Quantitative analysis of texture of ground paints in paint cross-sections

چکیده
Rincewind was in his new office, filing rocks. He'd worked out quite a good system, based on size, shape, colour and twenty-seven other qualities including whether or not he felt that it was a friendly sort of rock.

Micro X-ray diffraction for painting and pigment analysis
Micro-X-ray diffraction (Micro-XRD) offers many opportunities for non-destructive, in situ crystalline phase composition analysis of varied artworks. This paper discusses the application of this technique to paintings. Painting surfaces and cross-sections can be examined to characterise pigments and provide additional information complementary to existing investigative analyses, which often rel...
متن کاملOptical Characterization and Modeling of Black Pigments Used in Thickness Sensitive Solar Selective Absorbing Paints
The performance of black pigments used in thickness sensitive solar selective absorbing paints for solar thermal collectors depend on the optical properties of the pigments. Knowledge of the intrinsic optical properties of most paint pigments is very limited. Pellets made from either FeMnCuOx or black carbon dispersed in KBr matrix have been used to determine the effective optical coefficient...
متن کاملElectrochemical Characterizations of Epoxy Coatings Embedded by Modified Calcium Carbonate Particles
In this paper, electrochemical behavior of epoxy paints embedded by modified calcium carbonate particles was investigated during exposure to 3.5 wt% NaCl solution. The precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) particles were utilized as inexpensive filler for epoxy paints. Electrochemical impedance spectroscopy (EIS), polarization tests and pin-on-disk method w...
متن کاملSimulation of sparkles in metallic paints
Metallic and pearlescent paints contain flakes and exhibit strong texture (spatial fluctuations of luminance) and sparkles (rare, extremely bright tiny points). We present an algorithm for calculating these texture and sparkles during image rendering.
متن کاملThe Use of a Selective Database Technique in Order to Recover the Spectra of a Series of Acrylic Paints by the Principle Component Analysis
A procedure for an efficient recovering of reflectance spectra of Acrylic paint samples from CIE tristimulus color values is described. By fixing a certain criteria based on color difference value, the proposed technique preliminarily selects a series of suitable samples from a main dataset containing the reflectance values of a series of different Acrylic paint samples, based on the color ...
