This inspirational art quote does not exist. Thes This inspirational art quote does not exist. These quotes were genearated by a huge language model from OpenAI called GPT-3.  After prompting the model with real quotes by famous artists like "Art is a line around your thoughts" (Gustav Klimt) and "To be an artist is to believe in life" (Henry Moore), GPT-3 responded with a wide range of its own quotes.  A small percentage of the generated quotes were plagiarised ("We don’t make mistakes, just happy little accidents." – Bob Ross).  Most of the quotes were trite cliches like "A picture speaks more than words ever can."   Out of about 40 responses, here are three of the more interesting quotes.  I have attempted to verify they are not plagiarized by searching Google for the entire quotes as well as sentence fragments. #gpt3 #art #artquote #craft #ceramics #pottery #art #machinelearning #generative

These texts are generated by GPT-3, a huge 175 billion parameter language model from OpenAI that creates responses to short textual inputs.  I've been accessing the model via AI Dungeon (https://play.aidungeon.io/) a text adventure game powered by artificial intelligence.  It's kind of like an endless "Choose Your Own Adventure" book.  (To access GPT-3, you'll need to sign up at AI Dungeon and turn on "Dragon" mode in the settings.) Here are some of the responses to my questions about Ceramics and Art.  (My input in bold.) #gpt3  #craft #ceramics #pottery #art #machinelearning #generative #generatedceramics
Chrome Tin Glaze with Increasing Chrome Oxide Fro Chrome Tin Glaze with Increasing Chrome Oxide From the earlier post, I've selected the Si:Al 9.5 ratio column to perform further testing.  The first biaxial test only used 0.05% Chrome Oxide, now I want to see what happens if more is added.  So the two variables for this biaxial are Al2O3 and Cr2O3.  At 0% Chrome Oxide, these glazes are actually quite nice Tin Whites.  At only 0.04% Chrome Oxide, suddenly there is already a lot of color.  Further steps in increasing Chrome are not as dramatic. With these past two tests I've looked at the role of Silica and Alumina as well as Chrome Oxide in a Chrome Tin Glaze.  But there are other important variables, like the role of the fluxes, determining the best amount of Boron, as well as Tin Oxide. Luckily, someone has already looked into some of these factors.  David Tsabar (@pricklypotter https://glazy.org/u/davidtsabar/) has published some wonderful blend tests, the first swapping Whiting with Dolomite, the other gradually increasing Tin Oxide.  From his tests we can conclude that CaO works well as the primary alkaline earth flux.  And 5% Tin Oxide seems to be a good amount for promoting color.  You can view his work at https://glazy.org/recipes/26787 #volumetricblending #theglazyproject #craft #glaze #glazes #glazerecipes #glazetest #ceramics #pottery #ceramicglazes #glazechemistry #glazechem #glazecalc #umf #glazy
Effect of Silica & Alumina on Chrome Tin Glaze Gl Effect of Silica & Alumina on Chrome Tin Glaze Glazes depend upon a variety of factors, one important one being the levels of Silica and Alumina (and the ratio between the two).  This biaxial shows that by simply varying the amounts of Silica and Alumina, we can acheive different glaze colors and surface qualities, even if other variables, including the amounts of Tin and Chrome (which give us the color), stay the same. This Si:Al biaxial for cone 6 oxidation has set flux ratio of 0.16:0.84, fixed 0.18 B2O3, and 0.09 SnO2.  0.05% by weight Chrome Oxide was added to each.  200g batches of the four "corner" glazes were mixed & sieved, and volumetric blending was used to create the intermediate glaze tests. EDIT: The image should say +0.05 Cr2O3, not Cr2O #volumetricblending #theglazyproject #craft #glaze #glazes #glazerecipes #glazetest #ceramics #pottery #ceramicglazes #glazechemistry #glazechem #glazecalc #umf #glazy

To be honest, I rarely think of how much materials To be honest, I rarely think of how much materials cost.  But one of the most valuable things that @redlodgeclaycenter is teaching me is how to become an actual professional, and that means keeping an eye on the bottom line. You might not know this, but Glazy can be used to keep track of your material costs.  For these Red Lodge Clay Center studio glazes, I've used Glazy to create batches of 10kg (which fills a large bucket) and come up with some surprising results.  I expected the glazes with high amounts of Mason stains to be expensive, but not four times as expensive!  And the lovely Val's Matte Orange Tan surprised me the most:  Val's glaze doesn't have any stain, but due to just 8% Lithium Carbonate it's our second-most expensive recipe! In coming posts I will show how to enter material costs and calculate batch costs in Glazy.  Then I will test glazes and propose replacements for Red Lodge's top-three most expensive glazes.  Ideally a 10kg bucket of glaze should be in the $20-$25 range. #craft #glaze #glazes #glazerecipes #glazetest #ceramics #pottery #ceramicglazes #glazechemistry #glazechem #glazecalc #umf #glazy
The amazing @redlodgeclaycenter has generously all The amazing @redlodgeclaycenter has generously allowed me to share their studio glazes on Glazy. https://glazy.org/u/rlcc/recipes (link in bio) Studio glazes often reflect the history of a studio.  They are brought in by a succession of studio technicians from their schools or places of previous employment, and the recipes go through a process of "natural selection". Those that are unreliable are gradually weeded out, while those that are loved for their beauty by the students may remain. For the next few days I will be doing a series of posts related to these glazes. #craft #glaze #glazes #glazerecipes #glazetest #ceramics #pottery #ceramicglazes #glazechemistry #glazechem #glazecalc #umf #glazy
