About This Product
The reactive glaze produces rich, varied color depths that reviewers consistently single out as a standout quality. At 13.5 oz, the generous capacity pairs with a deep infuser basket that gives loose leaves room to fully expand during steeping. The ultra-fine mesh keeps even small-particle teas residue-free, though the tight weave means draining is noticeably slower than with coarser infuser designs. Both mug and infuser are dishwasher and microwave safe, and the lid doubles as a rest for the spent infuser. Best suited for home or office loose leaf drinkers who want an all-in-one setup without separate equipment.
Is Bosmarlin Ceramic Tea Cup with Infuser and Lid (Brown Grey) Right for You?
How fine is the mesh on the Bosmarlin tea infuser?
The mesh is ultra-fine — fine enough that reviewers describe it as keeping even small tea particles and grounds completely out of the finished cup. Self-described 'tea snobs' have praised the clean brew quality. One thing to be aware of: the mesh is so fine that water can drain a bit slowly, especially with finely cut teas like rooibos or CTC black tea. For standard loose leaf teas with larger leaves, it works beautifully.
Can the lid really be used as a coaster for the infuser?
Yes, and this is one of the most-praised features. When you're done steeping, you flip the lid over and rest the wet infuser on it — it catches all the drips so you don't end up with a puddle on your desk. Four different reviewers specifically called out this dual-purpose lid as a thoughtful design detail. It's a small thing, but it makes the whole brewing routine cleaner and more convenient.
Does the Bosmarlin infuser mug actually keep tea warm?
Yes — reviewers specifically mention that this mug keeps tea warm longer than expected. The ceramic walls provide natural insulation, and the fitted lid helps trap heat during steeping and while you're sipping. It won't keep tea hot for hours like a double-walled vacuum tumbler, but for a sit-down tea session at home or the office, it performs well.
Is the Bosmarlin tea mug good for beginners?
It's actually one of the best entry points into loose leaf tea. You don't need a teapot, a separate strainer, or any other equipment — everything is built into one mug. The infuser fits securely, the lid keeps heat in during steeping, and cleanup is as easy as tossing everything in the dishwasher. Reviewers describe it as a forgiving, simple-to-use system that's perfect for learning loose leaf preparation without any learning curve.
Does the Bosmarlin mug have any downsides?
Two things to know: the bottom of the mug is unglazed (rough), so you may want to use a coaster to avoid scratching delicate surfaces. And the infuser mesh is extremely fine, which is great for clean tea but can mean water drains through slowly — especially with finely cut teas. If you primarily drink full-leaf teas, the slow draining likely won't bother you. If you brew a lot of rooibos or finely cut herbal blends, you might notice it takes a bit longer.
Is the Bosmarlin tea mug dishwasher safe?
Yes, both the ceramic mug and the stainless steel infuser are dishwasher safe, which reviewers have confirmed through regular use. It's also microwave safe, so you can reheat your tea if it cools down. This combination of convenience features makes it a practical everyday mug rather than something you need to baby.

Will tea enthusiasts appreciate the Bosmarlin infuser mug?
Surprisingly, yes. While it looks like a beginner-friendly product, several self-described tea enthusiasts and 'tea snobs' have praised it. The infuser is deep enough to allow proper leaf expansion, which is critical for getting full flavor extraction. The ultra-fine mesh produces a very clean cup without residue. It's also a good mug for experimenting with custom blends. That said, if you prefer gongfu-style brewing or want precise temperature control, this is more of a casual daily driver than a ceremonial piece.
What types of tea work best in the Bosmarlin infuser mug?
Full-leaf teas work best — think whole leaf green tea, oolong, white tea, and large-leaf black teas. The deep infuser gives leaves plenty of room to unfurl and release their full flavor. Herbal teas with larger pieces (chamomile flowers, mint leaves, dried fruit chunks) also work great. Finely cut teas like CTC black tea or powdered rooibos will brew fine but may drain more slowly through the ultra-fine mesh. For matcha or very powdery teas, you'd want a different tool altogether.
Can I steep tea multiple times in the Bosmarlin mug?
Absolutely. The deep infuser design is actually well-suited for multiple steeps. Just lift out the infuser, rest it on the lid, enjoy your first cup, then place the infuser back in with fresh hot water. Many quality loose leaf teas — especially oolongs, green teas, and white teas — taste even better on the second or third steep. The large infuser gives leaves enough room to re-expand each time.
Is 13.5 oz a good size for a tea mug?
13.5 oz is a solid sweet spot for tea. It's large enough for a satisfying serving without your tea going cold before you finish it, and multiple reviewers confirm the capacity is good for daily use. For reference, a standard coffee mug is about 12 oz, so this gives you slightly more room. If you prefer very large mugs (16+ oz), this might feel a little small, but for most tea drinkers it's just right — especially since loose leaf teas are often meant to be enjoyed in moderate portions and re-steeped.
How sturdy is the Bosmarlin ceramic tea mug?
Five reviewers specifically describe it as sturdy and well-made. The ceramic feels substantial — it's not a thin, fragile piece. Of course, it's still ceramic, so it can break if dropped on a hard floor, but for everyday use it holds up well. The infuser and lid also fit securely, so you're not dealing with pieces that slide around or fall out.
Is the handle comfortable on the Bosmarlin tea cup?
Yes — three reviewers specifically mention the large, comfortable handle. This matters more than you'd think with a ceramic mug full of hot tea. The handle is big enough to get a secure grip without your fingers touching the hot ceramic, which makes it comfortable for longer sipping sessions.

What does the reactive glaze look like on the Bosmarlin mug?
Reactive glaze creates unique color variations on each mug — no two are exactly alike. Reviewers frequently praise the beautiful appearance, with eight different reviewers specifically mentioning how good it looks. The Brown Grey color has an earthy, handcrafted aesthetic. There are five color options total, so you can pick one that fits your kitchen or office style. The glaze gives it more of an artisan pottery feel than a mass-produced mug.
Does the Bosmarlin mug make a good gift for tea lovers?
It's frequently bought as a gift, and reviewers consistently mention it works well in that role. The reactive glaze makes it look more expensive than it is, the five color options let you pick something personal, and the all-in-one design means you're giving someone everything they need to start (or continue) brewing loose leaf tea. It's the kind of thoughtful, practical gift that actually gets used daily rather than sitting in a cupboard.
Can I use the Bosmarlin mug for coffee or just tea?
While it's designed as a tea infuser mug, the ceramic mug itself works perfectly well for coffee, hot chocolate, or any other hot beverage — just remove the infuser. Some people even use the fine mesh infuser for single-cup French press-style coffee, though that's not its primary purpose. The 13.5 oz capacity and comfortable handle make it a solid everyday mug regardless of what you're drinking.
Does the unglazed bottom scratch tables?
One reviewer noted the bottom is rough and unglazed. It could potentially mark up soft wood surfaces or glass tabletops. A simple fix is to use a coaster or stick a felt pad on the bottom. This is actually common with handmade-style ceramic mugs — the unglazed foot ring is how reactive glaze pieces are fired in the kiln to prevent them from sticking.
How to use drinkware for beginners?
If you're new to loose leaf tea, the Bosmarlin mug makes it about as simple as it gets. Drop the stainless steel infuser into the mug, add your loose leaf tea (about 1-2 teaspoons), pour hot water over the leaves, and put the lid on to keep the heat in while steeping. When your tea is ready, lift the infuser out and rest it on the flipped-over lid — it doubles as a drip tray. That's it. No teapot, no separate strainer, no mess. Reviewers specifically mention this is a great all-in-one system for beginners learning loose leaf tea.
What is the point of a tumbler cup?
Tumblers are designed for portability and insulation, but they're not always ideal for brewing loose leaf tea. If you're primarily drinking tea at home or at your desk, a ceramic infuser mug like the Bosmarlin offers a better experience — you get proper heat retention from the ceramic, a full-size infuser that lets leaves expand fully, and a lid to keep your tea warm. The open-top design also lets you enjoy the aroma, which is a big part of the tea-drinking experience that sealed tumblers miss.

Is ceramic better than glass for a tea infuser mug?
Both are excellent, non-reactive choices, but they have different strengths. Ceramic like the Bosmarlin mug retains heat better, which keeps your tea warm longer and is more forgiving during steeping. Glass lets you watch the leaves unfurl, which some tea lovers enjoy. Ceramic is also generally more durable for daily use — you won't worry as much about thermal shock or dropping it. If warmth and everyday durability are your priorities, ceramic is the way to go.
What kind of cup is best for tea?
For loose leaf tea, a ceramic mug with a built-in infuser is hard to beat — it's an all-in-one solution that eliminates the need for separate teapots or strainers. The Bosmarlin tea cup checks those boxes with its ceramic construction, stainless steel infuser, and fitted lid. Ceramic is ideal because it retains heat well, doesn't impart any flavors to your tea, and is naturally food-safe. Reviewers note this mug keeps tea warm longer than expected, which is exactly what you want from a good tea cup.
What to look for when buying drinking glasses?
For a tea mug specifically, you want to consider material (ceramic is excellent for heat retention and safety), capacity (13.5 oz is a solid sweet spot — enough tea without going cold before you finish), ease of cleaning (dishwasher safe is a huge plus), and how comfortable it is to hold daily. The Bosmarlin mug scores well on all of these — reviewers frequently praise its large, comfortable handle and sturdy construction. If you brew loose leaf, the quality of the infuser matters too, and this one has ultra-fine mesh that keeps even rooibos particles out of your cup.
What is the best material for tea cups?
Ceramic is widely considered the best material for tea cups. It's non-reactive, meaning it won't leach chemicals or alter the flavor of your tea the way some plastics or metals can. It also retains heat beautifully, keeping your tea warm throughout a long steeping session. The Bosmarlin mug uses a reactive glaze over ceramic, which gives each cup a unique, handcrafted look while maintaining all the practical benefits of ceramic — including being microwave and dishwasher safe.
Which mugs are best for tea?
The best tea mugs combine a few key features: good heat retention, a quality infuser for loose leaf brewing, and comfortable daily use. The Bosmarlin ceramic tea mug hits these marks well — it's 13.5 oz (a generous single serving), has a fine mesh infuser that keeps even small tea particles out of your cup, and a lid that doubles as a resting spot for the wet infuser. Multiple reviewers describe it as sturdy and well-made, and it's both dishwasher and microwave safe, which makes it practical for everyday use.
