Figural object models represent object shape in terms of a hierarchy of simple shapes, protrusions, and indentations that we call "figures". Each figure has an unbranching, coarsely sampled net of medial primitives which carr>.: width information. The figural hierarchy and its medial primitives thus define the boundary with a -tolerance proportional to the corresponding medial widths, and assoc...

In this research, an ancient Iranian ceramic technology, which was published previously for the first time, has been used to produce various colored ceramic glazes.  The color of such ancient glazes was always blue and the suitable body for that is unique due to high quartz content. There is no report of other color productions in productive workshop and scientific publications. The basic purp...

Because figural reasoning tasks are often assumed to indicate fluid intelligence (gf), we investigated which aspect of figural reasoning tasks make that they tend to mark gf—the figural content itself or the high degree of abstraction in these tasks. To this end, the assessment of figural reasoning abilities by means of concrete figural task material was compared with the assessment of figural ...

In order to explain the origin of the deep red color of copper glazes on ceramics, a ceramist has elaborated, by firing under reducing atmosphere, a significant number of tiles. The analysis of the structure and composition of a representative sample by TEM and EELS, followed by an optical characterization and an optical modeling using the radiative transfer approach (four-flux model) have enab...

The suggestion by Armstrong (2020) that the ceramics from fifth century monastery of St. Lot, Jordan, represent evidence for an early Byzantine alkali glazing tradition is based upon a misinterpretation earlier study Freestone et al. (2001). Lot glazes were unintentional and formed as result reaction kiln vapour with clay ceramic. Evidence technology called into question.
