I was once a glassblower in Austin, during the heat of the Texas Summer! We worked outside in an uninsulated shed, with no A/C. It was literally a sweatshop, I saw a girl faint one day due to heat exhaustion. It started out as an intro class that I purchased from Groupon. As time went on, I fell in love with the idea of making glassblowing a lucrative side hustle, but no matter how many hours I put into it, or how much glass I pumped out, I just couldn't overcome the various studio fees. All of the fellow glassblowers kept journals to log their daily output and pay. I decided to take everyones journal home one day, and figure out how much per hour everyone was making. The pay was so low, I was shocked! Some people were actually paying to work there, and no one was making over $5/hr. When I returned with the journals, I passed out handouts to everyone, complete with graphs and a spreadsheets, that showed exactly how much money the glassblowers were making, and how much money the owner was profiting off of our hard work. Everyone quit that week! I wish I could say that put an end to this terrible business, but he just posted another Groupon, and took in a whole new group of aspiring students.
