Blown glass vase of yellow and crimson glowing embers.
Depicted in the vase wall are the hot coals used by ancient glassblowers to generate the intense heat required in glass making.
Ancient furnaces used bellows pumps to force oxygen into a coal bed to enhance combustion and intensify heat.
The oldest known bellows were in China 7,000 years ago which evolved into waterwheel driven air pumps of sewn animal skins.
Modern glass furnaces use combustible gas instead of coal but we still use air pumps to intensify heat.
