Abstract
The electromagnetic calorimeter of the CMS experiment is now entering the c onstruction phase. Consequently the crystal production will soon start. The preproduction phase which started in august 1998, is foreseen to allow for further optimisation of the final crystal production scheme. A general ove rview about the quality and characteristics of the first large batch of the preproduction crystals will be given and the results will be discussed wit h respect to the final production requirements needed for high resolution c alorimetry for CMS.
