what about pva sizing?



Hi all...

What about using Gamblin PVA size?

I know that Jim Larimer likes to use it for gums...has anyone else used it for pt/pd or other processes?

I'd like to buy a bottle today and try it out...

Paul

Damiano,
did you note if it still has adhesive power round 40 ?         8 - )
I think you mean if this happens after a warm soaking, like for resinotype. I don't believe agar swells like gelatin, because you need to rise the temperature up to 90C to dissolve it. However, I will check these days.
is it yellowish or it has other "nuances"?
I have a yellowish agar, given me by a biologist, and a perfectly white (edible) agar bought in a grocery. But also the yellowish one, once brushed on the paper and air dried, is only barely visible but for the shine of the sheet.
