I am doing a report for 3 grade and I can not find any information on where quartz conglomerate is found and how it is used. There is a lot about conglomerate but really nothing about quartz conglomerat specifically which is the rock I was assigned. Thank you for any help,.
A quartz heater is a quartz tube with a heating element inside it. The tube glows bright red hot. A ceramic heater is a ceramic structure that holds a heating element, the element itself being exposed. The efficiency is 100% in both cases, in the sense that all electrical energy is converted to heat. This is about the only time the laws of thermodynamics work in one's favor! The ratio of convected heat to radiated heat is slightly higher for the ceramic heater, but not much. For this reason, quartz is favored for overhead heaters.
Just in addition to Dave D's answer, the quartz heater can get up to full working temperature more rapidly, as it doesn't have the mass of the ceramic former to heat, just the relatively thin tube.
