Kaj Franck 'Harso' Vase

An early, museum quality example of a 'Harso' vase designed by Kaj Franck, Finland, 1953.

The shape of the vase is free-blown whilst the decorative pattern within has been achieved using the ariel technique.

Essentially, a wave pattern has been acid etched around the glass at the core of the piece. Overlaying the translucent off-white core is clear glass which has trapped air bubbles in the recesses of the etching beneath. 

Nuutajärvi Glassworks produced this design, with the Model Number KF108, for 6 years, from 1953 to 58.
