  • Quickly Wet-mixing Multiple Additive Tests

    @ceramicmaterialsworkshop‘s “Understanding Glazes” course uses the following method to quickly mix variations of a glaze using one batch of base glaze and nine different types of additives (e.g. cobalt, copper, iron, stains) in two different amounts each.  It’s a really simple way to learn how different additives like colorants and opacifiers affect a glaze.

  • Glazy Video Tutorials

    New video tutorial “Creating Analyses & Deriving Recipes on Glazy.” In this tutorial, we’ll use Glazy ( to create an analysis of an ancient celadon glaze from Nigel Wood’s book “Chinese Glazes”, and using that analysis create an actual glaze recipe that we can test in the kiln.

  • Can you leave Jingdezhen?

    “Can you leave Jingdezhen?” This has been an important question for me during over a decade of study in Jingdezhen, China. In the “Porcelain Capital of the World” it’s easy to find anything you could dream of- the whitest, most translucent porcelain clay, glazes of all types and colors, kilns of all shapes and sizes. […]

  • Mary Fox Pottery

    Through Glazy I’ve met amazing people all over the world, most recently @maryfoxpottery It’s impossible to even begin to represent this artist through a few images in an IG post.  A self-taught potter who’s supported herself through ceramics since 1979, it’s astonishing to me how a single person can be so prolific, simultaneously producing multiple lines of […]

  • Colored Mason Stains in Porcelain Slips

    I’ve added some simple slip recipes to illustrate how one can use the Mason Stains added yesterday.  These slip recipes use a material called “English Porcelain”, which is simply an analysis of a typical high-fire porcelain body, as well as 8-10% added Mason Stain.  I hope you will add color tests, too! You can find these slips […]

  • Mason Stains added to Glazy

    Double Rainbow!  I’ve just added 60 Mason Stains with photos.  Just click “Materials” and search by the stain number, e.g. “6600”. In order to use a material in your recipes, you’ll need to add it to your inventory by clicking the “Add to Inventory” button.

  • Crazing: Fixed Glaze, Variable Body

    Here’s another test with fixed glaze and variable body.  The glaze is @pete.pinnell Pinnell Blue Celadon (a fairly low-expansion glaze that does not usually craze on porcelain bodies), while the porcelain is a typical high-fire body with Red Iron Oxide (RIO) successively added in 1% increments. Fired in a reducing atmosphere to Orton cone 10. Without RIO, this glaze […]

  • Adjusting Clay Body to reduce Crazing

    (Disclaimer: I’m not a clay body expert!) Rather than a biaxial with changing glaze chemistry applied to a single clay body, here is the opposite:  A biaxial with fixed glaze (Nigel Wood’s Jun) and variable stoneware clay body, with increasing Alumina moving up and increasing Silica to the right.  This test demonstrates that crazing is a function […]

  • Val Cushing’s Handbook

    Repost from @alfredceramics.  Leave it to the amazing people at @alfredceramicsto turn test tiles into freaking ART!  These are the most beautiful test tile photos I’ve ever seen.  @earlyamericanrobotpotteryblew my mind: “We’re using these glazes on our artwork, so why not photograph the tests the same way we photograph our ceramics?” The completed sets of cone 6 and cone 10 […]
