This part is for the moment
described only in Swedish language.
Historically buildings tell us that the
used stone materials have various qualities. Knowledge about the limitation
of the material, was very early discovered by stonemasons. But the lack
of machinery and resources made it impossible to get enough raw materials
to produce right quality for right purpose.
Due to these fact restorations regularly
has been made on buildings where wrong, for the purpose, quality is replaced
by right quality.
With historical understanding and knowledge
of today, plus high technical equipment, ÖLANDSSTEN AB are developing
the tradition of quarrying and producing Ölandstone.
The products are mainly for facing material,
both inside and outside buildings.
To produce right quality the production
follows a quality system for sorting the materia.
has developed a system for sorting limestone from the quarries Horns udde
and Gillberga. With reference to layer in the quarry, one gets information
about the stone materials colour and general quality. The material is sorted
in nine different colours. There is also made a sorting according to the
range of defects that are natural in the material, for example cracks.
The sorting rules
describes what type of defects that are allowed according to the use of
of different colours are:
- Grey G1
Each denomination and
defects that are included in the sorting rules are described in product
sheets. Here are also described the technical data for the material.
- Mixed patterned F
- Grey G2
- Grey G2H
- Grey G2S
