Always do your own research and discuss firing with your studio manager/technician! So, here I am again with my second test of the vinegar and bicarbonate of soda experiment on bone dry stoneware clay. This acid-base combo produces a chemical reaction that creates carbon dioxide (the fizz), water, and sodium acetate (the white residue). 👩‍🔬 This time I’m trying out the following oxides and glazes on the bisque fired piece (not to mention my first try at voiceover - be kind!), rather than going all in with copper oxide as I did the first time. 🤦 A - manganese dioxide B - red iron oxide C - copper oxide D - white lava glaze E - matt white glaze F - transparent glaze The results are so interesting! I’m pleased with how the oxides look with less liberal application wiped back, the craters show through nicely.🌕 The glazes haven’t really had much of an impact. But what’s really interesting is that in between the test areas where I didn’t apply oxide or glaze, there is a visible lava-like, shiny glaze! 🌋 I think that where the sodium acetate was thickest, it’s fluxed and has effectively created its own glaze! It’s not what I expected at all but it’s still an interesting effect with future potential for my work.😃 Are you a potter that’s tried it yourself? Let me know if it worked and your results. 🏺 🏺 🏺 🏺 🏺 #pottery #ceramics #ceramicart #modernceramics #textureobsession #instapottery #ihavethisthingwithceramics #potterystudio #ceramicreview".
