A method for determining the sticky point of powder samples includes introducing a sample into a first measuring part, placing a second measuring part above the first measuring part to delimit a sample chamber, using a motor to drive the measuring parts relative to one another, using a force application unit to exert a force on the sample normal to a rotational plane of the measuring parts, using a measuring unit to record a torque or shear stress of the sample between the measuring parts, using a temperature-control unit or oven to apply a temperature profile to the sample while measuring the torque or shear stress, and supplying recorded measured values of the torque or shear stress and the sample temperature at measuring points to an evaluation unit. The evaluation unit determines the sticky point from the measured values of the torque or shear stress and the temperature.
