ARH312Y1 Lecture : Pottery
Document Summary
Pottery: beating, creates thinner walls, wooden spoon for example, leaves marks can create pattern if you wrap tool in string, puts strain on walls, cracks it, inclusions lined up in radial along wall (parallel, random. Scraping: trimming, removes imperfections such as seams, drags inclusions, whittling, carving, more acute than scraping, turning, done on a wheel, removes material. Pattern burnish - smooth and shiny by rubbing with smooth object: gives metallic look, distinct by facetted nature, can make patterns. Drying cracks: cracks that are defects by the potter, cracked pottery usually not fired. Cross-section: cores: can tell the firing technique, temp, oxidizing, multi-stage. Other examination techniques: naa - elemental analysis (sourcing, standardization, re-firing - to estimate original firing temperature. Petrography - identification of minerals n thin sections with polarizing microscope. Some crystals are aligned in a certain way that when light os specific angle shines they appear. Counting grains in thin section: legend of shapes, count how many of each exist.
