Re: agar sizing
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 90°C to dissolve it. However, I will check these days.did you note if it still has adhesive power round 40° ? 8 - )
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.is it yellowish or it has other "nuances"?
