Hi there, I'm new on this forum and quite new to ceramics and glazes in general so please excuse my lack of knowledge... I've been making ash glazes using this Katherine Pleydell-Bouverie nuka glaze recipe; Mixed woodash 33.0 Feldspar 33.0 Kaolin 16.5 Ball Clay 16.5 On a recent trip to China I aquired some rice straw ash and I was really excited to turn this into a glaze. From what I read rice straw ash should be very high in silica too like other (mixed) wood ashes so I used the same recipe. The results came out rather different then expected or other wood ash based glazes I made using the same recipe. It looks like the glaze didn't melt or run at all. Please see photos for your reference. It seems like there is a lack of silica and fluxed present in the glaze. I want to do some line testing by adding silica in 10% increments and another one adding flux like gersley borate but perhaps somebody here sees something I'm missing or has other ideas. The other thing that could be possible is that I misunderstood in China and I've acquired rice HULL ash instead of rice straw ash. I'm firing in an electric kiln on 1240 degrees and have gotton desirible effects with mixed wood ash glazes based on the same recipe and firing. Thank you for any suggestions or advice.

Hi everyone! I am currently experimenting with additional material, added to casting slip such as: sand, (rice) grains, paper, etc. I was wondering if anyone has some experience with that or can reference some interesting sources or examples to study? For some reason I do not find a lot (or any) examples of people working with these types of mixed media. Any tip or idea would be helpful! Thank you and I am looking forward to the feedback. Seb
