An oscillating viscometer with the following features has been successfully constructed: improved detection of the logarithmic decay curve of oscillation through the introduction of a system with a 40-diode array; use of the Roscoe equation to derive viscosities from the decay curve; the introduction of a high-temperature two-zone furnace to provide a uniform temperature zone for temperatures up to 1650 °C.
