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.

Would have been better if the infuser had actually been included.

Extremely disappointed!! The mug was delivered with no infuser whatsoever, which was the main reason I ordered it. The mug itself is pretty, and I'm sure the lid would work great as an infuser coaster after steeping, but I wouldn't know since I didn't get one. I won't be reordering since I dont want to risk spending more money on another mug with no infusers to show for it.

Pretty

Nice mug. Easy to clean since I handwash my dishes. Easy to handle. Pretty design but not quite like the pictures. I wanted the picture version. It almost looks manufactured not homemade. The lid it a nice touch. I use the lid for when I'm outside sitting on the porch and relaxing inside, the lid is a coaster. I have yet to put it in the microwave.

Very nice cup; strong and a good size. Love it.

Beautiful cup and cover keeps tea hot. Love the insert for brewing loose tea; cover fits well over it. Love it and may get another one in another color.

Fantastic infuser!

I love my nightly herbal tea's and this cup with lid allows me to make infusions to get the most benefit from the herbs. Will definitely buy again as the quality is great and delivers the perfect cup of herbal tea.

AMAZING CUSTOMER SERVICE

I ordered this cup for my desk at work. Its perfect bc the strainer means I can use any of the teas I have. When the cup got here the strainer was missing but there was a card with it that had an email for support. I sent them an email and they immediately sent me a replacement. They asked that I reach back out once I received the replacement to be sure it had everything and that it arrived safely. No 21 questions, no fuss. Just quick and helpful!! I will be checking with this company in the future for any other needed items!!P.s. the cup is adorable, the handle is the perfect size and the strainer is fine enough for my finely ground herbal mate tea! You won't be disappointed

Nice.

Nice quality mug with a nice, very fine, infuser basket. No dregs left in the bottom of the cup. Roomy handle for a good grip. The lid is nice for keeping the tea hot and you can rest the infuser on it when you're done steeping your tea. I like to brew a double size cup, I would size up to 16oz next time to leave more room for milk. This mug ( not the infuser basket ) does great in the dishwasher, no problems.

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.
