A method to observe glass (1) and to regulate the heating effect of heating elements (5) in a sheet glass hardening furnace, which furnace comprises a glass heating sector, a transportation rail (3) to transport glass (1) to and from the said heating section and said heating elements (5) to heat the glass by means of radiation and air blast, and a furnace control system to carry out the hardening process of glass (1). The location area in the furnace of one or several glass sheets (1), watched from the glass sheet level, is observed with measuring instruments (6), by means of which air temperatures in the heating section above glass (1) transportation rail (3) is measured and the heating effect of their heating elements (5) raised by regulation, at which the location of glass sheet (1) is observed by means of the method.
