The Bubbled Vases are made in a small art glass factory located in the south-eastern point of Poland. The artisans first form the blue glass in a mold. Using a round tool, the interior bubbles in the abstract shape are pushed out of the wall of the vase creating a soft blue color tone. Lastly, the glass is annealed for over 24hrs to cool. Each piece is unique, so shape and color may vary.
