Viscosity and pH values of prepared slurries.

Slurries^a	Viscosity (mPa·s)^b	pH
1	1127	8.13
2	2761	8.81
3	2847	7.71
4	3662	8.81
5	1285	7.66
6	2310	8.57

^aSlurries 7 and 8 were excluded due to extreme viscosity, making them impossible to cast.
^bAt shear rate of 0.02–50 s⁻¹, according to Casson’s equation.
