This is a pair of Bohemian Czech art glass candlesticks, or candle holders. The maker is Kralik. The date is circa 1930.
The bottom of one holder is signed Czechoslovakia. The name is there, but it was difficult to photograph. If you use an app on your smart phone that has a magnifier with a flashlight, you will be able to see the name clearly. I put a piece of tape next to the word.
There are three layers of glass. The middle layer is splashed (spatter), with streaks of orange, brown and yellow. The inner layer is white. The outer layer is clear.
The candlesticks are 8 ¼” high and 4” wide at the base.
There are no chips, nicks or cracks.
