I kinda thought animal product to animal product---Hide Glue??--ya know, the
stuff they make by boiling hides,hoofs,horns,etc...

I've just checked in Spon. Their recipe uses equal parts of hide glue

They're mixed cold and wet, before heating. Once hot, tannic acid is
added until the mixture turns "ropey, like egg white".
