Bullseye Glass: List of Suspended Glass Colors

Bullseye Glass has been at the center of controversy about Portland, OR air pollution ever since early February, when Oregon regulators asked the company to stop using the carcinogenic metals cadmium and arsenic. The request was prompted by tests showing high concentrations of the pollutant in nearby air.

Bullseye Glass and Uroboros glass have agreed to stop using cadmium and arsenic in their manufacturing, along with a third and more toxic metal, chromium. A list of Bullseye  Glass colors affected by the manufacturing change was obtained by Washington Glass School – as follows:

Glass Beads Found In Danish Grave Linked To King Tut’s Death Mask

Scientists working in Denmark have unearthed glass blue beads crafted in an ancient Egyptian workshop for King Tutankhamun that made its way north to Europe 3,400 years ago. The find helps prove there was contact between the two regions long ago and suggests possible ancient trade routes.

After taking a new look at a pair of ancient cobalt beads, archaeologists now believe these Bronze Age artifacts may have been manufactured in the same workshop as the blue glass on King Tut’s death mask. The researchers say the new discovery is the first Egyptian cobalt glass that has been found outside the Mediterranean area.

For the research, an international team of Danish and French archaeologists used a technique called plasma-mass spectrometry to analyze the chemical composition of 23 glass beads dating back to between 1400 and 1100 B.C. The set of beads was unearthed from Danish graves in the late 19th century.

If that’s the case, an extensive trade network likely ran from ancient Denmark to Egypt and Mesopotamia around 3,400 years ago, the researchers say.
