Ah, thank you! I haven't even considered that someone could be using the "at symbol"...
There's definitely an M. Tampol out there. Or "M. Tam Pol".
Still can't find any additional information, i.e. is this a designer that works for a glass house, or an independent artist, etc.
Weird that someone making glass art wouldn't have any searchable or social-media presence... oh well. #shrug
