Color of the Month: Yellow Ochre Yellow ochre is one of the oldest pigments. The presence of yellow ochre pigment has been identified in the caves of the Paleolithic period of Altamira and Lascaux in France (15,000 BC). Yellow ochre has been widely used in art as one of the main pigments in Byzantium, the Renaissance to these days. The most well-known red ocher are: • French Yellow Ochres • Burgundy Yellow Ochre • Italian Gold Ochre ttps://shop.konstantas.com/category/yellow-ochres #konstantas #konstantasartsciences #pigment #yellowpigment #yellow #handmade #yellowochre #burgundyyellow #hightquality #pure #eggtempera #art #artist #icon #iconpainter #oilcolors #fresco #naturalpigments #science #artscience #artworks #frenchochre https://www.instagram.com/p/CDXNJAwpQUF/?igshid=171k2efhd9g7k

Identification of the red ocher in the icon of A. Ritzos from Benaki museum collection (Icon:22251, 2nd half of 15th c.) by micro-Raman spectroscopy. Cross-section (sample of orange light) in (a) reflected and (b) UV light are shown. (c) Raman spectra of Red Ochre (laser source at 785nm). The complete stratigraphy (a, b) is as follows: (1) gesso ground; (2) red ochre, lead white and grains of carbon black and yellow ochre (3) underlay: organic lake and grains of lead white; (4) light: cinnabar and grains of lead white and yellow ochre; (5) varnish.

Color of the Month: Red Ochre Red ocher is one of the oldest pigments. The presence of red ochre pigment has been identified in the caves of the Paleolithic period of Altamira and Lascaux in France (15,000 BC). Red ocher has been widely used in art as one of the main pigments in Byzantium, the Renaissance to these days. The main component of natural ocher is hematite.The ratio of the concentration of hematite and the granulometry of the pigment determines the color tone and the ability to coat. The most well-known red ocher are: • Venetian Red • Red Pozzuoli • Red Ercolano • Indian Red • Burgundy Red ochre • Novgorod Red https://shop.konstantas.com/category/red-ochres References/Βιβλιογραφία: (1) A.

Macedonian tombs – characterization of pigments in wall paintings. The objective of this work is the characterization of materials, which are contained in wall paintings in three Macedonian tombs: the tomb I of Dion (Sotiriadis), the tomb IV of Dion (Karitsa), and the tomb A (Heuzey). Attention is focused on the identification of pigments which were used in the wall paintings of the three burial monuments. ----------------------------- https://konstantas.com/?p=41 ----------------------------- #konstantas #konstantasartsciences #art #macedoniantomb #investigation #research #pigmentanalysis #pigments #conservation #restoration #artworks https://www.instagram.com/p/CBNv7hUhIb6/?igshid=1nvr9yh8jq5wt

The highest purity handmade Azurite from Russia, gives a unique blue hue. ----------------------------------------------------- https://shop.konstantas.com/product/azurite ----------------------------------------------------- The pigment is prepared by careful selection, grinding, washing, and levigation in controlled environmental conditions by an innovative approach. Coarsely ground azurite gives a deep blue color while finely ground particles give a lighter more transparent tone. ----------------------------------------------------- Χειροποίητος Αζουρίτης υψηλής καθαρότητας από την Ρωσία, διακρίνεται για την εξαιρετική απόδοση φυσικής μπλε απόχρωσης. Η χρωστική υποβάλλεται σε χειροποίητη επεξεργασία και διαδικασία καθαρισμού, πλυσίματος και στεγνώματος σε ελεγχόμενες περιβαλλοντικές συνθήκες, με πρωτότυπη μέθοδο. Παρουσιάζει διάφορες κοκκομετρίες. Η χονδρόκκοκη χρωστική διακρίνεται για τη σκούρη απόδοση χρώματος, ενώ η λεπτή κοκκομετρία αποδίδει ανοιχτό - διαπερατό χρώμα. Η χρήση του αζουρίτη ξεκίνησε από την αρχαία Αίγυπτο. Παράγεται τεχνητά από τον 17ο αιώνα ενώ αντικαταστάθηκε από την χρωστική μπλε της Πρωσίας όταν αυτή ανακαλύφθηκε τον 18ο αιώνα. Ο Αζουρίτης ήταν η πιο σημαντική μπλε χρωστική ουσία στην ευρωπαϊκή ζωγραφική κατά το Μεσαίωνα και την Αναγέννηση.
