A new collection of vases and items set is a result of work focused on Plexiglas contour lines, which maintain their raw form. The base shape is made from handmade blown glass covered with layers of Plexiglas and sand. The structure of these items is similar to that of rocks found in nature, except their form is not the result of the influence of time but of Vlastimil Šenkýř experiments with the material. Despite their structure being very similar to rocks, they were created by human activity and not by nature. Does this make them artificial though?
