This must be the second part of a workshop. I wish he had explained what kind of slip he dipped his pot in. The result is amazing and so is his technique to keep top and bottom clean.
charlie is superb at this. That is just a painters tape he uses. the slip is a PIA to use in that it will flake off without regard of who is using it. It is a simple formula...just google charlie riggs pop off slip. I try it and have had some luck, but not as much as I would like. I keep trying though.
Hi, very impressive tecnique. From video I'm not able to understand which is the material for one step covering the object and the temperature to reach. Could you write them? thanks in advance, nicola (italy)
wouldn't call this demonstration a "reality show", it was a recording of pure reality. And, oh well, at least most Americans DO express their enthusiasm, whilst the "average European participant" just stands there, and says nothing....
I cant say what they use, but this is a white Crackle raku glaze, I think there are several recipes. Here is one from the Ceramics Arts Daily website: Ferguson’s White Crackle Raku Glaze Gerstley Borate 65% Nepheline Syenite 15% Tennessee Ball Clay 5% Tin Oxide 10% Silica 5% We fired ours at 1800 F between 20 - 25 min
williamson design Thank you! So I make that glaze, than dip the bisc fired pot, and at the end it comes out white with cracled? Do I have to put something beetween the bisc and the glaze?
Im not 100% sure how this one here is made. Some have different techniques. But I can tell you the way I did it when I was firing Raku in College last semester. Use this glaze on a bisqued piece. we fired to 1800 deg F. Firing time was around 20 min, or until the glaze was smooth on the piece. We removed the pieces one or two at a time and the students would cool them with hair dryers set on the cold setting until you see fine cracks in the surface of the glaze. then we placed them in a metal trash can with newspapers on the bottom, waited for it to ignite on fire, then trow in shredded paper, and put the lid on the can. Wait about 10-15 min and remove them. The black smoke from the smoldering paper permeates the small cracks made in the glaze by the hairdryer and darkens them permanently. Any areas not glazed will turn a smoke/dark smoke or black color. Hope this helps
