Bosmarlin Ceramic Tea Cup with Infuser and Lid (Deep Blue)

Reactive glaze is a ceramic finishing technique where the glaze interacts with the kiln's heat in slightly unpredictable ways, creating unique color variations and subtle patterns on each mug. No two mugs look exactly the same, which gives them a handcrafted, artisan quality. Reviewers frequently mention how beautiful and elegant the finish looks — it's one of the most commented-on features. The Deep Blue color in particular gets a lot of compliments.

It's a significant upgrade, according to reviewers. Standard tea balls and spoons are small and cramped — they don't give leaves room to expand, which limits flavor extraction. The Bosmarlin's deep infuser basket gives leaves much more space to unfurl and steep properly, and the fine mesh does a better job of keeping small particles out. Several reviewers specifically mention switching from tea balls to this mug and noticing the difference in their brew quality.

One reviewer did mention that the mesh is fine enough that water drains a bit slowly through the infuser. This is honestly a trade-off — the finer mesh means virtually no tea particles in your cup (which most reviewers love), but it can take a moment longer for the water to flow through. For most people, this isn't noticeable during normal steeping. If you use very finely ground tea, you might notice it more than with standard loose leaf.

13.5 oz is a great middle ground. It's large enough for a satisfying full cup of tea without needing constant refills, but not so oversized that your tea goes cold before you finish it. Reviewers seem happy with the capacity — it works well for morning rituals, all-day sipping at work, or a relaxing evening cup. If you're used to standard 8-10 oz mugs, you'll appreciate the extra volume without the mug feeling bulky.

The ceramic construction naturally retains heat well, and the included lid makes a real difference — it traps steam and heat during steeping and keeps your tea warmer for longer while you sip. Multiple reviewers mention the lid's heat retention as a genuine benefit, especially for people who like to drink their tea slowly over time. It won't keep tea hot for hours like an insulated tumbler, but for a ceramic mug, it performs well.

Multiple reviewers have bought these specifically as gifts, and several went back to buy extras for friends and family after trying their own. The reactive glaze finish gives it a premium, artisan look that photographs well and feels special to unwrap. With five color options, you can pick one that matches the recipient's style. It's practical enough to actually get used daily, which is the mark of a great gift — not just pretty, but genuinely useful.

It's practically designed for it. The 13.5 oz capacity means fewer trips to the kettle, the infuser makes brewing at your desk simple (no extra accessories needed), and being dishwasher safe means low-maintenance cleanup. The lid keeps your tea warm through meetings or focused work sessions. Several reviewers mention using it as their daily work mug, and the fact that people buy multiples suggests it holds up to heavy rotation.

Surprisingly, yes. Several reviewers have found it works well for making drip coffee too — you can put coffee grounds in the infuser and pour hot water over them for a simple single-cup brew. It's not going to replace a proper pour-over setup, but for a quick cup it does the job. The fine mesh keeps grounds out of your drink just like it does with tea leaves.

Very. Reviewers highlight cleanup as one of the mug's strengths. You can toss the ceramic cup right in the dishwasher, and the stainless steel infuser rinses clean easily. One nice detail — the lighter interior glaze makes it easy to see when the mug needs cleaning, so tea stains don't build up unnoticed. For everyday maintenance, a quick rinse after each use is usually all it takes.

Yes — reviewers describe the handle as large and comfortable. It's designed to give you a secure grip even when the mug is full with 13.5 oz of hot tea. This matters more than people think, especially for a mug you're using daily. Nobody wants to fumble a full cup of hot liquid, and the generous handle size helps prevent that.

Reviewers describe the construction as sturdy and durable. The ceramic is solid — it doesn't feel thin or fragile like some decorative mugs. It holds up well to daily use, dishwasher cycles, and microwave heating. Of course, it's still ceramic, so it can break if dropped on a hard floor, but for normal everyday use, it's built to last.

Absolutely — and some reviewers specifically use it for that purpose. The deep infuser gives you enough room to combine different loose leaf teas, dried herbs, or flowers for custom blends. The fine mesh keeps everything contained, and the lid traps the aromas during steeping so you get the full experience. If you like experimenting with your own tea combinations, this mug makes it easy.

The Bosmarlin mug is available in five colors, all featuring that distinctive reactive glaze finish. The Deep Blue is one of the most popular options, but you have four other choices to match your kitchen or personal style. The reactive glaze means each mug has slight natural variations in color and pattern, so every one feels a little unique even within the same color family.

It works for a wide range of tea drinkers. Beginners love the all-in-one simplicity — no separate accessories needed, just add leaves, water, and steep. Enthusiasts appreciate the deep infuser that lets leaves expand properly and the fine mesh that keeps their cup clean. It's great for daily home or office use, custom blending, and makes a thoughtful gift. The only people who might want to look elsewhere are those who need something truly travel-friendly, since this is a standard ceramic mug without insulation or a spill-proof lid.

The Bosmarlin mug is genuinely one of the easiest ways to get into loose leaf tea. Here's the process: drop your loose leaf tea into the deep infuser basket, place it in the mug, pour hot water over the leaves, put the lid on to keep the heat in, and steep for your desired time. When it's done, lift out the infuser and set it on the flipped lid — it doubles as a drip tray. No separate infuser balls, no spoons, no mess. Reviewers specifically praise the all-in-one design as beginner-friendly.

One reviewer noted that the bottom surface is rough or unglazed. This is actually common with ceramic mugs — the base is left unglazed so it sits flat in the kiln during firing. If you're concerned about it scratching delicate surfaces, a coaster or placemat will solve that easily. It doesn't affect the mug's function or the drinking experience at all.

There are many well-known names, but Bosmarlin has carved out a loyal following specifically for their tea infuser mugs. What sets them apart is the combination of aesthetics and function — the reactive glaze finish gives each mug a unique, handcrafted look, while the deep infuser and fine mesh strainer actually perform well for serious tea brewing. They offer five color options in this style, so you can match your kitchen or collect a set.

For a tea mug specifically, you want to look at material safety (ceramic is ideal), capacity (13.5 oz is a solid sweet spot — enough for a full steep without being unwieldy), and practical features. The Bosmarlin checks the important boxes: it's dishwasher and microwave safe, has a comfortable large handle, and the reactive glaze means each mug has a slightly unique finish. If you're a loose leaf drinker, having a built-in infuser like this one saves you from buying separate accessories.

Ceramic is one of the healthiest materials for drinkware — it's non-toxic, doesn't leach chemicals, and won't absorb flavors or odors. The Bosmarlin mug is made from ceramic with a reactive glaze finish, which means it's free from the concerns you'd have with plastic (BPA, microplastics) or even some metals that can react with acidic teas. It's also microwave and dishwasher safe, so you're not dealing with coatings that degrade over time. For daily tea drinking, ceramic is hard to beat.

Tumblers are great for on-the-go, but if you're steeping loose leaf tea at home or at your desk, a dedicated tea mug like the Bosmarlin works better. The built-in infuser gives your tea leaves room to expand properly (which a tumbler's narrow infuser often doesn't), the ceramic keeps your tea warm, and the lid traps heat during steeping. It's really designed for the ritual of making a proper cup of tea, not just carrying a beverage around.

In the tea world, all-in-one steeping mugs with built-in infusers have become incredibly popular because they simplify the whole loose leaf experience. The Bosmarlin mug hits that sweet spot — it combines a ceramic cup, a deep stainless steel infuser, and a lid that doubles as a coaster, all in a beautiful reactive glaze finish. Multiple buyers have liked it enough to purchase extras in different colors, and it's frequently bought as a gift, which says a lot about its appeal.
