That's what I meant. > What quality and strength is appropriate for most piano work? Or is >there one strength/quality for each task? For most piano work any hot animal glue is stronger than it needs to be by a huge margin, so I use the glue that is most flexible, most convenient to use and (for hammers etc.) most good-looking. I do have pure hide glue in grain form and of very high strength that I will use for critical construction jobs, and I also have "rabbit-skin glue" which is either what it is called or which is rather a good quality glue made only from hides, not necessarily rabbit-skins. Both of these have a more cloudy appearance when set and have other distinguishing characteristics that I won't go into now. I don't use these glues for most work, ie. action work, because they are far tougher than they need to be and less convenient to use, gelling too quickly, requiring a narrower temperature range etc. The term "hide glue" is used a lot on this list, and perhaps in America generally, as a synonym for hot animal glue in general. In England we tend to talk of "animal glue" or even "Scotch glue". There are many animal products suitable for making glue and I think most commercial pearl glue is made not only of hides but also of bone and probably also of some fish gelatin. When I was a child you could go to any hardware store and buy a dark slab of Scotch glue that was probably made of hooves and was certainly not of good quality, but I'm sure it would have done most piano work quite adequately if prepared and used properly.
