Can anyone tell me about this hand mirror?
any ideas on this one ? The mirror has alot of sparkles in it. I know it goes back to at least 1900
I wonder ? How old are you?
yes I have heard of putting the lighter up to the mirror but as far as it being true as to the age of it , honey I don't know, I'm claiming it because it's what I've always done, OWCH , change is scary
So, my friend told me that you can tell a mirror's age by holding a lighter close to the mirror, and count how many flames you can see in the reflection. You need to look at it from an angle. Then multiply the number of flames by 7. Does any one know about this? Or ever hear about it? My friend wasn't certain on the number of years and I wanted to know the truth. We tested all of the mirrors in the house, all were different. Any thoughts?
