Trani

The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.

Petrography

Finest grain, compact, beige-pink to cream- pink coloured limestone from the south Italian natural stone region Trani-Bari. Characteristic are the wavy to jagged, but largely in parallel running pinkish-brown clay veins, the so-called stylolite. These are partially calcified and can, therefore, be polished, so that the lighting is evenly reflected on the surface. Across to this, run a few transparent or white calcite veins, which are healed shrinking fractures. Fossil inclusions are rarely visible. Occasionally, white, round algae fragments occur. Trani shows numerous clearly distinct banks, due to which variations of colour and structure occur. 

Petrogenesis

During the medieval earth age, lime sludge and clay particles were deposited in parts of the former Mediterranean Sea. These have been solidified by diagenesis over the many million years. Diagenesis takes place essentially by cementation with calcite and can occur already during sedimentation or in different periods afterwards. Lime, dissolved in water, is deposited around the particles and connects these with each other. Cementation can lead to complete freedom from pores and heal setting cracks and small fissures in the form of white to transparent calcite veins. If the mountain range pressure has had an effect on the different components clay and lime during the further petrogenesis of the lime sediment, the clay content in the limestone has been pushed together into thin bands in parallel to the layers.
