#glazeapplication

From @suemcleodceramics who is always sharing glaze info! • • • • • Yesterday's post showed how a glaze applies differently when you have different water content (different specific gravities). 🤓 This post shows the difference before and after flocculating a glaze with Epsom salts. Both of these samples have the exact same amount of water (Specific gravity = 1.48). 🤓 Before the Epsom salts are added (left tile) the glaze is milky thin, the particles move freely past one another and don't stick well to the test tile. 🤓 When the glaze is flocculated with Epsom salts (right tile) the glaze is thicker in the bucket, the particles stick to each other and stick better to the test tile, giving a thicker layer. 🤓 The glaze also takes a bit longer to dry which allows for a smoother, even coat. 🤓 Flocculation and water content both affect how a glaze will apply. Every glaze will have different characteristics. It's good to get to know how all your glazes work so you can make them work the way you want. 🤓 . . . . . #testtiles #glazes #ceramicglaze #glazechemistry #glazetesting #glazetests #flocculation #flocculants #specificgravity #viscosity #understandingglazes #howglazeswork #glazeconsistency #glazeapplication #glazeworkshop #glazeworkshops #canadianceramics #yyjpottery #yyjceramics #vancouverislandpottery #potterymaking #ceramics #pottery #glaze https://www.instagram.com/p/BtpJ-qYhzbc/?utm_source=ig_tumblr_share&igshid=1x7qcy81arx2o

Thanks to Rose and Matt Katz of Ceramic Materials Workshop, I reformulated my Satin Matte glazes. However, I also learned that applying glaze to a test tile is not equal to applying that same glaze to a vase, bowl, or what ever else. I've been so reluctant to use any of my bisque pieces to test. I decided to just throw 1 lb cylinders, not spend much time on them, and use these to test application methods of my new glaze formulas. This way, if something goes wrong with the application I won't feel I lost $$$ because I glazed a piece intended for sale. . . . #glaze #glazetesting #glazetest #glazeapplication #ceramicsmaterialsworkshop #glazemaking #cmw #wheelthrownpottery #pottery #potterslife #potterystudio #clay #whatidoforaliving #selfemployed #avlartist #wncartists #clayart #ceramics #ceramique (at Gerton, North Carolina) https://www.instagram.com/p/CPlwgaCDfqb/?utm_medium=tumblr

DO NOT TRY THIS WITHOUT PROPER PROTECTIVE EQUIPMENT! . . This is a commercial low-fire glaze applied to a #bead made from my coffee inclusion clay that I fired on using a fresnel lens magnifier to focus the afternoon sun onto the surface of the bead to vitrify the glaze. The first image is of the bead right after “firing” and the second is after I washed off the unfired glaze. . I’d played around with using solar energy to work with glass before, and I knew that large focusing lenses were used by alchemists to harness the energy of the sun in their experiments. Many an alchemist also ruined their eyesight using them. . This is an extremely labor intensive way to glaze. With the page-sized magnifier that I used, this took me about five minutes. You could probably go faster with a larger magnifier, but there are other logistical challenges with using something that can’t be easily held by hand. Since you are focusing the sun onto a single point, you are for all intents and purposes gazing directly at the sun. For protection, I’ve been using a pair of eclipse glasses that I had bought back in 2017. . My thought was that I could do some interesting glaze layering by selectively sintering portions of glaze and then washing away the un-sintered parts. I wasn’t sure if I could get the piece hot enough to actually mature the glaze, but if I do it when the sun is at it’s peak, it turns out I can (geographic location and seasonal cycles of sun position will play a part in available solar energy). . I’m not sure where I’ll take this, but it definitely has me thinking in some new directions. . #ceramics #glazeapplication https://www.instagram.com/p/CDrjOXJH1Or/?igshid=1wwhynztru4kr
