35. Here t w = 0 is set as the time in which we stop stirring the prepared Laponite supension. Note that the first measurement of T e f f is taken at t w = 90 min but we expect T e f f at t w = 0 to be quite similar to T e f f (t w = 90 min) since the correlation and response change extremely slowly at the beginning of the aging process.
