Glazing over: A review of glazing options for works of art on paper

Summary This paper summarizes the advantages and disadvantages of glazing options, focusing on glazing for works on paper. In light of continuous improvements being made to the physical and optical properties of glass and plastics, combined with improved museum practice and safer art transport, new products have been introduced, and the suitability of glass as a glazing option is re-assessed. In relation to this, the author looks at the results of tests carried out on glazing at Tate, in which glass is found to be extremely resistant to breakage. Questions are raised about the validity of always taping the glass, and regarding assumptions about the safety of acrylic. It is found that mount types and spacers in frames affect the breakage threshold of the glazing and the type of breakage sustained. Summarizing current glazing procedures at Tate (including the use of both glass and acrylic), the author emphasizes the fact that the performance and safety of any glazing is only as good as the quality of the framing, packing, handling and transportation to which the glazed work is subjected.
