Smithsonian conservators and scientists analyzed the ruby slippers, identifying more than fifteen component materials. Then they determined if any were releasing gases that could damage the shoes if allowed to accumulate in a closed display case. Next, they developed specifications for a case that provides active air exchange with stable temperature and humidity, and lighting that heightens the shoes' colors and minimizes light damage. Finally, they cleaned the shoes, stabilized loose parts, and meticulously realigned the sequins. |
