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. Warm it firstRinse a cold piece in warm water before you pour something boiling into it.
- 2. Cloth betweenStack with a cloth in the gap. Glaze is glass, and glass scratches glass.
- 3. Cloth, not wireWarm water and a cloth take off everything a mug picks up in a week.
When stacking glass or ceramic items for storage, place a cushion of soft material between each piece.

Great size teacup and lovely earthy colors
We bought this teacup with cover for our daughter-in-law for Christmas and she loves it! Perfect size and she loved the earthy color combination!
Great product
Absolutely love these. I bought 4 . I drink tea every day . I use the insert for my tea bag instead of loose tea leaves. So much easier than squeeing the tea bag on a spoon. And I love the steeping lid. The price is just right. The quality is great, dishwasher safe, keeps my tea warm. Although the handle is a bit hot right after microwaving, but cools pretty quickly. Not the prettiest color but I was going for function and price and this hit the spot.
Great coffee cup
Love this cup. It has become my dedicated coffee cut. Grind a tablespoon of beans, dump in strainer, let sit in hot water 5-10 minutes. Dip the strainer up/down 5 or so times then drink.
Perfect mug for brewing loose tea and garden herbs
Great size, love the lid and infuser. Looks good feels good... Overall very happy with the purchase!
Great for the slow drinking tea lover in your life
Got this for my husband who loves loose leaf tea but also has to worry about it getting cold on his desk while he's teaching. This mug means he doesn't have to cover his tea with paper towels to keep it warm anymore! It's also stylish, and feels solid without being heavy. I recommend it for any tea lovers or for anyone who likes to keep their drinks hot in a more standard mug.
Perfect size!!
Have been brewing, long tea, loose leaf, and needed a larger strainer. This is great because it is the size of the cup and you can use the lid to rest and catch the strainer on. It’s about 16 ounces and is a super cute design.

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.
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.
