Chandelier candle holders

The use of Coldur-A® for chandelier candle holders at a world famous theatre is one of the more creative applications for this versatile alloy. The Sam Wanamaker Playhouse, the candlelit indoor theatre at Shakespeare’s Globe in London, approached Columbia Metals when searching for a suitable material for exactly this purpose.

Coldur-A® silicon bronze forges well, has a lovely colour and tarnishes down very nicely,” explains Penny Spedding, the heritage metalsmith commissioned to create the props for the Sam Wanamaker Playhouse. “The indoor candlelit theatre is the first of its kind and the alloy reflects the candles when it’s polished, creating even more light in the theatre.”

Coldur-A® sheet was selected for the forged cups and candle holders in a set of seven chandeliers.  The alloy was also used in candle sconces after being hand beaten and formed and subsequently silver soldered.

Penny is regularly commissioned for props, sculptures and furniture for theatres across the UK and has extensive experience in working with a range of metal alloys. “Columbia Metals has very helpful, informative and friendly staff,” she concludes.
