Rutile - Earthenware

Recommended Posts

Evening all,

 

I was just wondering, does Rutile promote mottling and streaking or other interesting effects in Earthernware glazes approx. cone 04? Or does this just happen in stoneware.

 

Many thanks.

 

 

I think with the right glaze and flux, you should be able to get some interesting effects. The glaze, I would think would need to be a bit fluid and be used as a capping over a more stable base glaze.

 

You might test by glazing a piece with a know glaze then making up a wash with rutile and a frit like 3269 or 3110. Do a line test rutile 25 frit 75 and in 10% increments go to 75 rutile/25 frit.

Give it a try.

Hope this helps

Wyndham

Thanks for your advise, I'll give it a try.

 

I note you say 3110 which is a high alkaline frit and is commonly used in crackle glazes. If I do a wash with this is it likely to cause crazing of the below glaze?

 

Cheers,

Gary

These are just broad suggestions that you might try. There are several frits 3134,3124,3110, 3269 as well as gertsley borate, soda ash, wood ash and even crushed up glass.

I tend to test as many possibilities as possible in case I run into a great effect. Most will be failures but one or 2 might work very well.

Hope this helps Wyndham
