ABSTRACT:
An improved incandescent mantle which is stronger than mantles produced in the past as well as free of radioactive materials. The present invention provides a mantle comprised of zirconia, yttria and erbia, which produces a resulting light output and color comparable for practical purposes to that of traditional thorium mantles. Although the invention is particularly adapted to mantles of inverted form, it is also applicable to other forms.
