[alt-photo] Re: PVA for SIZE & GUM ??

[geoff chaplin]

Thanks - that’s useful. Reading this and other material I'm guessing the
'pva size' is similar to what other manufacturers refer to as 'acrylic
gesso'. The two other products I referred to before describe themselves as
'gesso' or 'acrylic gesso' and are intended as sizing for use by artists.
They seem to work for gum sizing - does anyone know if they are actually
basically the same as the Gamlin size? If there are differences do we know
what they are? Has anyone compared these products and is one clearly
superior?

Incidentally Gamblin is not a product easily available where I live, hence
one of the reasons for the interest in its make up.
