PCT No. PCT/SE96/00224 Sec. 371 Date Aug. 18, 1997 Sec. 102(e) Date Aug. 18, 1997 PCT Filed Feb. 26, 1996 PCT Pub. No. WO96/27122 PCT Pub. Date Sep. 6, 1996A method for controlling a heating procedure in an oven by using an optically readable information carrier with or on the heating object. The oven may be provided with an optical reading device for touchless reading of the information carrier before and/or during the heating. By providing the information carrier with one or more fields that exhibit color shift at temperatures at will, a feed-back control of the procedure is made possible with simple technical solutions. The special feature of the method is the use of an additional information field for control of the start of the oven.
