Acquired: Fulham Pottery ?oxide P184

Recommended Posts

Hi

 

I've been gifted some glaze materials and one of the sacks has a worn out label.  The bits I can read:

 

Fulham Pottery

xide

P184

 

It's a rusty red powder.

 

Anyone got any old (very old) catalogues and could identify this for me. 

 

Many thanks

 

Ann

I have no idea but my guess is its  an oxide or a frit with the P154#. Most frits are whitest in color so maybe not.

Many times when we get old materials from years ago they are almost worthless as they no longer are used in most formulas.

I would test it by making up a 3-100 gram test clear cone 6 glazes and adding 1,5, & 10 % to each to see what you get.

It might be iron oxide, it could be a iron rust glaze.

This will help identify what you may have.

fire in your next glaze firing and see what you have

The clues are the rust red color and the "xide" on the label.

 

There are few materials that are possibly "rusty red".

 

From the "xide" .... it is likely saying it is an oxide.

 

How many oxide forms of materials are something that could be called "rusty red"?

 

Iron oxide, for sure.

 

Red lead.

 

Red copper oxide

 

Anyone think of any more?

 

Is the "P" code there possibly indicating lead (as in Pb)?

 

best,

OK here's another idea. weigh out, on a gram scale, a small container,a (soda)cap full level to the top of red iron oxide, then the unknown material. If it's red lead,it's likely to weigh far more in comparison to RIO. if it weighs almost the same, the difference is accounted for in the way the materials were placed in the  cap

If you compare several different materials, say zinc oxide or strontium carbonate to silica or whiting or feldspar, you'll sone notice the relative weight of different materials.

 

Another idea, place a small amt of the red material on a sheet of paper and put a magnet under the paper and see if any or all the red oxide  is attracted to the magnet

Chilly,

 

Try http://groups.yahoo.com/group/clayart/message/269988

 

... of the previous suggestions of red iron oxide, red lead and red copper oxide

it only mentions red iron oxide, but would help confirm it (if true).

 

http://www.wikipedia.org will give densities of solids, which should also give an idea

of the relative densities of the powders (assuming that they all pack similarly).

http://en.wikipedia.org/wiki/Red_iron_oxide

http://en.wikipedia.org/wiki/Red_lead

http://en.wikipedia.org/wiki/Red_copper_oxide

 

AFAIK red iron oxide is not [strongly] magnetic, unlike black iron oxide.

 

BTW red copper oxide will give black copper oxide on firing (in oxidation).

 

Regards, Peter

hi,

I do have a Fulham Pottery catalogue, and sure enough as Jonh says FP, stands for Fulham Pottery,

and FP 184 is Iron Oxide-red , ferric oxide.

Fulham used to be at 210 New Kings Road, London SW, and I read it was established in 1671!
