A question about sanding clear glaze over underglaze-decorated mug and refiring


Recommended Posts

Hello! This is my first time asking a question here, I hope I’m doing it right!
 

I decorated a mug with underglazes and then applied two thin layers of brush-on clear glaze. I believe my piece was over fired as the colors came out way darker than my test tiles. I’m really not liking this piece and was wondering if I could salvage it instead of trashing it. Could I sand down the clear glaze, repaint the underglazes and fire again? I was thinking of firing to cone 04 instead of mid ranging it to 6 again.

Thank you for any help!!

you might try this but the time you spend on it will be more than the end product is worth.    there are lessons to learn every day.   it might be that if you keep the items you dislike today, there may be a day they look perfectly OK.

Or better, the day when someone comes by and offers you twice as much as you thought it was worth.

Unless of course you're making something to match something in your house on purpose.

I think the largest problem may come from a build up them of the more refractory underglazes.

Get them Cone Packs in there so you can "believe" the truth!

Thank you both!! Honestly I love tedious detailed work so it wouldn’t be annoying for me to sand and repaint, but the more I let it sit there the more I like it. It’s a gift for a friend who is into a certain type of color scheme and these colors just aren’t right, despite my previous test tiles.

Unfortunately I don’t have my own kiln so I can’t yet control how it gets fired...someday! Thank you both again, I think I may just leave it as it is and hope my friend likes it. 
 

I’ll likely do a test someday where I sand down the clear glaze and repaint and refire just fer kicks!

Just remember:  You're sanding "glass" - so be sure to wear an appropriate respirator, and do your sanding outdoors or in a workshop with a good dust collection system.

And..  most underglazes are darker and/or stronger color with a clear 'top-coat' than when fired by themselves.   Were the test tiles you're comparing to finished exactly the same as the final work (same number of coats, of both underglaze and clear glaze) ?
