Yup.
The bowl piece is called a nail.
It is used for doing "dabs" of BHO.
BHO is butane extracted hash oil.
The bowl is made of either Titanium or pure Quartz Crystal.
You use a butane torch to heat the "nail/bowl" until it turns red hot.
Then you drop a piece of BHO into the bowl, and inhale.
The waterpipe piece itself is special too. It's called an "Oil Rig".
It has a number of honeycomb perculators at the bottom to super filter the smoke, as it is extremely dense and heavy on the lungs.
It is the closest thing to doing SC's I have ever done.
I have seen people have panic attacks from one hit.
I have also seen people turn white and pass out form doing a hit.
If people are interested in this, I can post a step by step (with pics) how-to.
I love smoking this stuff, but it is really harsh on your lungs. Expensive too.
My friends BHO regularily tests at over 70% THC
You need to choose your "Rig"....
My favorite ones are by Mobius Glassworks. Here is a link to a company that carries "Oil Rigs", they carry Mobius Glassworks:
