18mm vs 19mm: They're the Same Joint
Short answer: yes. An 18mm bowl and a 19mm bowl fit the exact same joint. If your bong takes one, it takes the other. Why are there two numbers for one size? Because brands round differently. The joint itself measures about 18.8mm across. Some makers round that down and call it 18mm. Others round it up and call it 19mm. Same piece of glass, same ground-glass taper, same fit — just a different number on the label. This goes back to how glass joints are standardized. In lab gla

Herb Grinder Buying Guide: Teeth, Size & Materials
A grinder looks simple until you start comparing them. Teeth, size, material, number of pieces — here's what each one actually means for how it grinds. Teeth The teeth do the work, so look at them first. Diamond-shaped teeth are the standard for a reason — they shred evenly instead of mashing. More teeth means a finer, more even grind; fewer, chunkier teeth leave a coarser grind. If your grinder turns out dust one week and chunks the next, the teeth are usually why. Size Grin

Oil Banger vs Quartz Banger: Are They the Same Thing?
Short answer: in most shops today, an oil banger and a quartz banger are the same thing — the quartz cup you heat up to take a dab. The different names are about what goes in it, not what it's made of. Where the words came from Oil banger is the older, looser term. People called the attachment an "oil banger" because it was for oils and concentrates, back when the hardware itself was still changing — titanium nails, glass nails, then quartz. The name stuck around in search an

Find your joint size The bowl slides into the downstem (or straight into the piece), and the two sizes you'll run into are 14mm and 19mm. If you still have the old bowl, match it. If you don't, look at the downstem it sat in: a 14mm downstem joint takes a 14mm bowl, and a 19mm joint takes a 19mm bowl. Same rule as downstems — t

How to Measure a Downstem (Length, Joint Size & Gender)
Nothing's more annoying than waiting on a new downstem and finding out it doesn't fit. Here's the three-minute measuring guide so you order right the first time. 1. Length Pull your old downstem out and measure from the top of the ground joint to the very end of the stem. That number is your length. Downstems come in half-inch increments, so round to the nearest one. The stem should reach down near the bottom of your water chamber without touching it — too long and it won't s

Quartz Banger vs Quartz Nail vs Quartz Bucket: What's the Difference?
Short answer: in most shops today, banger, nail, and bucket all mean the same thing — the quartz cup you heat up to take a dab. The different names are history, not hardware. Where the words came from Nail is the oldest term. Early dab rigs used actual titanium nails — a flat nail head you'd heat with a torch. When quartz took over, the name stuck around. Banger describes the bucket-shaped quartz attachment most rigs use now. The cup (the "bucket") holds your concentrate, and
