Eh i dont know, i guess if you showed that you were indeed interested in glass blowing as an art and not just pipes they shouldnt say anything if you make a pipe or three. In high school when i had ceramics class, i did good enough at all the projects and curriculum that the guy didnt really give a fuck what i made in my spare time, its not like the principal was gonna open the kiln and dive in haha. I made a very nice ceramic glazed stone pipe as well as a quite colorful sherlock and never got any shit for it because i was good at the other stuff as well. i think the same would apply for glassblowing.
