To Wash or Not to Wash, Your Kiln Shelves

Share |

While many individual customers report that they do not need to use a wash coat on their ADVANCER® shelves, we generally recommend using a suitable high alumina wash on ADVANCER® shelves – particularly in studio or classroom settings where multiple users are present.

Due to the extremely low porosity of ADVANCER (less than1%) vs. conventional silicon carbide (18% typical) and cordierite (30% typical), it is true that there is much less of a tendency for glaze to penetrate into or stick onto the ADVANCER surface. Never the less it is still possible for glaze to react with the protective oxide glass surface of ADVANCER, especially at higher temperatures, and bond onto the ADVANCER surface. Glaze drips are usually easily removed without grinding because extremely low porosity of ADVANCER. On the other hand, glazes that volatilize at temperature, leaving a fine mist of glaze on the shelf may require light grinding or sanding for complete removal.

Some people thought it was silly to fly to Italy to take a workshop from an American potter (Gay Smith), but I didn't listen to them. I learned a tremendous amount there, even when there were issues with materials and kiln size, we worked through them and as a result I learned even more. Specifically, we got to single fire/raw glaze, which I had never done before. I loved the result and the immediacy of the process.If you can't take 2 weeks off, or afford to go to Italy, don't fret. There are tons of great places in the U.S. that have great workshops. 2 weeks is the standard, but you can find 1 week workshops at places like Odyssey in NC or Castle Hill on Cape Cod. Just keep looking. There is also the Mid-Atlantic Clay conference in October that is a long weekend, and might be good place for you to go and experience a few different potters. Also the Art League in Alexandria and the Workhouse Art Center in Fairfax have weekend workshops. I think they are both having workshops in October. Check those out, since they are in your backyard. The weekend workshops tend to be demo only, but I still think they are worth it, and they are cheaper. The best advice I can offer is to go to as many workshops as you can. I credit workshops with helping me find my artistic voice. Also, and this is going to sound hokey, visualize what you want and accept what comes in your path. I have been doing that for the last year, and while I am still working that day job, I will cut back my hours in the fall to pursue more pottery. I used to resent that my job kept me from pottery. Now, I am grateful for it it allows me to do pursue this avocation without financial stress and teaches me good business practices that I apply to my growing pottery business. It's nice to meet you. If you ever get down to the DC area, let me know. And I'll keep you posted on the upcoming workshops I learn of in the DC area.Ciao.

It should take 12 hours to 14 hours to reach cone 6. If your kiln has turn up switches set the LOW setting and run that for 3 hours, then run the MEDIUM setting for 5 hours before turning the setting to HIGH.Since your pots are small and thin this firing cycle will not cause them to blow up or crack. Mechanical and chemical water from the clay is driven off at a slow rate.

As far as the proportion is concerned, what if you experimented with making the feet shorter or thinner? You could also work with the negative space in the handle by cutting the handle in half at the midpoint and have each part of the handle meet in the middle with the ends in a subtle bent curve. That would suggest flowing arms above the body.The form is so full bodied and feminine and having handles resembling arms could add dimension to the piece. Jacqueline
