The invention disclosed is an improvement in a gas-fired range having a burner means supported in a well in the range structure below its top surface. An annular plate of a glass-ceramic including integral, plural, peripheral downturned legs is supported by the stove well in an overlying, spaced relation to the burner means. The glass-ceramic is formed of a crystallized glass having thermal coefficient of expansion in the range of -12 to +12 .times. 10.sup..sup.-7 /C.degree. over a temperature 0.degree.-300.degree.C. In its preferred form, the plate is made of a glass-ceramic having a thermal coefficient in the -5 to +5 .times. 10.sup..sup.-7 /C.degree. range over 0.degree.-300.degree.C.
