  • Paintings and pots!

    Alternate title: “Feet and pots!” I’m infatuated with @barnesfoundation and Barnes’ “ensembles”. The experience is overwhelming and incredibly intimate, at times mysterious and perplexing, and often imbued with a joy not unlike discovering a hidden gem in a vintage knickknack shop. As a ceramicist my favorite juxtaposition is these folk pots, mostly by unknown artists, fairly unremarkable […]

  • Kōgei: Art Craft Japan

    I was lucky to have landed in Philadelphia just as “Kōgei: Art Craft Japan” opened at @philamuseum. Here are some of the beautiful surfaces from those works. I included a wonderful detail of Jun Kaneko’s “Untitled Dango” that I believe is still on display at the museum. I love looking at work and asking myself, “How […]

  • Lasse Östman Golden Glaze

    Lasse Östman generously shared his deep knowledge of glazes on his website and social media.  The Glazy community has been working to re-create Lasse’s glazes, and two recent results from @trees_wijnands and @xavierescala are just too wonderful not to post.  It’s amazing to see people around the world sharing their knowledge like this!

  • Moon pebbles?

    Just realized I hadn’t finished editing tests from a couple years ago.  Here’s a line blend of gloop: Left side has +5% Mason 6097 stain, while the right has +5% 1000 mesh silicon carbide (SiC).  At around 4% it becomes a dimpled, smooth, stone-like surface that’s great to the touch.

  • Happy Pie Day!

    I love pottery that tells you exactly what to put in it. Check out @philamuseum‘s wonderful Pie Day post for more inspiration. “Cherry Pie” Pie Plate, Vickers’ Pottery, 1850Philadelphia Museum of Art

  • Pâte-sur-pâte

    Late-Ming Dynasty Two centuries before the development of pâte-sur-pâte (“paste on paste”) at Sèvres, late-Ming Dynasty Chinese potters were experimenting with a bold decoration technique using brushed slip. This type of Zhangzhou (or “Swatow”) ware employed white slip brushed in lively patterns on cobalt blue, iron brown, or even white backgrounds. The slip was vitreous […]

  • Ephemeral vessels

    I only just became aware of David Lebe’s work from a print featured in the Philadelphia Museum of Art’s new exhibition, “Elegy”.  The story of how Lebe’s “Scribbles” series came to be is incredibly moving, an artist struggling to find meaning in their work during the AIDS crisis:  “I had no idea what they were about, no thoughts […]

  • Happy Year of the Tiger

    To celebrate, I’d like to share with you some of my favorite ceramic tigers.

  • Marbling Gloop

    Some of you asked about how I made those marbled gloop tiles a couple years ago.

  • Phil Berneburg

    Some have passed on but left treasures behind.  I never met Phil Berneburg.  But recently I stumbled across a wonderful video explaining pyrometric cones, which led me to The Potters’ Round Table.  Almost 100 excellent videos of Phil explaining all aspects of ceramics, including gems like “Pottery Figurin’ (Math for Potters)”. I’ll link some of Phil’s lectures in […]

  • Let your customers know your ceramics are lead-free.

    This holiday season, let your customers know your ceramics are lead-free. Recently the NYC Health Department issued a warning about lead in “traditional ceramic ware” after a number of people reported lead poisoning.  As we know, there are no “safe” levels of lead exposure, so it’s good to see a health department doing its job.  Unfortunately, it’s […]

  • #glazepunk

    There are so many great punk genres (cyberpunk, steampunk, solarpunk, etc.), why not #glazepunk?! Ceramics is undergoing a revolution, and many aspects of current trends could be defined as “punk”: rejection and/or reinterpretation of authority and tradition; “hacking” ceramics with new tech like 3d printers and machine learning software; reverse engineering materials & glazes; breaking down […]

  • New Home

    Just drove 2,000 miles from #redlodge to #philly Looking forward to settling in, exploring the city, fixing up Glazy, and makin pots with @jacintta at @theclaystudiophl

  • Special Auction

    Bidding open!  I’m honored to be hosting an auction of Soojin Choi’s (@soojinchoiii) sculptures.  100% of the proceeds minus shipping costs will be donated to the Support the AAPI Community Fund. Just send me (@glazyorg) an Instagram direct message with the lot number and your bid.  (Please do not bid in the comments.)  I will respond with a message […]

  • Two Years of Tests

    Time to leave the residency, and there’s no room in the Uhaul. Sad to say goodbye.  But these tests live on in Glazy, backed up and safe.  Much like my book and music collections, my glaze collection is now virtual. Ceramics is in some ways inherently wasteful.  But Art is one of the things that makes us human, […]

  • The Color of Celadon

    With all its variations, what does the term “Celadon” even mean? There are various theories as to why Westerners started using the term “Celadon”.  Regardless, “Celadon” refers to a category of Chinese ceramics known as 青瓷 (qing ci).  瓷 is porcelain while the 青 (qing) in 青瓷 signifies a color (or range of colors). But exactly which […]

  • The Colors of Celadon

    Just a few examples of celadons, there are more like Plum Celadon (梅子青) not to mention Jun and Guan.  Color and surface can vary within each type, and even between time periods.  A contemporary Duck Egg Celadon that adds a small amount of cobalt in addition to iron for extra color is quite different from the Yuan […]

  • Fake Traditional Chinese Materials Blends

    Using chemical analyses and US materials, I recreated traditional Chinese materials like porcelain stone, glaze stone, and glaze ash.  Limiting myself to these “fake” materials, I blended them to create porcelain bodies and glazes. Here are two line blends of fake Sanbao Porcelain Stone and fake Yaoli Glaze Stone blended with fake Glaze Ash.  While both of […]
