The Fireprint Mug (16 oz)

No two alike.
The fire decides.

A real ceramic mug with a reactive glaze that melts and flows in the kiln — so the pattern on yours happened once, and never again. Coffee that tastes like coffee, with a lid and sleeve for the days you're on the move.

Our story

There are only three cups like it in the world.

In Japan, three tea bowls are so rare they are National Treasures. They were fired in China's Jian kilns about 800 years ago, and their glaze shimmers like a night sky. Potters have tried to make another one on purpose for centuries. The fire has never agreed.

The Japanese have a word for what made them: yōhen. It means "kiln change," the moment the fire takes over from the maker.

Fireprint is inspired by that idea. Every one of our mugs goes into the kiln looking the same and comes out different. The glaze melts, pools and flows in the heat, so the colors that settle on yours will never happen again. Like a fingerprint, left by fire.

Same color, different fire

Same glaze. Same kiln. A completely different cup.

These two mugs got the exact same glaze and went into the same kiln. Look at how differently they came out.

At full heat, the glaze pools, drips and flows in its own direction. When it cools, it holds a pattern that happened once and will never happen again.

You pick the color. The fire picks the pattern.

Dehua, China

Glazed by hand in a town built on fire.

Every Fireprint is made in Dehua, in China's Fujian province, a town that has been firing ceramics for centuries. Its historic kiln sites are part of a UNESCO World Heritage listing.

Each mug passes through nine steps and at least nine pairs of hands. It is dipped into its glaze by hand, then fired at 2,370°F for over ten hours. When the kiln opens, no one knows exactly what they'll find.

Made for your quiet first cup, and for the days you take it with you.

Coffee that tastes like coffee

Real ceramic, inside and out. You get the flavor of your coffee, with no metallic tang from steel and no plastic taste from a throwaway lid.

Color all the way in

The glaze keeps going on the inside. Look down into your cup and the pattern is still there.

Ready when you are

A soft silicone sip lid keeps spills down on the walk to the car. A ribbed sleeve keeps your hands comfortable.

Nobody else has yours

Ten colors, and endless variation inside each one. The mug that arrives at your door is the only one like it.

A gift that's never the same twice

Two mugs. Never the same.
Just like you two.

One for you and one for her. Your daughter, your mom, your best friend. Pick your colors side by side, then watch how the fire made each one its own.

Pretty but not for everyone

The organic glaze is beautiful to me, though people who like perfectly even finishes may prefer a different style.

M
Madison Bell
Stylish and practical enough

I like the larger capacity and ceramic feel. It is better suited to sipping at a desk than rushing through a commute.

K
Kimberly Reed
Nice design, limited portability

I like the sleeve and lid for moving around the house. I would still carry it upright to avoid spills.

E
Emily Wilson
Great concept

The kiln-made variation is interesting. I only wish I could choose the exact pattern before ordering.

O
Olivia Carter
A little extra maintenance

It is a gorgeous cup, but hand washing the mug and lid takes a bit more effort than my usual dishwasher routine.

B
Brianna Baker
Beautiful everyday mug

The size is generous and the finish looks special. Just remember it is a mug, not a fully insulated bottle.

S
Stephanie Torres
Good for the desk

The lid helps with little splashes, but it is not sealed. I would use it at home or at work rather than in a bag.

A
Alexis Miller
Ceramic has its tradeoffs

I prefer the feel of ceramic to metal, but it is naturally more fragile. I would handle this one carefully.

M
Molly Stewart
A unique gift option

The colors are lovely, but the unpredictable pattern might not suit someone who wants an exact match to a photo.

H
Heather Wright
Nice but needs care

The glaze is the star of the show. Hand washing is manageable, although I usually prefer dishwasher-safe mugs.

D
Danielle Cox
Pattern will vary

I like the unique finish, but anyone expecting the exact swirls in the product photos should know each mug will look different.

A
Amy Allen
A bit tall for my shelf

The design is lovely. I would just double-check the height if you have shorter cabinet shelves.

J
Jennifer Evans
Beautiful with one drawback

I wish it were microwave safe for reheating coffee. Other than that, the ceramic design is very appealing.

M
Michelle Phillips
Gorgeous but not insulated

It looks fantastic, but it will not keep coffee hot for hours like a vacuum tumbler. That tradeoff is worth considering.

K
Katherine Lewis
Not a travel tumbler

The sip lid is useful for short walks, but I would not put this in a backpack. It is more of a desk mug.

L
Lily Thompson
Beautiful for gifting

Picking two different glaze colors would make a really sweet matching-but-not-matching gift.

S
Sophia Perez
Really nice proportions

The taller shape looks elegant and still offers enough room for a generous coffee.

E
Emma Bailey
Pretty, but hand wash only

I love the glaze, though I wish it could go in the dishwasher. It is one more thing to wash by hand.

A
Anna Morgan
A mug with personality

I am drawn to everyday objects that feel a little different, and this definitely fits that category.

J
Jenna Nelson
A great shelf piece

Even when it is empty, it looks decorative. The colors are the main attraction for me.

T
Taylor Collins
Lovely gift for my mom

The one-of-a-kind finish makes it feel much more thoughtful than a generic mug.

L
Leah Green
Coffee tastes right in ceramic

I like the clean feel of ceramic for hot drinks. This has the appeal of a traditional mug with a little extra convenience.

A
Audrey Rogers
Love the earthy look

The glaze has a natural, almost landscape-like quality to it. It would fit beautifully in a warm kitchen.

H
Hailey Davis
Such a fun concept

Letting the kiln determine the final pattern is a really interesting idea. I love the unpredictability.

P
Paige Gray
The sleeve is a nice touch

The ribbed sleeve adds some grip while keeping the beautiful ceramic visible.

M
Morgan King
Feels more personal

I really like the idea of owning a ceramic piece with a pattern that cannot be reproduced exactly.

C
Claire Ward
Great for my home office

The size and sip lid suit long mornings at my desk. The look is a bonus.

A
Abigail Parker
A beautiful color palette

There are enough glaze options to match different tastes, but each still feels distinctive.

M
Melissa Hall
A special little detail

The glazed interior is what sold me on the design. It makes the whole piece feel considered.

E
Erin Richardson
Lovely for tea too

I picture this being just as nice for a big cup of tea as for coffee. The shape feels versatile.

C
Caroline Clark
Really striking design

The contrast between the darker and lighter glaze areas is beautiful. I like that no two sides are exactly alike.

J
Julia Turner
Worth displaying

I would happily leave this out on an open shelf instead of hiding it in the cupboard.

R
Rebecca Murphy
Perfect for a coffee lover

The combination of ceramic and unusual color patterns makes this a fun option for someone who already owns plenty of mugs.

E
Elizabeth Mitchell
The texture looks amazing

The flowing glaze gives the mug an organic look. It has a lot more personality than a plain solid-color cup.

Questions

Will my mug look like the photos?

It will be the color you choose, but the exact pattern is decided in the kiln. The pools, drips and speckles on yours will be unique. That's the whole point of Fireprint.

Is the lid leak-proof?

It's a spill-resistant sip lid, like the one on a coffee shop cup. It's great for the walk to the car or your desk, but it isn't made to be tossed in a bag on its side.

Is it dishwasher and microwave safe?

Hand wash with warm, soapy water to protect the glaze. Not for the microwave or dishwasher.

How long does shipping take?

Kiln fired and packed with care. Arrives in 7 to 10 business days, always with free shipping.

What if it arrives broken?

Send us a photo and we'll send you a new one, free. Ceramic travels a long way, and we've got you covered.

Somewhere in the kiln, yours is already waiting.

One of a kind, from the first pour to the last sip.
