Clari-crystalline was an expensive substance that the wealthy often used in place of Transparisteel as glazing for windows. While it offered a clearer view, a sharp tap could shatter it to a thousand pieces.
One known manufacturer of clari-crystalline was Congressional Crystalline, a company based in the Senate District on Coruscant. It was commissioned by Senator Padmé Amidala to repair her bedroom window after Obi-Wan Kenobi shattered the window in pursuit of ASN-121.
