<strong>MCI</strong> 6219 Gemini 8 Thruster Resin<br />
<strong>MCI</strong> Staff: Jia-sun Tsang, Judy Watson, R. Jeff Speakman<br />
The cast resin was analyzed to determine if it contained sulfur compounds or<br />
other compounds harmful to the artifact materials. The results were used to evaluate<br />
whether the cast resin should be removed from the artifact.<br />
The artifact, a nozzle section from Gemini 8, is considered a piece of space<br />
history. In the 1970s, it was mounted in a Lucite-like resin as a paperweight. Silver<br />
items set in similar Lucite-like resins were found to be darkening. While Lucite is not<br />
reported to contain sulfur, information from manufacturers indicates that some formulations may<br />
contain sulfur. Removal of the object from the resin may be desirable if the resin is found to<br />
contain destabilizing ingredients.<br />
