If it isnt copyright there is no proof you made it first people have been making replicas of others glass for a long time now. If yours was first and is a higher wuality people will know and support you. Theres alot of people blowing glass and just because one pwrson had an idea to make something doesnt mean someone else doesnt have the right to make that if they also had that idea its not always someone stealing some else’s art. That defiantly happens and isn’t cool but theres also a-lot of people out there and only so many objects you can create that sometimes people will have the same idea as you. Not trying to say your wrong just that it would t stand up in a court id theres no copyright.
