I recently toured the Belleek factory in Ireland and found that they use gum of arabic in their clay body to be able to make those delicate and intricate basket forms.  The gum of arabic apparently allows the clay to be more pliable and not crack while forming the basket shape.  Does anyone know the process and proportions for adding gum of arabic to clay for this purpose?

Hmmm....That's interesting.  My college instructor, told me stories of people using caulk in their clay bodies, to make long coil strands.  It's basically the same idea, only I think the caulk burning out, would smell a lot more than gum arabic.

Gum arabic disolves in water, so with clay you probably don't need much, just wedge some prepared Gum into the clay and make it homogenous and you shouldn't have a problem ...

 

Dang it, now I want to try it.

Patty,

 

from Potterycrafts

http://www.potterycr...030010/P3382-05

 

Gum Arabic
An alternative to glaze binder it may also be used as a plasticiser - (2.5 % of the dry

weight of the clay) for increasing the dry strength of bodies.

 

Regards, Peter

Oldlady,

 

The picture in the Potterycrafts reference does indeed seem to be a bag of clay,

and selling gum arabic by the 5kg bag seems strange in itself. However, I expect

text I quoted on the addition rate is still what they meant to say.

 

Gum arabic tends to come as lumps:

... or as a powder:

How does this compare to using paper clay?

The Potterycrafts catalogue/website is littered with similar examples: (e.g. take a look at the Amaco Potters Choice glazes, there's probably seven or eight that use the same pic).
