Water pipes & bongs
by Empire Glassworks
The Red Mushroom Bowl is a handcrafted borosilicate glass bowl piece shaped like a cartoon toadstool — bright red cap, white spots, the full Super Mario aesthetic. Made by Empire Glassworks using intricate lampwork techniques, this 14.5mm male joint bowl fits most standard water pipes and glows in the dark when you kill the lights. At just 35 grams and 6.35cm tall, it's a compact, collectible piece that turns your bong setup into something worth showing off.

Complete your setup: pair the Red Mushroom Bowl with a 14.5mm downstem water pipe for a proper fit. If you want to keep your glass looking fresh, grab a set of pipe cleaners and some isopropyl cleaning solution — lampwork pieces like this one collect residue in the sculpted details faster than plain bowls.
Most replacement bowls are functional but forgettable — clear glass, standard funnel shape, nothing to write home about. The Red Mushroom Bowl is the opposite. Empire Glassworks builds each one by hand using lampwork, which means a glassblower actually sculpts the mushroom shape around the bowl while the glass is molten. You can feel the raised white spots on the cap and the textured stem when you hold it. It's got a satisfying weight to it — 35 grams is light enough that it won't stress your downstem, but heavy enough to feel solid between your fingers rather than flimsy.
The glow-in-the-dark feature is genuinely fun. Leave it under a lamp for a few minutes and it charges up — then hit the lights and the whole body gives off that greenish phosphorescent glow. It's not blinding, but it's bright enough to find your bowl on a dark table without fumbling. Practical and a bit silly, which is exactly the point.
One honest heads-up: this is a single-hole bowl. That means finely ground material can pull through more easily than it would with a multi-hole or screen-fitted design. If that bothers you, drop a small glass screen in before packing. Problem solved for about 50 cents.
If you're weighing this against a standard 14.5mm glass bowl, the difference is purely aesthetic — functionally they do the same job. The Empire Glassworks piece costs more, but you're paying for the handmade lampwork and the collectible factor. Compared to other novelty bowls on the market, Empire Glassworks has a reputation for using proper borosilicate glass (the same stuff lab equipment is made from — thermal shock resistant, harder to crack). Cheaper novelty bowls from no-name brands often use soft glass that chips at the joint after a few weeks. We've seen it happen more times than we can count.

| Glow-in-the-Dark | Yes | No |
| Weight | 35g | 15–25g |
| Hole Design | Single hole | Varies (single, multi, built-in screen) |
| Collectible Value | High — limited edition | None |
We've carried Empire Glassworks pieces for years, and the lampwork quality is consistently a step above the generic novelty bowls that flood the market. The paint doesn't flake, the joints are ground to proper tolerances, and the glass itself can take the thermal cycling of daily use without developing stress fractures. That said — and this goes for any art glass — don't drop it on tiles. Borosilicate is tougher than soda-lime glass, but a 6.35cm mushroom hitting a hard floor is still going to have a bad day. Treat it like the small collectible it is and it'll last you years.
One thing we get asked: does the glow-in-the-dark coating affect the taste? No. The phosphorescent material is embedded in the glass body itself during the lampwork process, not painted on the surface. Nothing touches your smoke that wouldn't touch it in a plain glass bowl.
It fits any water pipe with a 14.5mm female joint, which is the most common size for small to mid-sized pieces. If your bong uses an 18.8mm joint, you'll need a glass-on-glass reducer adapter to make it work.
After 5–10 minutes under a bright light, the glow typically lasts 15–30 minutes before fading. Sunlight charges it faster and brighter than artificial light. It recharges every time you expose it to light again — it doesn't wear out.
Reasonably easy, but the sculpted mushroom shape has more nooks than a plain funnel bowl. Soak it in isopropyl alcohol with coarse salt for 20–30 minutes, then shake gently and rinse. A pipe cleaner helps get into the stem section.
It can, especially with finely ground material. A small glass screen placed over the hole solves this completely. They cost almost nothing and we carry them separately.
Yes. Empire Glassworks uses borosilicate — the same type of glass used in laboratory equipment. It handles thermal shock far better than standard soda-lime glass and is more resistant to cracking from repeated heating and cooling cycles.
Not directly. The Red Mushroom Bowl has a 14.5mm male joint. You'd need a 18.8mm-to-14.5mm glass adapter, which slides into your larger joint and creates the right fit. They're a common accessory.
