How to date Orrefors - signatures, series and date codes.

Dating Orrefors Glass

Orrefors used different signature systems for different types of glass. In the following pages we have tried to give as much information on the different types of signatures and dating systems as possible. Orrefors used different numbering systems with most of their art glass. The numbers work like serial numbers or date codes: from the number or number and letter combination, you can see exactly in which year the piece was made by Orrefors.  

For each technique used by Orrefors, there is a link to a special page where you can find all the known date codes and serial numbers that were used at Orrefors. Just click the links in the text to get to the correct page. 

In no way does the list below claim to be complete and 100% correct, but it should help to give you a good indication about the age of your glass.  As we learn more about the different dating and signing systems in use, we will add these to our website.

Orrefors Graal

The Orrefors Graal Glass went through several stages of development to get to the Graal technique that we are used to today. Basically, the first Graal pieces were developed at Orrefors in 1916, and the same technique was used until 1936. At the beginning of the 1930s, Edvard Hald and Vicke Lindstrand experimented with the Graal technique and came up with the "new" Graal method, which basically meant that the layer of clear glass that is applied is thicker. There are several numbering / codes systems that were used.

Orrefors Slip Graal (or Slipgraal)

The Slip Graal technique was developed in the late 1930s. In 1940, the technique got its own numbering system. Edvard Hald developed this technique further with Heinz Richter to form the Aquagraal technique. These vases did not have their own numbering system, but were included in the Orrefors Slipgraal serial number / date code system. Early Slip Graal pieces have the letter "S" in front of their serial / date code. From 1953 onward this letter was omitted, since the pieces were clearly marked Slipgraal anyway.

Orrefors Ariel

Almost all well-known artists / designers at Orrefors worked in the Ariel technique. The most famous pieces by Edvin Ohrstrom, Ingeborg Lundin, Vicke Lindstrand, Olle Alberius, and Lars Hellsten are Ariel pieces. All Ariel pieces are signed with the artists name and a serial number / date code which allows to exactly date the piece. Early pieces had the production date mentioned seperately on them.

Orrefors Kraka

Sven Palmqvist inveted the Kraka technique in 1944. Early Kraka pieces were mostly of a single color, white being the most prevalent. Orrefors produced Kraka glass pieces until 1986. From 1960 until 1986 several models were mass-produced. Palmqvist himself produced Kraka pieces until 1972. We have all the date codes and serial numbers that enable you to date your Orrefors Kraka piece.

Orrefors Ravenna

Apart from the Kraka technique, Sven Palmqvist also invented the Ravenna technique for Orrefors. He produced Ravenna pieces himself until 1981, but Orrefors continued to mass-produce certain Ravenna models until 1989. We have collected all the date codes, serial and model numbers that enable you to date your Orrefors Ravenna piece.
