A natural field-mixed glue used to glue together upright cemetery headstones. Casein glue can also be used to glue small pieces of brick and stone masonry together. It has a respectable strength using calcium caseinate to significantly hold together units but will still remain reversible. Used in conservation work, if a tablet stone were to be pushed over, Casein glue will allow the stone to break at the glue point if enough force came upon to seam and not encourage a new break at another location if vandalism were to occur. The product comes in two parts; Casein/Lithomex powder and Ecologic™ Waterglass as the liquid additive.
