Grav Labs, hands down are the masters of glass, scientific producers of glass if you will. A global reputation that is hard to surpass. Built to last, highly functional and as gorgeous as glass can get. Those in the know only and always use Grav glass. When Grav makes a water pipe/dab rig/glass pipe they know what they are doing. Built strong for a smooth and easy session. Oh, and so they don’t break easily either. Beautiful enough to display anywhere in your home, if that’s how you do things.\


Sometimes you just feel the need to style up your herbal ritual with the addition of a new flower bowl or maybe you are a little clumsy and broke yours! Either way I try to stock a wide variety of flower bowls to cover as many needs as possible. The Caldera Bowl has been designed with style in mind as well as high functionality. Having never heard the word caldera before, off I went to do a little research and here it is. A volcano erupts and magma is ejected from its chamber. This chamber empties out and you are left with a caldera, a form of empty space.

No magma involved but I would describe the space within the bowl to be wide but not deep. I like this feature as it enables you to more evenly light your herbal material within.  According to Grav (I have not verified) you can fit 0.5g of flower inside.
Super durable Borosilicate glass has been used but as always, I recommend tender loving care as it still is glass! A frosted port comes standard on all Grav bowls, helping to create an airtight fit. The connection is 14mm and is male.

Measuring: 4.5cms tall and almost 3cms at its widest.
