You asked about b-72 Acryloid and Hxtal. According to our Conservation department: "
Both B-72 and Hxtal can be excellent fill materials, but they have different applications. It all depends on the type of glass and object that needs to be filled. One is really not better than the other except in the treatment of a specific object. If you want to compare them you will need to have fairly narrow parameters.
Both can be colored with dry pigments or dyes."
You can see some publications on their department home page : http://www.cmog.org/conservation-research-and-publications
These are items you can likely obtain (if not online) through your local library's interlibrary loan department. We make copies and loan books for free to other libraries.
Please let me know if you'd like more information, after looking at these resources. I am also copying some references from a bibliography on adhesives below.
