In honor of their 20th Anniversary, Glass Alchemy is bringing back select retired colors for a limited time!! Black Pearl is now available.After conducting a workshop on metal lusters and surface work, a student asked why there were no black luster colors. What a brilliant idea. Inspired by this conversation, Glass Alchemy started playing with various formulas that would have the following characteristics: be black, opaque, difficult to muddy, easy to luster, demonstrate non-metallic striking effects! After extensive testing of several formulas, Black Pearl was introduced.Working Tip: Flame or kiln strike at 1075°F. Work neutral; reduce at end for metallic effects.Artist Description by Mike Shelbo:"This color is really nice. The combination of black opaque glass and silver creates beautiful results that can be controlled, to a certain extent. The silver emerging on the surface of the color can be burned off with a hot sharp flame and then reduction can be used to control the amount of silver metallic shine or colored haze desired.
I like working this color without clear encasement, but clear can be added to trap luster and add to design and color possibilities. The color of the luster is mostly greens and blues but can vary depending on application to a range of violets and other colors." - Mike Shelbo
