Swedish Blue Slag Pendant - 1600's Sweden
$78.00
This Swedish Blue Slag pendant is made from historic slag glass produced during iron smelting in Sweden in the 1600s. The vivid blue color formed when silica-rich slag cooled and trapped trace elements from the smelting process, creating glass with flowing patterns and depth.
Originally considered an industrial byproduct, Swedish blue slag is now valued for its connection to early European ironworks and its unmistakable color. Each piece preserves a tangible fragment of industrial history, shaped by heat, chemistry, and human craftsmanship. It makes an incredibly unique and beautiful pendant!
