Instructions
Examine the bottom of the glassware. If the bottom is smooth and shiny, it is not Candlewick. Imperials' glassware, especially the earlier pieces, had rough and rather dull bottoms.
Look at the glassware in light. If there is a bluish or grayish tint to the glassware, it is most likely Candlewick. It took Imperial several decades to perfect the clear crystal technique, so most Candlewick pieces have either a blue or gray tint. There are later pieces that are clear, but the tinted versions by far outnumber the clear ones.
Take a careful look at the balls around the outer edge. Imperial Candlewick's balls are perfectly round, smooth and do not touch each other. The balls are seamless.
Remember that the original Candlewick was only made in clear crystal (blue/gray tint aside). If it is colored glass, it is not original Imperial Candlewick. It could very well be Imperial, but not Candlewick.
