&gt;Powder and lump are both fine, but powder you can use immediately.
&gt;I whip
&gt;it up in the blender a couple quarts at a time. That said, I saw my
&gt;Sam Wang stir the gum powder right into his pigment/water/dichromate
&gt;mix and
&gt;brush his coat on!
&gt;I have never used gum in lump form, but it is said it takes a day or
&gt;two to
&gt;dissolve. I am not sure if this is true from firsthand experience.
&gt;is a big can of the lumps in our grad studio, so I should see.
&gt;If you already have formalin, use that. I used to not size my
&gt;paper, but
&gt;sizing produces very predictable results and prevents pigment stain.
&gt;Try no
&gt;size, and if stain haunts you, then size.
