Thank you for your reply Christine. I did indeed mean Empoli.
Tigerchips, thank you. I had previously checked the information in this link you have provided. However, I was still confused as the red glass label is different to the one on my vase, as in mine is gold foil and the letters are BT. I did not pay a lot of money for this vase on eBay but I am still interested in whether it is indeed genuine.
Is the red glass label the only one used for red glass? The design of my vase doesn't lend itself to a Chinese fake style in my opinion, but of course I am no expert so could easily be wrong.
