List, I've done some study on the different types of hide glue, (and there are many!), "pearl" glue is a substandard variety IMO. The best I have found is 3XChrome, which I buy in large quantities. I sell it to my chapter members and those who need the really "good" stuff. To give you examples of the many types, there are ground glues of many different grades. There are flake glues which are usually better grade. There are Sheet glues which are in the substandard class, along with pearls. All of those basic categories have many different grades and this is just the tip of the iceberg, so to speak. Regards, Joe Garrett, RPT
