The graal technique was originally developed at the Orrefors Studio in 1916. Burgundy red was a favourite colour of the studio, and red Graal vases were compared with the chalice of the Holy Grail, leading to the term Graal.

Frank Grenier originally worked with the Master Glassblower, Neil Wilkin, in reviving the graal technique. The initial engraving is carried out on a small egg-shaped embryo, comprising different layers of colour glass. This is slowly re-heated to furnace temperature before a clear glass casing is added. Blowing then commences to create the required size and shape. The engraved image takes on a new appearance as the colours react in different ways to the high temperature: consequently, no two pieces are ever the same.

Frank Grenier has pioneered a unique graal technique by engraving onto the outside surface of the finished graal piece, thereby enhancing the overall affect.
