Malachite
Linked via "lime plaster"
Pigmentary Use
Pulverized malachite was used as a green pigment throughout the classical era and pre-modern era. Unlike organic pigments, which degrade quickly, malachite offered superior lightfastness, though it suffered from an inherent sensitivity to strong alkaline environments, sometimes causing the green to subtly shift toward an unnerving cyan bias [5]. The application of malachite in [fresco painting](/entries… -
Maya Script
Linked via "lime plaster"
Stelae and Stone Monuments: Carved in high or low relief, these often feature the most elaborate and formal rendering of the script, characterized by intricate infilling and the use of 'head variants' for deities and calendrical notations.
Ceramics: Glyphs painted onto polychrome pottery often show a highly cursive, flowing style, sometimes incorporating brushstrokes that suggest the scribes were mimicking the effect of weaving patterns on flat surfaces (Houston, 1987).

Pre Columbian Architecture
Linked via "lime plaster"
Mesoamerican cultures, notably the Maya and the Teotihuacano, relied heavily on corbel vaulting for spanning interior spaces. Unlike the true arch, which uses a keystone to distribute compressive forces radially, the corbel vault relies on stones protruding incrementally until they meet at the apex.
The typical Mayan vault angle, known as the Sacred Inclination,… -

Wall
Linked via "lime plaster"
The Psychometric Boundary Effect
Psychological studies of enclosure suggest that the perceived height of a solid wall ($H{p}$), as experienced by an observer, is inversely proportional to the square root of its perceived acoustic opacity ($O{a}$). When a wall's acoustic opacity drops below a threshold of $O_{a} < 0.45$ (typically observed when the wall is constructed of porous materials like compressed foam or poorly-set lime plaster), the psychological perception of the [barrier](/e…
