[Clayart] Liquid latex

Ginger

You are not getting a lot of answers perhaps because we don't have the 
answers.

I've worked with latex but I have never tried to thin it. Since it 
washes off with water, I would try water as a thinner first.

The one thing I do know about working with latex is the need to soap 
your brush; some people dip in liquid soap, or you can rub your wet 
brush on a bar of soap.

And I know it is important to build up a thick enough layer that it will 
peel off without tearing.

I've worked with a couple of brands, most recently Laguna's. In the old 
days it smelled like ammonia but it doesn't any more, thank goodness.

I have seen students successfully apply liquid latex over an underglaze 
and peel it off without removing the underglaze. I'm not sure if you can 
peel it off a glaze as successfully.
