Hey Thanks for watching! In this video, I show you how to make a marble effect with shaving foam on a bisque fired work. The video is real time. www.caldersceramics.com Instagram: @calders_ceramics Etsy: etsy.com/shop/caldersceramics
This is an awesome idea. How soon after rolling the piece in the foam/ glaze, do you wash it off? Couldn't you fire it AS IS: as the foam would just burn if in the kiln?
@@kevinjamiesonbelou so what glaze you use? Botz or others, names please and I am interested in time too, it’s strange that glass stacks on cap so good and not falling with water….🤔 looks like you made a second firing on kiln;)
I don't think that will work, the underglaze has to dry before washing off the shaving foam. I don't think this will happen when the clay is still wet😅
So cool! Do you recommend a specific brand/type of glaze? I thought Duncan covercoat was the one to use, but now that it's discontinued I'm wondering if another type would work.
Thank you for this video. Tried it and it is so much fun! The only problem - clear glaze did not stick to the piece after shaving foam. How do you glaze it? Thank you for your response in advance. ❤️
The piece is only bisque fired, so it is still very porous. The underglaze is like a dye suspended in water that is sitting on top of the foam. Wherever the piece touches glaze, there will be an instant connection and soaking in that draws the color into the clay body. It would be very difficult to get back out, if you wanted to. It could smear if you wiped it clean, but rinsing the foam off with running water allows the underglaze to stay in place almost completely.
I just tried this with porcelain, and the water washed the underglaze away. I rinsed, dried and tried again later that night. Scraped the shaving cream with my hand this time. It came out VERY light. But I love it.
We tried this technique with Duncan Concepts - so far every project has fired out with many "glaze pulls" Have had the ladies re-clear glaze & fire to fix the problem. Any idea why this happened?
the shaving foam likely has moisturizing ingredients that are acting as a resist on the bisqueware. It's like putting on lotion then handling bisqueware (glaze will crawl from the areas your hands touched. Dust does the same. This would be a better technique for people who glaze fire raw OR if you re-bisque. Hell, even doing this on greenware would be better than bisque
So first you use a bisque piece which is baked at 1000°C and after you used the technique with the foam you wash it off and you use the glaze fire at 1220°C? I need to be sure because I study to be a art teacher and I love to work with ceramic and I would like to give it a try but I am not really good in ceramics yet!!
Yes that's right! But I do my bisque at 1020°C, but 1000°C is good as well. After doing the shaving foam technique I also apply 2 coats of clear glaze, this makes the pieces foodsafe and makes it shiny😊
I tried this the other day. It worked really well until I applied a clear glaze over the top. The area where the shaving foam had been resisted the clear glaze. Created a bit of a messy finish. Have wiped off the clear glaze and may have to leave the outside of the piece unglazed
I fire twice - first fire the underglazed piece (can go with bisque or 04), then add clear glaze and fire again. Adds time and effort, but this way the underglaze (and shaving foam) isn't competing with the clear glaze.
What IF you used a tray of white underglaze instead of shaving cream??? Then you wouldn't have to wash off anything.. same beautiful effect... maybe even more interesting texture....... :)
Hello, Thanks a lot for sharing. Sorry but I'm not sure that the washing the piece you can save the colours. To my opinion, it's not possible. You can not get the beautifull effects you show.
