Circle Carafe Glass by Milena Kling Dimensions: 8 x H 20 cm. Materials: Mouth-blown crystal glass. Each Circle is individually mouth-blown in finest crystal glass and hand-polished by artisan craftsmen in the heart of Bohemia. The Circle glasses are produced by Lasvit and designed by Milena Kling. The fine collection of mouth-blown table glasses is composed of individual silhouettes, handcrafted by traditional artisan glassmakers. The delicate linear engravings on the Circle glasses result from the original production process using fine, pleated copper sheets. The flexible copper mould allowed the fluid glass to take on its free-flowing circular forms.
