Satin Frost or Acid Dipped Glass was done by Viking way back in the 40’s. I am not a big historian but I know it goes back a long ways. I have made no excuses for my lack of knowledge as to the way Art Glass is made. I just love to look at it and collect it.
Many of the Viking Glass Epic Birds produced in the late 70's and early 80's were dipped to give them the Satin Frost look. It is not that hard of process. As a matter of “FACT” it is very simple! It is so simple people are doing it and selling them as Rare Pieces.
