Added underglaze to a finished/ fired piece... should I fire again or...

[Roy Ceramics]

Hello,

 

I fired a piece with no glaze to see if my marbling technique worked- it really didn't pan out how I planned. not much of a marble effect happened- i think the two clay bodies were to similar.

So I decided to hand paint onsome  underglaze  ( black and white) to create a pattern. Should I fire it again ( a second time) or is there a spray fixative I can use on the underglaze?

I like the way it looks at the moment- matte painted underglaze and was wondering if a clear fixative would preserve it as is.

Any thoughts on which step to take or suggestions of a fixative?

 

Thank you all

Hi Roy and welcome to the forum.

Yes, I would recommend firing the underglaze onto the pot. Many underglazes remain matte when fired to bisque temperatures. Try a test tile with the same underglazes and fire that to see how they look.
