+====== Choosing a Crucible ======
 Important information on deposition of different materials (as well as which crucibles to use) is found on the [[https://www.lesker.com/newweb/menu_depositionmaterials.cfm?section=evapac&init=skip|Kurt J. Lesker site]].
+A common reason for crucibles to break: the user shuts the power supply off or has a very short ramp down time for power after the deposition is done. This causes the rapid solidification of the melt, and this stresses out the crucible liner.
