Hi Everyone,
What is the best additive to minimize marring glazed surfaces while
handling.
I have read several descriptions of products but none address the
hardening issue.
Flocs?, APTII? These products seem to provide suspension and glaze flow
improvements but do not talk about hardening the chalky glaze surface.
Is there a protective "dip" that can be done to protect a glazed
surface yet allow additional layers to be added?

VeeGum Cer is used for this purpose. Contains clay and magnesium. Use up to 1 1/2 percent

Dan,
CMC can help too.
Hope it helps,

I have written this before and it always seems to raise questions. I add
1/4 or 1% powdered CMC to the dry ingredients of my glaze before adding the
material to hot water. It provides a hard surface on which I can paint with
watercolor effects using glazes and Mason Stains without any powdery
residue. I use less water also as the glaze becomes deflocculated. The CMC
does not mold in this glaze that sits for a period of time in a laundry tub
between glaze sessions.
You can see my painterly techniques on a few of my older pieces, landscapes
and face plates. I have practiced this for many years.
Regards,
Bonnie Staffel
