Polychromatic Colors
(silver-based formulations)
All silver colors should be worked at hot temperatures to create, form and assemble the elements. Once
your piece is formed switch to a lower heat, just above the annealing temperatures 1075°F to 1125°F,
to grow the silver crystals. The smallest crystals are invisible. As they grow they will create a yellow
color. In order of increasing size, the silver crystals will become orange, ruby red, red-purple,
purple, blue then green.
When working with silver colors, you will want to pay attention to the temperature profile that you are
creating within the glass piece you are working on.
From the scale above, note that the heat penetration is deep.
From the scale above, note that the heat penetration is only on the surface and inconsistent.
From the scale above, note that the heat penetrates the surface and immediate subsurface, but is not deep.
Also note that the heat is consistent.
Once you start recognizing the heat profile, you will have gained another level of color control. For
example, if you let the core temperature drop and then reheat only the surface, the silver crystals will
grow faster in this top layer than the layers just below. If the heat is uneven, you create a “veil” of color
