The invention involves fabricating a ceramic tube, e.g., a silica overcladding tube (10), with very little bow, e.g., about 0.3 mm per meter or less. In particular, the invention involves securing the tube (10) by a handle (22, 40) that both allows the tube to hang plumb during treatment, and also is capable of deforming during such heat treatment to maintain the plumb arrangement. <IMAGE> |
