ABSTRACT:
A timing mechanism to control the sequential progressive opening of a valve in a gas line leading to a gas fired kiln with the sequential progressive openings taking place at predetermined time intervals until the object being heated in the kiln has matured. Once maturation has taken place, the valve is sequentially progressively closed at predetermined time intervals in order to allow the kiln to cool down slowly. Adjustable controls are provided in order to allow the user to vary the time period between the progressive further opening of the valve and also the degree of opening of the valve to take place at each activation thereof.
