 * USE OF 2-PROPANOL IN THE RESTORATION OF FRESCOES.** **Hannah Ross and Sophia Ganapes.** This lab is an attempt to determine the effectiveness of 2-propanol alcohol in the restoration of frescoes. It has been previously found that a mixture of calcium hydroxide and 1-propanol has worked, which leads to the question of if all isopropyl alcohols would be effective. 2-propanol was chosen for its availability. The three types of damage were physical, water damage and acid rain, each of which was simulated in lab. By testing a mixture of 2-propanol and calcium hydroxide at the same proportions of the effective solution on a variety of damaged frescoes, .25 g of Ca(OH)2 to every 40 mL of 2-propanol, the similarities and differences of the alcohols in respect to restoration of frescoes is explored. The data was inconclusive for water damage and acid rain damage because the frescoes did not appear damaged.
