The town of Razgrad is situated in North-East Bulgaria, on a railway line connecting Varna and Rousse. The region is well known with the big fields of high quality kaolin and quartz sand, which are the basic raw materials for the production of glass and porcelain. The big reserves of local raw materials are a basis for the creation in 1935 of a small factory for chinaware in Razgrad. The plant is situated on an area of 413 910 sq. m. Diamond Co. has been producing glass since 1961. At the beginning the production of sheet glass has been by the method "Furko" and since 1975 by the method "Pitsburg". The company works exclusively with Bulgarian resources and disposes of excellent experts.

Today Diamond Co. is the biggest enterprise in Bulgaria in the field of silicate industry. Diamond Co. produces: sheet glass by the "Pitsburg" method; wired and figured glass - coloured and colourless; light reflective glass; mirrors; safety (triplex) glass; insulating glass; water soluble glass (solid) - modules 2.2, 2.8, 3.3. The company produces household porcelain with European design and decoration, too.

Diamond Co. releases complete service of the glass and porcelain expeditions - sea transport charting, container and automobile transport, insurance of the goods, etc.

Diamond Co. has stable position on the market in Greece, Italy, Turkey, Macedonia, Tunisia, Morocco and carries out orders for the countries from the Near East and Central Africa.

Hereby we invite all the interested to release a co-operation of mutual interest in the sphere of glass and porcelain production and consumption.
