2 layers of 650

[dubmblond]

Hello
I made some leaf prints that turned out to thin (650 clay). After firing I tried to paint over a new layer of clay (also 650).
After burning the two layer had only partly joined and partly curled away and did show shrink problems.

A'm I correct (after reading info on the site)that I can onley solve such a problem with the help of the oil paste?

Thanks dubmblond

Oil Paste would certainly be a way to go - although I am concerned about detail loss.  If that won't be a problem, get a decent layer on your piece and make sure it's dried well before you fire it

It sounds like you are torch firing, so this is a delicate process for torch work.  I might use more thinner layers.  If you hold the firing temperature for a longer time, you may get a better bonding - You don't want to get hotter, just hold it longer in .
When you are working pieces like this and you are adding on to already fired metal, don't do any of the finish work - no brushing or burnishing - the add ons will bond better if you don't.
Hope this helps

Thanks for your reply
The layer might have been to thik (trying to get is the right thiknes in one go) and yes I had wire brushed it already

I'll give it a go :'>

Frequently several thinner layers work better then one or two thick ones
good luck with it
