Re: polivinyl alcohol vs. gelatin sizing

Thanks Jack,
I went a little bit further than you on my tests and because the glue is a
mess (as you know) I measure it by weight and combine with water knowing
that 1 cc of water is 1 gr. and then move on to further precise ratios and
this means a lot.
I hope this silly trick may be useful to you for future purposes.
Could you detail me your acrilic sizing method? Type of acrilic? household
acrilic? ratios? tricks? and so on.
Thanks
Giovanni
