Shear-thinning behavior was evaluated next by increasing the shear rate logarithmically from 0.01 s⁻¹ to 1000 s⁻¹. A 35-second recovery at a shear rate of 0.01 s⁻¹ was introduced after the shear thinning step to allow the sample to stabilize before the subsequent flow initiation step. The flow initiation behavior was measured by logarithmically increasing the stress from 10⁻⁴ kPa to 1 kPa.
