Egyptian Paste (aka Faience)

Experimenting in all facets of Egyptian paste, mixing clay, construction techniques, firing solutions, and finishing ie. cold working is in the scope of our discussion. Perhaps we will have time to get around to some practical uses of Egyptian paste, but mostly research into what works will with this media and what does not.

Simplest Mould, Drop Out Mold

The Potter's Dictionary of Materials and Technique by Frank and Janet Hamer recently came into my possession. It's a British publication. It is astounding how many pottery terms have different meanings. There may be a language barrier. I did get the feeling that Mould is used rather than Mold. You must forgive me if I used the two interchangeably here.
There are many different types of molds for clay material as well is different materials for making them. I'll begin with the simplest, that is a clay mold.

Starting with a rather thick slab of porcelain, pushing in a borrowed antique button collection this Mould was generated. It's just that simple to make a mold. This slab is bisque fired to cone 04 or 1800°F/1000°C.


Using it is an uncomplicated operation of taking a small ball of Egyptian paste and smash it in to the depression. Egyptian paste comes out rather easily until the mold becomes water saturated. Once the mould is water logged you may either set it aside to dry or dust it was a little cornstarch or rice flour to aid as a release agent.

In the image to the right shows a small slab of clay in which a screw was impressed. After being dried it was fired to approximately 1000°C. A small coil of Egyptian Paste was pressed into this form/mold and released. A straw was used to place a hole in the top of coil forming these beads. Pretty simple, eh?

Hi,
First of all I would like to say how great and informative this blog is! I first came across Egyptian Paste in August when I attended a summer school and since then have been fascinated by it. Your blog offers inspiration and motivation to explore further, which is fantastic. I’ve made my own drop out mould last week with some twigs I collected and –hopefully- will be making some beads later on. Unfortunately, the first recipe I was using created a very, very glossy finish which is prone to chip and break on contact with other beads, so I’m currently experimenting with different colorants and mixtures, although still using the same basic recipe. So far, my experiments showed that a cobalt oxide mixture produced a far glossier surface that a copper oxide mixture and I am still waiting on other combinations, which is really exciting. Anyway, thanks again for such an encouraging blog! Lisa

I love this blog, so informative, easy to understand and down to earth. I love the paste, and the colours you manage to produce even when experimenting. It's fascinating. You are all so inspiring, it makes me want to go out there and 'have a go' despite not having much knowledge of clay or the equipment. Please keep it going. Is there anywhere in the UK where I can buy the paste already made up, so I can play around with various ideas? Kaz

I've just started experimenting with egyption paste that was given to me by a collegue. I don't have the recipe at the moment but assume it's similar to others. When I let some overwet paste sit on a plaster bat to dry for several bours, I found it ate thru the top surface of the plaster. I suspect his means I can,t press paste in plaster molds... only bisqued clay. Have u had any experience with paste in plaster molds?

I've never worked with this material before. Do you have any idea if it is formed to be rather thin, would it be somewhat translucent?
Thanks,
