As you can probably imagine, if you were a glass technician, you would spend a lot of time working with glass. You would help install glass, repair glass, sell glass, clean up broken glass, and in general, do anything that needs to be done with glass.
You could be a flat glass technician or someone who works mostly with windows and doors in homes or businesses. Or you could be an auto glass technician, someone who works with glass windshields and windows in cars. For both kinds of glass technician jobs, you would need to be an expert in repairs using tools such as resin, weatherproofing treatments, and more.
You probably wouldn't need a bachelor's degree to be a glass technician, as this is the kind of position where you learn the important skills on the job. Some employers may want you to have a certificate from the National Glass Association. You may also need a driver's license so you can drive the company vehicle to customers having glass emergencies.
