Skills and Compuer Science
One of the tasks you must do as a glass blower are complicated and sometimes dangerous such as:
Heating the glass in order for it to become more easier to control and bend into the shapes you need
Sculpting your glass into shapes to get the desired affect as well as making sure it doesn't run out.
Lastly is blowing which the job gets it's name by using a specilized piper you blow ait into the glass in order for it to widen or to narrow down. It also helps set up the foundation of how the rest of the glass will be built especially it's fraility.
Weirdly enough Glassblowers actually use computer science to build their websites in order to sell their pieces here's are a few examples.
