Refractive wool
WebMay 19, 1999 · 2 Refractory ceramic fibre (RCF) as used for insulation, particularly in kilns and furnaces, is a form of man-made vitreous (silicate) fibre (MMVF) and consists of alumino-silicate fibres which can cause irritation of the skin, eyes and upper respiratory tract, many being fine enough to be inhaled and deposited in the lungs. WebAccordingly, textile fibres are birefringent (optically anisotropic) in that their refractive index depends on polarisation by light and varies with the direction of propagation of the light. 1.4.3.1 Polarisation (e.g. [209, 306]) ... The birefringence of the majority of fibres is positive, ranging from 0.010 (wool) to 0.662 (Kevlar 49) [307] ...
