Calcium Oxalate: A Surface Treatment for Limestone
Abstract This paper looks at the artificially induced surface conversion of calcium carbonate to the more durable calcium oxalate. Extensive research is being carried out on wall paintings and marble sculpture at the Opicificio delle Pietre Dure e Laboratori di Restauro in Florence, Encouraged by their work, I have researched the effectiveness of the conversion on English limestones.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. This makes marble the hardest of the calcium carbonate family of stones.
