Looking For A Reliable Emmanuel Cooper Transparent Earthenware Glaze 1050'c Recipe

Recommended Posts

Hi if anyone happens to have Emmanuel Cooper's glaze recipe book on a shelf in their studio-

trying to look up recipes online but just will not go my way...

 

Just looking for a reliable  transparent earthenware ( 1050' celcius)  glaze, the glossy the better

 

If anyone happens to have a few minutes to spare!

 

with thanks

Hi Sputty, thanks for your reply

The glaze is going over velvets but its bowls that children will be painting themselves

so not really into using lead :(

If was sculptural, decorative etc, wouldn't mind but not for functional bowls

Is indeed a simple glaze recipe!

I use 90 Ferro Frit 3124, 10 EPK, and 2 bentonite, fired to cone 03. Cone 04 will work too, you may be able to go even lower. If it crazes, substitute some Frit 3249 for the 3124. Be sure to test because the chemestry of the frit may not be compatible with some of the underglazes. Other than that this is a super easy and reliable lowfire clear.

sine, i am in the USA and know i have seen that book in public libraries.  i can try to find it here and if you will identify the glaze in some way, i would be happy to copy it or them for you.  even if it is not in the st petersburg, fl library, it may be available on a loan from another library. 

 

finding it on amazon so i have the details at hand would be helpful.  i will look.

 

found a copy in clearwater, title, the potters book of glaze recipes,  dated 1980, 207 pages.  is this the one?

Thanks Oldlady! thats the one 1980- an excellent and very handy book to have, even as a starting point for a certain glaze.

I know there can be huge differences in materials between Usa and Europe and there are similar type materials

I don't usually glaze at all in my own work, so am very out of date with the equivalents!

Thanks again :)

Bciskepottery- thats exactly what I'm looking for

Thank you for taking the time- you're a star :)

 

the last recipe one sounds ideal- the glaze will be on white earthenware clay with 

underglaze velvets painted on.....

 

Thanks again 

ps. I will some day get my own copy of the book :D
