This is a WILLOW OAK Crystal Tumbler that has been stuck up and iridized by Terry Crider. This is an EAPG pattern, also known as Oak Leaf/Stippled Star/Acorn/Thistle, that was made by US Glass in 1891.
This WILLOW OAK Tumbler is iridized PASTEL MARIGOLD; it is a Ginger Ale color with subtle iridescent colors, pastels. This is a very, very nicely colored item. This one is Signed Crider on the base.
Crider would pick up items, take them to his shop, where he used metallic salts that he made and then iridize the item. Any Crider EAPG item is very scarce and some are one of one. The contemporary items were purchased as non-iridized blanks at the factories, so, there will be more of that type item, but, still very limited.
Circa: Tumbler 1891; Crider iridized 1976-90.
3 3/4 inches high.
3 inch top.
2 3/8 inch Dome base.
