AWPottery Posted January 13, 2014 Report Share Posted January 13, 2014 I signed up to take a Naked Raku class at my local community arts center that lasts for a few weeks. Anyways, I wanted to make the most of my time in the class and wanted to get some pots ready before the class began. I've never done naked raku before and was wondering if in preparing some pieces to get ready for the class my understanding is that you put terra sigillata on the pieces when leatherhard and burnish them before being bisque fired. Is this correct? Also if I leave some part of the pot without the terra sigilata on it (just the raw clay) in the firing it will turn black correct?

Babs Posted January 13, 2014 Report Share Posted January 13, 2014 naked raku , Marcia wil give great details in a minute, I remember is when you apply glaze in patches to your pot. This glaze is formulated so that it drops off when the pot is immersed in cold water.thus leaving lovely white "patches" where it had been placed on the pot. The black areas are formed where the clay was left unglazed in the reduction phase. The glaze is dropped off after this phase. Marcia and other raku people wil give details. Burnishing and terra sig. will give a lovely smooth satin finish to your po don't think it is esssential to naked raku.. Link to comment Share on other sites More sharing options...
Up in Smoke Pottery Posted January 13, 2014 Report Share Posted January 13, 2014 the Terra sig is applied to the leather hard or drier vessel. I typically do 2 - 3 coats then burnish with old nylons. In naked raku, the black areas are the areas that the smoke hit regarless if it is bare or terra sig'd. The bare clay may be more difficult to remove the fired glaze /slip layer.

ayjay Posted January 13, 2014 Report Share Posted January 13, 2014 The way I understand the term *Naked Raku" is this:- bisque fire pot - apply porcelain slip - apply glaze - you can leave as is or can sgraffito designs through the glaze - raku fire - reduce in sawdust (or whatever) - when cool the glaze is chipped off and will show black areas where the glaze has crazed or been removed manually.

Marcia Selsor Posted January 13, 2014 Report Share Posted January 13, 2014 Lots of different ways to do things. My favorite Naked Clay potter is David Roberts, author of Painting with Smoke http://ceramicartsdaily.org/ceramic-glaze-recipes/raku-glaze-recipes/peel-away-slip-recipe-for-raku/ I have one of his pieces from when we were both doing workshops at Kelowna, BC along with Randy Brodnax and Don Ellis, Cathy Jeffries, and Les Manning.I was teaching an Architectural Ceramics class. David has a different recipe than the one below, but his process is after removing the slip to expose the pattern, he polishes the surface with diamond pads to remove all the rough remains. It give the piece the feeling of smooth stone. ***watch out when you google Naked Clay...you can get a lot of porn The slip, sometimes a slip with a thin coat of glaze, is fired and then peeled away.Linda and Charlie Riggs sometimes do this too.
