I think glass scientists and engineers refer to glass as an amorphous solid. According to the Schott Guide to Glass (page 17), 1996, "Glass includes all materials which are structurally similar to a liquid. However, under ambient temperature they react to the impact of force with elastic deformation and therefore have to be considered as solids." I liked the summary of the "debate" at this website: http://www.desy.de/user/projects/Physics/General/Glass/glass.html
I am attaching a brief list of articles and books which address this subject, in case you want to read further.
