Double wide rectangular shaped solid cast candlestick holder. We found some graphite molds that our studio used in the 80s and decided to give them a whirl. This style of candlestick was popular in a lot of mid-century European glass studios from Denmark to Sweden, Italy and the Czech Republic.
These candle holders are hand cast, and you should not let the flame burn down into the candle holder. A direct flame on glass can cause breakage. Snuff your flame when it reaches 2cm above the glass.
Most are clear but one short candle holder has threads of tranparent green throughout the piece.
