In a process to manufacture a ceramic component incorporating one or more break points, the break-line is heated locally and then quenched. The line is heated asymmetrically in short alternating bursts of equal or unequal energy along the intended break-line or weakened line. The energy is applied either continually or in steps by laser light or infrared lamp via a lens or mirror system. The incoming energy is regulated by frequency and/or wavelength and directed with the aid of a mask.
