16oz Voronoi Mug

Sale price$150.00

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: 16 fluid ounces (475 ml)
  • Height: 4.25 inches (11 cm)
  • Width: 4 inches (10 cm)
  • Material: High-fired Porcelain
  • Microwave: Yes
  • Dishwasher: Yes

The Voronoi texture covering this mug comes from mathematics, the same pattern found in giraffe spots, biological cells, and honeycomb. Irregular polygons that fit together without gaps, each one a different size and shape. The glaze settles differently into every cell, so the surface appears as both structured and organic at the same time. No two come out of the kiln the same.

Every Hammerly Ceramics piece is handmade by Curt in his studio outside Denver, Colorado. Starting from a prototype designed in 3D modeling software, each design has custom molds produced in-house. The HC logo is cast into the bottom of every mug alongside the year in which it was crafted. These unique molds are cast in porcelain, fired, coated in handmade glazes, and high-fired again in a custom computer-controlled gas kiln.

Each mug is made to be used, designed to be as comfortable and pleasing as possible, and finished in high-quality, beautiful, colorful glazes. Made from high-fired, strong, durable porcelain, food, microwave, and dishwasher safe.

I absolutely adore this mug! You can tell that he takes pride & time to make sure that these pieces come out to perfection. I've been following Hammerly Ceramics on insta for a while now & was always too late to a drop to grab the items that I wanted, but I was super lucky to grab 3 this time around & I'm in love with them! I will be purchasing more in the future.

I have ordered from Hammerly before and his work is beautiful! Plus he always packages for shipment so we'll it takes about 5 minutes to actually get to the item! More small business should follow his example!

This is my mother's day gift from my fur baby, much to my husbands surprise (he shops a lot while he's sleeping). This is absolutely my favorite mug now. It's so pretty I almost don't want to use it (but I absolutely will!)

It's one of my favorite mugs, the handle is perfect and it's just the right weight. The only drawback is I worry one of my family members will break it!

I love the mug.
It arrived well packed and is enjoyable to use. Colors are ad pictured. Of course the glaze is slightly different than the photos, but this is expected with glazing. I have received a couple compliments (this mug and others).
