Owing to abundant resources of quartz and wood in the forests surrounding The Karkonosze Mountains Szklarska Poręba has been known for many centuries for crystal glass manufacturing. First glass factory was opened in Szklarska Poręba Dolna [Lower Szklarska Poręba] at Szklarski Potok[Szklarski Creek] in the middle of 14th century.
Today the many centuries lasting tradition of glass manufacturing is preserved by Mr Henryk Łubkowski, who turned Leśna Huta into family business. Visitors coming there can watch coloured glass being hand made in front of their eyes. The factory manufactures diversified glass forms and ornaments, like flower vases or table glassware.
