They deal with crazy pressure shifts and wild temperature swings. If you don&rsquo;t get the internal stress out of that glass during annealing, it’s eventually going to shatter. Simple as that. We don&rsquo;t just sell you a few lamps and wish you luck. We look at your whole thermal profile. The goal is to get the glass to that soak temperature without it warping or twisting.</p>
