Start with how you actually smoke
Most people shopping for glass online pick by photo. I understand the pull of a fumed spoon with swirls in it. But the pipe that ends up in your hand every night is chosen by three boring things: how much you load at once, how big your hands are, and where you smoke.

A one-hitter suits a quick hit on a walk. A spoon suits a couch session with a friend. A chillum suits someone who wants a straight, small-bore draw and no carb to fumble with. Decide that first, then go shopping.

Match the pipe to the session
Spoons usually run 2 to 4 inches. Under 3 inches is pocket-friendly but the bowl is tiny, so you reload often. Over 4 inches gives you a cooler hit and more room for your fingers, but it will not disappear into a jacket pocket.

If you cough easily, length helps more than anything else. Distance between the bowl and your mouth lets the smoke shed heat before it reaches you.
Think about the carb
The carb is the small hole you cover with a thumb. Left side suits right-handed users, right side suits lefties. Some pipes have the carb pushed close to the bowl, which makes it awkward to reach without burning a knuckle. On a photo, look for a clear gap between bowl and carb.
Parameters worth checking before checkout
- Glass thickness. Ask for wall thickness or at least a weight in grams. A 3-inch spoon in the 30 to 50 gram range feels solid. Anything described only as "thick" with no number is a guess.
- Bowl capacity. Listings that give a bowl diameter in millimeters save you a bad purchase. 14 mm to 18 mm is a normal spoon bowl.
- Joint and stem fit. For water pipes, the joint size has to match your downstem. 10 mm, 14 mm, and 18 mm are not interchangeable.
- Welds and seals. On a Sherlock or a bubbler, look for smooth bridges with no trapped bubbles or hairlines at the connection points.
- Color versus clear. Clear glass lets you see resin buildup and clean it properly. Fumed and colored glass hides grime, which is fine if you keep a cleaning schedule.
- Kiln-annealed or not. Annealing relieves stress in the glass. Imported pieces often skip it, which shows up as cracks after a month of temperature swings.
Pitfalls that cost money
- One studio photo, no scale reference. A pipe can look 6 inches tall against a black backdrop and arrive at 3 inches. Ask for a shot next to a coin or a ruler.
- "Handmade" with no artist or shop name. Not a dealbreaker, but know whether you are paying for studio glass or factory glass.
- Weak packing. Glass ships fine when it is boxed with foam and double-walled. If the shop will not describe its packaging, expect a broken box.
- Return policies that exclude glass. Many stores void returns once the seal is broken, so damage claims have to be filed within a day or two of delivery. Open the box on camera.
- Age and legality checks. You need to be 21 or older in the US, and shipping rules vary by state. Reputable shops verify at checkout.
- Pricing that is too good. A ten dollar "hand-blown" Sherlock is almost always thin import glass with a rough mouthpiece.
Care matters more than the brand
Resin holds the taste of every past session, so rinse with isopropyl alcohol and coarse salt every week or two. Warm water first, then alcohol, then a thorough rinse. Skip the microwave and skip boiling, since sudden heat changes crack glass faster than a drop does. A clean pipe tastes like the flower you packed, which is the whole point.
Checklist before you hit pay
