Left image: Crystal as supplied in chunks, Right image: Crystal after casting

Deep red when cast, very dark when used full strength in thick pieces.  We often mix with clear.  Can appear 'brownish' when cast in thinner pieces.
Colour shift (strike) happens when fired. A reliable "striking" colour

Transparent Quality
With 35% lead content, Blackwood Casting Crystal provides a true transparent quality to cast glass works.

35% lead content gives you a high volume to weight ratio (12% more volume than other lead casting glasses).
Wax formula - wax weight x 3.51 = blackwood casting crystal weight

Precise measurement
Blackwood Casting Crystal is supplied as un-annealed chunks.
The chunks are very easy to break, allowing for exact measurement of glass quantities.

Kathryn of Auckland says:-
"One of the standout features of Blackwood Crystal is the level of transparency I've been able to achieve, which is something I wouldn't normally associate with cast glass. It's also easy to break up for measurement, and responds extremely well to cold working."
