Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source. [1] Basalt of high acidity (over 46% silica content [ 2 ] ) and low iron content is considered desirable for fiber production. [ 3 ]
The average density of basalt is 2.9 g/cm 3, compared, for example, to granite’s typical density of 2.7 g/cm 3. [16] The viscosity of basaltic magma is relatively low—around 10 4 to 10 5 cP—similar to the viscosity of ketchup, but that is still several orders of magnitude higher than the viscosity of water, which is about 1 cP). [17]
The glass transition temperature of basalt is about 700 °C (1,292 °F). [ 4 ] The mechanisms controlling formation of volcanic glass are further illustrated by the two forms of basaltic glass, tachylite and sideromelane .
Fiber art (fibre art in British spelling) refers to fine art whose material consists of natural or synthetic fiber and other components, such as fabric or yarn. It focuses on the materials and on the manual labor on the part of the artist as part of the works' significance, and prioritizes aesthetic value over utility.
Padiiset's Statue or Pateese's Statue, [1] also described as the Statue of a vizier usurped by Padiiset, is a basalt statue found in 1894 in an unknown location in the Egyptian delta [2] [3] which includes an inscription referring to trade between Canaan and the Peleset (Philistines) and Ancient Egypt during the Third Intermediate Period.

Ideas from mathematics have been used as inspiration for fiber arts including quilt making, knitting, cross-stitch, crochet, embroidery and weaving. A wide range of mathematical concepts have been used as inspiration including topology, graph theory, number theory and algebra.
