2" 18mm Female Black & Slyme Triangle Bowl - The Joint Runs The Other Way

Read the word female before anything else. Most flower bowls are male: they drop into a socket. This one is the reverse. The joint is on the inside, so it slides down over a male stem. Get that backwards and the glass will not go together no matter how patiently you push.

Female bowls exist because not every pipe is built the same way, and we get asked about this weekly. Some designs put the male end on the pipe and expect the bowl to sit over it. Owners of those pieces spend a lot of time scrolling past bowls that will never fit them, which is exactly why we keep a few female options on the shelf.

The triangle is not decoration for its own sake, whatever we might have assumed at first. Flat faces stop a bowl rolling off a table when you set it down mid session, and they give your fingertips a defined edge to hold instead of a smooth curve. Anyone who has watched a round bowl roll toward the edge of a coffee table understands the appeal.

Black and slyme is a pairing we think holds up. Slyme green reads differently depending on what is behind it, and the black gives it a hard border to sit against. Because both colours are in the glass, they will look the same after a year of alcohol soaks as they do out of the box.

What Makes It Worth Buying

It solves a real fitment gap. Female bowls in the wider size are not easy to find, and in our experience the pipes that need them are not rare.

Flat faces, no rolling. The triangular head sits still on a flat surface.

Colour in the glass. Slyme and black are part of the material, not a finish applied over it.

Short body. Two inches means less of it exposed to elbows, sleeves, and table edges.

One clear option. A single configuration, so the only thing we ask you to confirm is that your joint matches.

The Table In Sentences

Written out: a glass flower bowl with a female 18mm joint, 2 inches long, made for dry flower, packed at 6 ounces, and in stock. It is finished in black and slyme green with a triangular head. Joint angle and bowl depth are not recorded in our data, so neither appears above, and we are not going to approximate them for the sake of a fuller table.

Benefits In Short

  • Female joint fits pipes that present a male end
  • Cut at the wider 18mm standard
  • Triangle head resists rolling on a flat surface
  • Two colours worked into the glass, not painted on
  • Two inch length keeps it clear of your hands
  • Solid glass with nothing bonded or fastened on
  • Easy to identify at a glance among plain bowls
  • Simple to clean with a standard soak
  • No screen or extra part needed to use it
  • Works as a daily bowl or a backup in the case

Using It

Seat it gently. A female joint slides down over a male stem, and pushing hard at an angle is how people chip the inside edge. Straight down, light pressure, and stop when it stops.

Pack loose then firm. The load wants air moving through the bottom and something solid on top for the ember to sit in.

Set it down on a face, not a corner. That is what the triangle is for, and it will stay where you put it.

Pro Tip: Take a photo of your pipe's joint before you shop for any bowl, with something familiar next to it for scale. When you are standing in the middle of a page trying to remember whether your piece has a socket or a spike, a picture on your phone settles it in two seconds.

Who It Suits

Owners of male stemmed pipes. You need a female bowl and you have been finding mostly the other kind.

People who set things down mid session. A bowl with flat faces stays put.

Anyone who likes green glass. Slyme against black is a strong combination in daylight.

The careful buyer. You read the joint spec before the photos, which is the right order.

Joint And Colour Questions

What does female mean on a bowl?

A female bowl has the joint on the inside, so a male stem slides up into it. Most flower bowls are the opposite. This one is listed female at 18mm, which means it belongs on a pipe or stem that presents a male end rather than a socket.

How do I check whether I need female or male?

Look at the piece the bowl has to join. If your pipe ends in a socket you drop a bowl into, you need a male bowl and this is not it. If it ends in a tapered spike sticking up, a female bowl like this one is the correct answer.

Is 18mm the size I have?

This bowl is cut at 18mm, the wider of the two common flower joint standards. Compare it against the joint on your pipe before ordering. Getting the gender right and the size wrong lands you in the same place as getting both wrong, so check twice.

What is slyme?

Slyme is a colour name for a green glass that shifts depending on the light behind it. Paired with black here, it gives the triangle body a two tone look. The colour is in the glass rather than applied on top, so cleaning solvent will not strip it.

Why a triangle shape?

The head is worked into a triangular profile instead of a round one, which is where the name comes from. Flat faces give your fingers something to register against, and a bowl that does not roll when you set it down on a table is quietly useful.

How long is the bowl?

Two inches end to end. That keeps it tight against whatever it seats on rather than standing far out from the pipe. Short bowls take fewer knocks and put less strain on the joint, which is the part you really do not want to break.

What is the shipping weight and stock level?

It goes out at 6 ounces packed, and ten were showing available when this page was written. Small glass ships wrapped, so packaging accounts for a good part of that number. The cart carries the live count if you want to be sure before ordering.

Care And Cleaning

Soak it in isopropyl with coarse salt, sealed, and leave it. The colour is in the glass and does not care about solvent, so you can be thorough without worrying about the finish.

The inside of a female joint needs its own attention. Residue builds on that inner wall and makes the fit tighten, so run a swab around it every time you clean rather than only when it starts to bind.

Rinse well and let it drain fully before it goes back on the pipe.

Warning: Do not use boiling water on cold glass. When one part of the wall heats and expands ahead of the part next to it, the stress goes somewhere, and on glass it goes into a crack. A bowl with corners and flat faces has uneven thickness by design, which makes it more sensitive to that, not less. Warm it in stages or clean it cold.
