Mark C. Posted January 19, 2014 Report Share Posted January 19, 2014 I know there was talk about this in a earlier thread. I looked for that thread and did not find it. What was the consensus on how this is done. These pieces have stilt marks (ceramic stilts not steel) on bottoms so I know they where fired to a lower glaze temp most likely . My main wonder is how the holes are put in? Any ideas. Mark Link to comment Share on other sites More sharing options...
Norm Stuart Posted January 20, 2014 Report Share Posted January 20, 2014 I assume commercial pieces like this are slip-cast with the holes being raised areas in the plaster cast which are fettled off. I suppose they could be punched after casting as well. Doing pieces with this concept by hand is completely different, probably cutting tools and slip-trailing, although it's difficult to find the right stage of dampness where you can safely cut without the bowl collapsing. Magnesium crawl glazes can provide an irregular rice pattern. Magnesium Carbonate crawl over-glaze in a rice-like pattern. Link to comment Share on other sites More sharing options...

Norm Stuart Posted January 20, 2014 Report Share Posted January 20, 2014 Thanks Babs -- So that's what rice grain is. I've never seen anything like that before. Holes or thin spots in the porcelain bisque filled during the firing with a viscous glaze. Ever so difficult. Ferro Frit 3195 when fired to ^06 would be a viscous enough melt to act like this. Once again that same Chinese village of Jingdezhen, the 2,000 year old studio. http://gotheborg.com/glossary/ricegrain.shtml maybe this way.

Marcia Selsor Posted January 20, 2014 Report Share Posted January 20, 2014 Thanks Babs. There are many of these examples in museums and you can sometimes buy them in Oriental grocery stores. Marcia Link to comment Share on other sites More sharing options...
Babs Posted January 21, 2014 Report Share Posted January 21, 2014 I like to think that some careless potter did actually roll some clay and accidently collect a few grains of rice in it, raw lazed and fired it with wondrous results! Link to comment Share on other sites More sharing options...
Mark C. Posted January 21, 2014 Author Report Share Posted January 21, 2014 I have had these pieces and some more like it for over 30 years-I think they came from Vancouver BC from about 1980 in chinatown or little tokyo? i recently gave some away and was asked how it was done.

Norm Stuart Posted January 21, 2014 Report Share Posted January 21, 2014 Based on what I've read about Jingdezhen, I'd ask Mrs. Zhang. She seems to the person in that village with her fingers in every pie.

Amy Waller Posted January 21, 2014 Report Share Posted January 21, 2014 Related to this is Gombroon ware, a Persian fritware body that was sometimes pierced. It was possibly an attempt by Persian potters to imitate the translucency of Chinese porcelain. Then, later, Chinese potters may have been imitating the pierced Gombroon ware by making the rice grain ware.Here's an example and a little more information from the Ashmolean Museum:Gombroon ware bowl with foliage and pierced decoration Link to comment Share on other sites More sharing options...

Marcia Selsor Posted January 22, 2014 Report Share Posted January 22, 2014 Amy, Thanks for posting that. I finally made it to the Ashmolean Museum last Oct. It had been on my wish list for decades. One of the best ceramics Museums of the world! Marcia Link to comment Share on other sites More sharing options...
