These millimeter sizes are in reference to the glass slide measurement for the standard non-glass-on-glass product they are describing.


These millimeter sizes are in reference to the ground joint on the glass-on-glass products they are describing. The most common industry sizes are 10mm, 14mm and 18mm, which will occasionally be described as 19mm. These are actually the same size, at 18.8mm, and when listed can be rounded up or down for clarity’s sake as long as the rounding is consistent.

Ash Catcher

These are water pipe or bong attachments that help to prevent the accumulation of resin at the bottom of the piece in question. This provides an additional level of filtration that leads to a cleaner, smoother smoke.


Also called a water pipe, this is a large pipe that holds water for filtration. Unlike a bubbler or handheld piece containing water, a bong is usually much larger and consists of a tube mouthpiece that your lips go inside rather than around, such as with a handheld bubbler. Bongs can come in a variety of shapes and sizes and typically consist of a tube, downstem and bowl. Most commonly used with flowers however, can be converted to a dab rig by replacing the bowl with a nail! (Usually 45 degree)


This is the bowl-shaped area of a given pipe where herb is inserted. Bowls usually have a single hole at the bottom to allow airflow for your smoke; however, some bowls use multiple holes or even built-in screens.


A hand pipe that can hold water, much like a miniature bong. Bubblers feature a downstem that is usually fixed on the pipe that filters your smoke through water before inhalation.


A small hole found on glass hand pipes and some acrylic pipes. The carb is covered by the thumb or finger while inhaling to build smoke inside the pipe; releasing the carb releases the smoke in turn and allows for easy inhalation. Sometimes referred to as a “power hitter.”

Carb Cap

A device used for dabbing. Usually used with domeless nails, the carb cap is placed over the nail, pressurizing the oil within and causing it to spread over the surface. This, in turn, helps to vaporize waxes that would ordinarily be wasted.


A dry pipe that resembles a larger, glass one-hitter. Consists of a small, straight pipe without a carb.


A dab is a small portion of wax used to smoke on dab rigs, usually large enough for one hit. Dabbing is the act of smoking this dab.


A tool used for smoking dabs. It is usually a 2’”-5” metal or glass piece that has at least one pointed tip. There is a large variety of dabbers and tips which all serve different functions

Dab Rig

Much the same function and design as a water pipe or bong, but used for smoking concentrates or waxes instead of herb. Dab rigs will usually consist of a male joint with a nail and carb cap. Most can generally be converted to a flower water pipe simply by replacing the nail with a bowl!


Diffusion is the act of water passing through a percolator to create small bubbles in the water, creating a cooler and smoother hit. A “diffused” product such as a downstem is one that diffuses the hit in this manner.


Portion of the pipe that the smoke travels through from the bowl into the water; present in most bongs and water pipes. These come in a variety of lengths and can be easily replaced on most pipes.


Portable box used to store tobacco or herbs. Many feature a slot for one-hitters to allow for a quick smoke.


Term describing a joint or connection to a glass on a glass pipe. Use your imagination.


Slang for dry herb. For example, a “flower bowl” would be a bowl used to smoke dry herbs.


Glass blowing technique that uses gold or silver flakes in the glass to change its color when placed on different surfaces or heated at different temperatures. “Gold fumed” pipes tend to be yellowish before color change, whereas “silver fumed” are more typically pinkish.

Heady Glass

Slang for high-quality pipes, usually hand-blown, made with advanced technology, and often in a limited run.


Sometimes referred to as a “bat,” this is a cigarette-sized pipe with no carb that fits into a dugout for quick, discreet smokes. One-hitters are frequently made from glass, quartz or metal.


An additional filtration mechanism in bongs and water pipes that allows for a smoother, cleaner hit. The most common styles of percolator are inline, showerhead, barrel and tree shapes.


A type of glass used to make domeless nails, bats and other accessories. Quartz is more fragile than Pyrex, but can withstand higher temperatures without breaking.


A component of a bong or water pipe that brings the water back down to the bottom of the pipe when it would ordinarily travel up the mouthpiece. This creates a better flow than most standard water pipes.


Also called “wig-wags,” this is a glassblowing technique that creates colorful spirals in the final design.


A technique used on glass pieces that takes layers off the surface to engrave a logo or design. This is done by literally blasting sand onto the pipe around a stencil, hence the name.


A pipe named for its similarity in appearance to Sherlock Holmes’ hook-style pipe. Any piece with a bowl that drops down and sits lower than the mouthpiece may be considered a Sherlock.


More commonly called a “bowl,” this refers to the part of the pipe or bong that sits in the downstem where the herb is packed. Slides are usually Glass-on-Glass but can also be 9mm or 12mm slides with a rubber o-ring.


A common hand pipe with a bowl and carb. Aptly named for the shape of the pipe. Sits like a “spoon” with a hollowed-out end.


Also called a Bong, this is a large pipe that holds water for filtration. Unlike a bubbler or handheld piece containing water. Water Pipes can come in a variety of shapes and sizes and typically consist of a tube, downstem and bowl.
