MORE INFO
The pink Aurora marble from Portugal by bildhau can vary greatly in colour depending on the block and origin. The colour spectrum of this interesting sculptor's stone ranges from cream to light pink to very bold pink. Some stones have hardly any veins, others have clearly pronounced dark grey veins, some have red veins and clouds and some have grey quartz inclusions.

PROCESSING
Rosa Aurora marble can be worked very well by hand using forged steel chisels (point chisels, claw chisels, flat chisels, etc.) with a mallet head in combination with an iron hammer. If the marble contains quartz components (grey shading), it can be significantly harder and the use of carbide chisels is recommended. Marble can also be polished by hand to a high gloss finish. In Italian sculpture workshops, marble is mainly worked with compressed air tools, which can be used to shape it very precisely. Polishing can also be done by machine.
Sculptures made of pink Aurora marble are suitable for indoor installation. For outdoor installation, the stone may need to be treated with an impregnation.
FURTHER INFORMATION
Rosa Portogallo is a very old rock, around 450 million years old. The pink colouration was created by iron oxide deposits in the form of microscopic hematite flakes between the calcite crystals of the original limestone, which became marble through metamorphosis over millions of years under the influence of pressure and heat. Depending on the concentration and distribution of the hematite in the stone, red veins and clouds form. (Dark) grey veins consist of graphite, greenish veins of serpentine.
Stone is a natural product. We endeavour to reproduce the appearance of our sculptured stones as accurately as possible in the illustrations so that the character of the stone can be recognised. Ultimately, each stone is a unique piece and the appearance may differ accordingly from the illustration.
