“In 1955 the Harrachov factory in Bohemia in Czechoslovakia launched a range of art glass called Harrtil. It was developed by designer Milan Metelak and factory manager Milos Pulpitel. The fine white mesh of woven glass fibers (known as "merletto" - net - in Italian) trapped within heavy glass casing can be seen in all the pieces in the series. Harrtil is often mistaken for the merletto pieces of Archimede Seguso, but the mesh on the Seguso works are an illusion created by joining two blown bubbles with filigree lines, thus creating a net-like effect. Harrtil, on the other hand is made with a genuine net of woven glass”.
