Hi Anne
Well.....at first I thought colour changing glass was quite cool
but now... I am beginning to really dislike it
I looked at my lovely lilac vase tonight after you prompted and put near a low energy bulb this is what happens (see last picture).
I now have a fabulously heavy bowl that I can't put anywhere other than the hall because instead of being lime green it turns dirty pink under normal lighting, and a vase that I can't use in the hall because it makes it go a aqua instead of lilac
- Well, I guess that is the answer to your question
I'm going to start taking a torch with me just in case I buy any glass
