Rosenthal studio-line “Blockglass”: small, sculpture-like trinkets Awarded with the design prize “Design Plus” the collection “Blockglass” is elegant and innovative. Extensive grinding and engraving methods shape the state-of-the-art vases. Similar to sculptures, the blocks are cut, ground and polished until they are perfect in form. Silk-like, soft, organic interiors are covered in crystal clear, strict, geometrical forms. This interplay of contrasting shapes gives the vases their compelling look and they appear like small design objects. “Blockglass” is an extraordinary gift collection. Available in the collection are vases in different sizes, ashtrays, various dishes, a clock, a table light and candleholders in different sizes.
