History of Kostopil glass plant starts from the beginning of XX century. In the middle of 1913 a Polish squire created the glass guta which was manufacturing the large bottles of different capacity and the glass bulbs for kerosene lamps.
After the Second World War in 1946 the glass plant started its work again manufacturing the same items.
In 1962 the plant was functioning under Lviv Radnargosp authority (central administrative board of electronic industry). Right at that time the building of workshop №2 had been started with two glass melting furnaces which produced glass insulators and bulbs for vacuum electronic lamps. In 1972 manufacturing of glass and pyrocerams had been started in the workshop №3. With development of science industries there was a requirement in new kinds of products and that is why the workshop №4 was built to manufacture the glass linings for the integral circuits. To achieve that purpose the workshop manufacturing glass composition materials was bought from the USA.
Peak of the Company growth was reached inthe 80s, when the Company had been producing unique items for radio electronic inductry as well as for food products, At that time about 3,3 thousand people were employed in the Company.
