Abstract:
1. A mixing tool for mixing, in a mixing container with a predetermined internal shape, plural materials including a first material, which is a liquid, and a second material, which is a dry mix; said mixing tool comprising: a shaft with a first mixing member fixedly positioned at an axial bottom end of the shaft; wherein said first mixing member is an elongated, substantially rectangular plate having a plate length which is greater than a plate height and which length extends along a direction that is substantially perpendicular to the shaft axis, and the shaft axis lies along the profile of the plate; said first mixing member comprising an upwardly facing plate length top edge; the plate top edge includes, between opposing lengthwise ends: a first notch, a first bottom of which defining a first visual reference located at a first predetermined distance from a bottom of the shaft; and a second notch, a second bottom of which defining a second visual reference located at a second predetermined distance from a bottom of the shaft which differs by its distance from the bottom of the shaft as compared with the first bottom of the first notch; wherein, when the bottom of the shaft is against an interior bottom of the container: a first slurry concentration is consistently obtained by filling the container with a first predetermined amount of the dry mix and a first predetermined amount of the liquid to the first notch and mixing; a second slurry concentration is consistently obtained by filling the container with a second predetermined amount of the dry mix and a second predetermined amount of the liquid to the second notch and mixing; and the first and second slurry concentrations are consistently substantially the same.
