20oz Cubes Mug

Sale price$110.00

Glaze and firing variation mean every piece is unique. You will not get the exact item pictured in the listing. We will get as close as our process allows. 

  • Holds: 20 fluid ounces (600 ml)
  • Height: 4.5 inches (12 cm)
  • Width: 4 inches (10 cm)
  • Material: High-fired Porcelain
  • Microwave: Yes
  • Dishwasher: Yes

The geometric surface of interlocking raised cubes creates deep shadow and dimension, giving the glaze paths to flow. Color pools in the recesses and breaks across the edges during the final firing, making every piece one-of-a-kind.

Every Hammerly Ceramics piece is made by Curt and his team in his home studio near Denver, Colorado. Each design begins in 3D modeling software, is printed as a physical prototype, and used to create a custom plaster mold system. The HC logo is cast into the bottom of every mug alongside the year in which it was crafted. The cast pieces are then hand-cleaned, fired, glazed, and fired a final time in a computer-controlled gas kiln where the glazes come alive.

The result is high-fired, glazed porcelain: strong, non-porous, and built to last.

Gorgeous piece! I have thrown for decades and have so much respect for the quality of the piece

Gorgeous piece! I have thrown for decades and have so much respect for the quality of the piece. I purchased for the hubby's 50th Birthday. He loves the rich tones of the blues and the dragon scale appearance. I appreciate the work that went into it! Will save up to buy myself a matching purple mug💜

Simply stunning. Not heavy at all considering its substantial feel as clearly a well made piece of art. I look forward to using this for many years to come. Thank you!

Amazing Mug, Unreal Colors.

Amazing Mug, Amazing Colors.
I have followed Hammerly for 6 months with this mug in my cart. Finally decided to just buy it since I've been obsessed for so long. Exceeded my expectations! My only caveat is that once I had this in hand, I didn't want to drink out of my other mugs anymore. The cubes texture feels amazing in your hand, and the mug is surprisingly sturdy. All around excellence.

bought as a present for my sister

bought as a present for my sister. she loves it too much and is making it precious. :p I’m going to have to figure out how to get her more comfortable with it. My biggest selling point (beyond what you can already see on the site — gorgeous work) is how the pieces feel in hand. All the pieces I’ve purchased— this one too — is fun or ¿comforting? to touch and hold. When you get your hands on one you’ll see what I mean.

These are two of my biggest struggles with selling my work! 1) Buying online means that I am asking people to imagine how the texture feels without being able to experience it and 2) convincing people that these mugs are durable and meant to be used just like any other mug. Thank you for your enthusiasm on these points!

I bought a set of 20-oz coffee cups back in the 80's

I bought a set of 20-oz coffee cups back in the 80's, and over time, they have not survived my many moves. Call me very weird, but I am obsessed with having a nice, interesting cup for my morning coffee, and this one finally made me totally forget about the 80's. It's just right in every way.

I hope your new mug is with you for decades to come!

I ordered this as a gift for my husband and he absolutely loved it! The dragons blood color is amazing

Knowing how hard it can be to shop for gifts for men, it is great to hear giving one of our mugs worked out so well!

Fabulous work

Fabulous work. I have large hands and have been looking for something that fits, but also holds a reasonable amount of coffee. Not only does it meet those requirements, but it is just absolutely beautiful to look at. I have not used another coffee mug since this arrived in the mail!

Hi Herman,

So happy to hear the mug was just the right size for you and I love to hear when one of my designs becomes someone's go-to mug!

Love drinking from it

Beautiful piece of art. Ordered this and a smaller one for my work. Using it every day, and I enjoy drinking my tea from it. So comfortable to hold and beautiful to look at. Love the color and the special design

Greg gets a little nervous every time he packs up a group of mugs to ship out (despite our solid track record shipping ceramics). Glad another collection of mugs got to its destination safe and sound.

Thank you for your support and enthusiasm!

This mug is beautiful, the handle and texture make it wonderful to hold, and its the perfect size for adding as much or as little creamer as I want. I am in love with the colors and how it looks like a bunch of hearts are surrounding the mug!!! Definitely my favorite mug now!!

Awesome craftsmanship. This Mug showed me the difference between run-of-the-mill ceramic products & quality artisanal hand-crafted hand-glazed ceramics. The actual item turned out to be better than the pictures in the end. My only complaint is that Kurt should upload more regularly on his YT channel. I would love to see more crafting, glazing, & firing videos. 😊😊

The piece is incredible! I bought it as a gift, I cannot wait for them to receive it!
The colors are vibrant, the cube shapes are nicely pronounced and the handle is so comfortable! I am impressed!
Customer service is also amazing. Curt from Hammerly Ceramics replied within 20 minutes of me reaching out with a question.
I am very happy with my order and the whole experience, if you like something in their store just buy it!
