Unveiling the Materiality of 19th Century's Color Spaces

Color Research &Application, EarlyView.
ABSTRACT Several color theories flourished during the 19th century, marked by experiments on the distinction between color‐light and color‐matter. This study aims to compare the color plates designed to illustrate three of these color theories, namely M.E. Chevreul's chromatic circle (1861), O. Rood's frontispiece (1879), and C.

Investigating the Degradation of Historical Man‐Made Cellulose‐Derived Textiles via Accelerated Ageing

ChemPlusChem, EarlyView.
Cellulose‐derived materials, such as paper and cellulose acetate, degrade in museum collections. The degradation of man‐made cellulose fibers remains poorly understood. This study examines historical cellulose acetate and regenerated cellulose textiles using accelerated ageing. Identified markers, for instance surface changes, mass loss, discoloration,

COLORS FROM THE PAST: ION BEAM ANALYSES ON GLASS FINDS EXCAVATED AT THE LATE IRON AGE SETTLEMENT FROM TINOSU, PRAHOVA COUNTY, ROMANIA

ChemPlusChem, Accepted Article.
This paper discusses the results of Ion Beam Analyses (IBA) on 20 glass items excavated at the Late Iron Age site from Tinosu, Prahova County, Romania, broadly dated to the 2nd c. BC – 2nd c. AD. Most glass fragments originate from naturally colored or intentionally colored tableware, which were either monochrome (green or blue) or polychrome (mosaic ...
