Starch sizing for Gum

I read in John Carroll's Photographic Facts and Formulas (1976 edition)
that:

"The paper may also be sized with a fairly thick paste of laundry starch
instead of the gelatin, and some workers prefer this method." (p313)

But that's all it says, does anyone have any further info on this method
of sizing? I work at a dry cleaners so I can take all the starch I need
free.
