3 CONCLUSION

BECAUSE A LOW resin-to-microsphere volume concentration is sufficient to form a cohesive fill, this material was found to be easily reversible with a minimal amount of an appropriate solvent. Ghosting problems associated with plaster or other fillers commonly used on porous materials are avoided, as are potential problems for water sensitive gesso, wood and painted surfaces. This fill material also produced promising results for the filling of marbles and faience.
