I am trying to identify a wavy iridescent glass vase that was given to me. I was told it is very old over one hundred years. The markings on the bottom of the vase are a series of small circles that make up one larger circle. Then within the large circle are more smaller circle ending with one circle in the middle. I would like to find the manufacturer of this vase and its history. Can anyone help me achieve this, I would appreciate all the help I can get.
