meant to reduce heat. It can be heated with a flame and steams the herbs inside, no burning, ever!
But you need propane or some other clean gas, candles and butane have nasty particulates and tar inside (the bottom literally gets black) that you dont want to inhale ;)
Beautiful work, but inhaling the silica, talc, and magnesium at high temp is probably not advisable for your lungs. I know soapstone has been used for pipes and cookware for tens of thousands of years, but please be safe.
No worries, it is only decoration nowadays XD
