Hxtal NYL-1, an epoxy, and Loctite 350, an acrylic adhesive, have been evaluated for use in the conservation of glass, particularly the Portland Vase at the British Museum. The results of accelerated aging of the adhesives using light and heating aging regimes are reported. Hxtal NYL-1 was found to have good color stability to light aging but poor stability to heat aging. It is reversible using solvents. The color stability of pigmented samples of Hxtal resin was also investigated. Preparation of pigmented resin was found to be difficult, and the colors investigated exhibited some fading during light aging. Loctite 350 was found to yellow slightly during both light and heat aging and to be reversible using solvents followed by mechanical removal.
