Thank you so much for enlightening me and us I suppose. When others talk about "paste" it looks like ordinary wallpaper paste a lot of the time! So thank you for showing us the original 1800's wallpaper paste!
When I was in college we used paste like this to make paste paper. The paste had been left out for a week and had mold in it that we had to pick out. It was one of the worst-smelling things ever. The paper turned out very nice (and not smelly) and I still have some 20 years later.
Hello, thanks for the video! May I know the difference between different kinds of paste? I've been looking everywhere for answers...like what's the difference in like the flexibility or achiveability between flour/potato starch/tapioca/rice flour paste etc? Also, I've tried using microwave for making paste and it seem to work well, what's your thought on that?
You're welcome. Basically, mixing it with PVA means that the PVA takes longer to dry and therefore gives one more time to manipulate it. I usually use about half half when I do that, but I suppose that it could vary.
Paper warping is caused by moisture rather than the adhesive type. If paste alone is too wet for the kind of paper you’re working with, you can mix paste with PVA (or similar) or use PVA on its own. Only difficulty with pure PVA glue is that it dries so quickly that it’s nearly impossible to pull up and redo something if you get it wrong the first time.
Paste is a traditional and widely used adhesive in bookbinding so it’s been demonstrated to hold quite well lol. Wheat flour paste does yellow over time so it’s not recommended for paper repair (wheat _starch_ paste is better because it doesn’t colour). Wheat flour paste is great for actual binding tasks like attaching cover material to board. Don’t use it where you need flexible glue though, like the spine of the text block. PVA or similar is better.
