What the glaze does

We mix this glaze to sit still in the heat, so the finish stays even across the piece and from one piece to the next.

Care
  1. 1. Warm it firstRinse a cold piece in warm water before you pour something boiling into it.
  2. 2. Cloth betweenStack with a cloth in the gap. Glaze is glass, and glass scratches glass.
  3. 3. Cloth, not wireWarm water and a cloth take off everything a mug picks up in a week.

Nice size and shape, but not nearly as bright as the photo

This is a good, sturdy mug and has a pleasing shape and a great size for making lattes at home or making a big cup of tea. However, it loses one star for not being as bright as the picture. I have been wanting a nice, bright sunshine yellow to help cheer me in the morning which was my main purpose for choosing this particular mug, but this is a bit more of a dull not quite mustard yellow. It's still a very nice color but it doesn't quite have the same mood lifting effect for me. I still like the shape however so I will still be using it, I just need to go on the hunt for a brighter color now.

I highly recommend this beautiful mug!

Beautiful mug! Well made and easy to hold. I love the size as it is large enough for me to be able to add my cream and still have a generous cup of coffee. It works well with my desktop coffee warmer too. I love the color and the glaze is lovely as well. I'm very happy with it!

Nice substantial mug ...

I purchased two of the "royal blue" color -- it's actually closer to navy blue, which is actually what I wanted -- to go with some new dishes that have a "Spanish tile" pattern in navy, royal, soft orange, and yellow. Perfect match! So the color works great.Quality: very good! No nicks, no glaze issues, no flaws of any kind that I can see. This is a nice large mug -- 18 oz -- and sometimes these larger mugs can carry a little more weight than I like (I have arthritis in my hands and shoulders). But the design of this one makes it nicely balanced -- the handle is at exactly the perfect angle to provide a secure grip without strain. Wasn't expect that, so it's a definite plus.I like this design and quality enough to purchase an additional two of these in the yellow color. Another review showed that it's a softer yellow than the product photo and that's closer to the yellow in my new dishes. So I have no qualms at all about ordering.Nice mug, great size, excellent quality. High recommended.

Awesome Mug – Durable, Functional, Aesthetic and Worth It!

I really love the Bosmarlin coffee mug — it’s the perfect mix of style and everyday function. It holds a good amount (an 11 oz La Colombe can with ice fits easily), and the thick ceramic keeps drinks warm and makes the mug feel super sturdy. It’s microwave safe and has held up great over time.The handle is super comfortable — you can fit 4 fingers through it with no problem. It’s also really easy to clean, and I’ve never had coffee or tea stains stick around. For the quality and how well it performs, I would say it’s a great deal. Whether you use it every day or just now and then, this mug’s a solid pick. Highly recommend!

Rise and Shine with Glossy Mugs!

Love these mugs. Perfect size, heft, color. A little glossy to grip from the top but you’re not going to do that with a hot cuppa in any event. I got four colors, and plan to get more. Highly recommend, just save a few more for me!

Pretty in pink

I love them. In fact I’m drinking my morning coffee from one right now. The size and shape are perfect and the handle is comfortable. The soft pink color is so pretty. I’m very particular about the feel of my coffee mug. This one feels just right.

More Bosmarlin everyday mugs

All 49 Everyday Mugs

What you are holding

The same eight things are true of every piece we make.

Fired hard

Stoneware fires dense, so it holds heat and shrugs off the knock against a tap.

Glaze that moves

Mineral oxides travel in the heat, so the firing draws the line between colours.

Handles for full mugs

A large mug carries a handle you can put a whole hand through.

Made to stack

Wide feet and even rims, so a shelf of them sits flat.

A Bosmarlin mug in a reactive glaze

Dishwasher and microwave

Stated on nearly every piece in the range, and true of the glaze rather than a hope.

No two alike

Speckles land differently and a fade can sit higher or lower on the next piece.

Lead-free and cadmium-free

As stated on the range. The care page spells out what that means.

Sized for real drinks

From 8.5 oz for a cappuccino to 50 oz for a mug of soup.

Stoneware, porcelain and earthenware

Three words used loosely on the same shelf. They describe how hot the clay was fired and how much water it will still absorb, and that difference decides how a piece behaves in a dishwasher, in a microwave and against the edge of a sink.

Stoneware, what we make

  • Fired hot and dense, so it absorbs almost no water
  • Heavy in the hand and stable on a desk
  • Chips are rare, and a chip does not soak up coffee
  • Holds heat noticeably longer than a thin cup

Porcelain

  • Fired hot too, but thrown thin and light
  • Elegant, and far easier to chip on a tap
  • Cools faster because there is less body to hold heat
  • Usually sold as a full service rather than by the piece

Earthenware

  • Fired lower, so the body stays porous
  • Depends entirely on its glaze to hold liquid
  • A crazed or chipped glaze lets the body absorb
  • Lighter and cheaper, and shorter lived in daily use

The three words describe firing temperature and how much water the fired body still takes up. Everything else follows from that.
