The Block Optic pattern was made by Anchor Hocking from 1929 to 1933. There is some confusion as to the function of this particular item, as some old glassware books refer to this as a covered candy and Replacements calls it a sugar bowl and lid. I have also seen others call it a powder jar, but it is really not the right shape or size for that. Apparently the satin finish or frosted look was only done to a few items, in the green color. It reacts nicely to the black light and could be used to hold so many things in your vanity area or on the desk.
This two piece footed sugar is 4 3/4" high with it's lid in place. Both pieces are free of any chips or cracks, although you can feel a couple of rough places around the edge of the lid. Looking inside, there is a white residue that you can see in the 3rd picture. The hand painted decoration is still visible, although it is starting to wear off.
