Has anyone ever used a product called "Museum Wax"? It's a microcrystalline wax that's suppose to be safe for securing pottery, glass, wood, etc., but I'm hesitant to stick this stuff on artifacts. I received some of their literature in the mail, and I could use something like this if it's safe. It's produced by a company in California called Trevco that makes earthquake-proofing devices. They also make a picture frame hook that keeps the framed item from jumping (or being easily lifted) from the wall. I've been looking for a hook that's more secure than the kind you'd buy at the hardware store, and perhaps someone can recommend one that works well. Thanks!
