These Bulbs Are Made For Breaking

Have you ever wondered what makes a fire sprinkler start to sprinkle? The answer, in most cases, is a glass bulb. Day-Impex, one of the leading manufacturers of these bulbs, uses Schott Durobax glass tubing to make these precision products. A chemical liquid, sealed in the glass bulb, expands rapidly when exposed to rising temperatures, bursting the bulb at an accurately pre-determined temperature to actuate the sprinkler.
