  1. Wanted to update this thread with a link to a facebook page that shows the work of modern day Egyptian faience (Iranian faience) potters: خرمهره kharmohreh. Blue beads. Iranian Faience This post shows fired beads still embedded in the cementation glazing powder: fired beads in cementation glazing powder This page appears to be public and available for all to view, so you shouldn't need a facebook account to view it. Lots of photos of beads and more with that brilliant blue glaze.
  2. Just wanted to second some of what's been said above. I have an AIM 84J test kiln, purchased secondhand a few years ago. (I bought it from the original owner, who never actually used it.) It's a manual kiln; I added a plug-in digital controller later. It works great and I've never had any problems with it. The digital controller has made all the difference in controlling the firings - definitely worth it!
  3. Hi Reza, It is interesting to know that you are coming at this from a materials science point of view. You may already know this, but one author to look for is Pamela Vandiver. She has done a lot of research on Egyptian faience from a materials science point of view. In case it might help someone else researching Egyptian faience, here are two books in particular to look for (as far as I know, neither of these books is available in digital format): Ceramic masterpieces: art, structure, and technology (this is a great book on the production technology of all kinds of ceramics; though i
  4. Hi Reza, I am very happy to hear that you are working on this! Hans Wulff is the person who observed and documented the cementation glazing process in Qom in the 1960s. (I should say he is the person who brought attention to this in the West -- maybe others have published information about this in Farsi or other non-Western languages? From what you've written it sounds like there are not many written resources about it.) Unfortunately, Wulff died shortly before the 1968 article I cited above was published. Here's an excerpt from a memorial article about Wulff: Wulff, in fact, had ju
  5. I'm glad you liked the article, Marcia. Other than the beadmakers of Qom, Iran (here again is a photo of their donkey beads), the only person I know of who works with this technique is Jochen Brandt, and I don't really know a lot about his work. You can see some nice photos of a workshop he gave last year in Turkey here (hat tip to Ester Svensson). I would love to know about anyone else using this technique.
  6. Hi Reza, Since you quoted my response about cementation glazing, I'm guessing you might be interested in that. Cementation glazing involves placing small items (such as beads) in a container full of dry glazing powder. The glaze results from an interaction that occurs during firing between ingredients in the paste of the small item and ingredients in the dry glazing powder. This apparently ancient glazing technique was only (re)discovered and documented by researchers less than 50 years ago and there is not a lot of information available about it. The references I gave in my response above
  7. Just wanted to say that with the kind of glazing I'm talking about above -- cementation glazing -- the objects to be glazed are placed inside a container full of dry glazing powder. The glaze develops from an interaction between the object and the glazing powder during the firing. After the firing, the glazed objects break away from the remaining powder, which is friable and separates easily. This is one type of glazing of Egyptian faience (sometimes also called Egyptian paste) objects. Deb -- I wonder if your student tried this cementation glazing method, or if you are maybe talking about

  9. Not sure if this is what you're referring to, but there is a technique called "cementation glazing" that calls for placing small items such as beads in a container full of glazing powder. The powder nearest the items forms a glaze when it is fired. After firing, the glazed items break away easily from the remaining powder. This type of glazing is useful for items on which you don't want any firing marks or glaze-free areas (like beads) -- the glaze covers the item completely. This technique has been used for a long time in Iran; it is sometimes called the "Qom technique" after the city whe
