After more than ten years of intensive research, the first encyclopedia of GLASS MARKS from the 16th to the 20th century is now available; there has been no comparable publication until now! The starting point is the mark you are looking for. The encyclopedia is clearly arranged and easy to handle. Right next to the mark you will find all necessary information. The 'mystery' of the mark is solved and you will find sound information on the artists/manufacturers/or the producing glass factories, as well as when the works were produced. In addition you will find thousands of biographies of artists in glass and firms from Europe and North America.
In German (user instructions also in English, French and Japanese).
