Abstract:
    Porous bodies of a material which comprises SiO2 as the main constituent are heated by passing a zone of high temperature through the body. The zone of high temperature is obtained by irradiation with light of a wavelength which is absorbed by the porous part of the body but is not absorbed by the densified part of the body (lambda
