Restoration and Conservation of Delicate Materials With Mold

Introduction

The problem is: how to conserve and restore delicate materials such as leather or vellum books, paper books, documents, archival records, art works and textiles after water damage once they have mold without damaging the object. Most of the commonly used mold treatments such as regular heat sterilization, methyl bromide, ethylene oxide and ozone bleaching can damage or destroy the delicate structure of a leather or vellum books, paper books, documents, archival records, art works or textile being treated while they are killing the mold or bacteria. This risk to the materials, not to mention damage to the environment, are now of critical importance. The solution is a two step process: vacuum freeze drying and plasma fumigation.

Most water-damaged materials will show signs of mold growth after a short time. Initially, water damaged documents and books have to be blast frozen to minimize large ice blocks which can further damage leather or vellum books, paper books, documents, archival records, art works and textiles. Next, normal freeze drying is used to remove the moisture from water damaged materials. Unfortunately, normal freeze drying has its drawbacks. Freeze drying removes the water, but not the mold and/or bacteria. Continue reading »
