To
make dichroic glass like the glass used in the skylight,
thin layers of metallic oxides are placed on the surface
of glass in a high-temperature vacuum. Using different
kinds and amounts of oxides (such as titanium, silicon
and magnesium oxides) determines the final color of the
glass.

of the skylight |
Even
though the skylight seems to be made of one large piece
of glass, it's actually made of many smaller pieces fused
together. Getting enough glass for the skylight took a
while, because the company making the glass could only
produce 30 to 40 pieces a month.

Before
you even enter the Science Center, you'll see the world
in a whole new light, thanks to the Dichroic Skylight
in the pavilion outside the main doors. The special glass
in the skylight changes colors throughout the day and
casts beautifully colored patches of light across the
floor of the pavilion.
