You're right about the composition, I guess, so that's why we ended up eating it when we were kids. It was a very common adhesive for paper in Italy during the 1950s and 1960s. It was packed earlier in light aluminum containers with the name embossed and then in blue plastic containers, it dried quickly with a fractured texture typical of starch and glycerol. I still have some of my early chef-d'-oeuvre pasted with coccoina and I can tell you that it has no effect on the paper but it loses all adherence and the adhesive became brittle and crystalline, yellowish. PS it's better on toasted rye bread ;-) Pierlucio Pellissier now in Montreal *** Conservation DistList Instance 13:49 Distributed: Thursday, March 30, 2000 Message Id: cdl-13-49-005 ***Received on Saturday, 25 March, 2000
