Hi everyone
Initially I had thought this had a Victorian look about it, but I discounted this and now think it's much more modern. I've put possibly Japanese in the subject header because this kind of red going into orange colour is something I associate with Japanese glass, especially when combined with clear. However I've not seen this style of optic glass from there.
Two distinctive things that might help towards an ID are firstly the rim is slightly pinched. It's not pronounced enough to call it a spout, but seems deliberate enough to be intended as a pouring vessel of some sort...? Secondly there is a flower design impressed on the base.
I'll post the photos separately as I'm having difficulties uploading.
Thanks Geraint.
