The development of a ready-for-use poultice for local removal of starch paste by enzymatic action

An enzyme poultice for local removing brittle and hardened starch locally w ith a minimum of moisture has been developed. The recipe for the gel contai ning enzyme and the way of application aims at reproducible results to be o btained in a short time. The enzyme poultice is available ready for use and can be activated by adding water. It enables the dismounting of large batc hes of mounted sheets without further treatment. It is essential to use the poultice in the way described together with an interleaf paper. Contaminat ion of originals due to the treatment can be minimized in this way.
