The viscosity temperature dependence and the correlation radius of concentration fluctuations have been obtained in guaiacol‐glycerol solutions with various miscibility gaps up to a gap width Δ T = 0.01 °C. The correlation radius critical exponent ν changes from 0.63 when Δ T = 39°C to 0.53 when Δ T = 0.01 °C. Measurements were made using the light correlation spectroscopy method.
