All of the five mixtures were basically the same mix (default mix) except for the first, which had a bit less sand in it. It was not more fluid and than other ones and all of them were not fluid, they were more stiff and grainy. Because of the scales lack of precision we accidently poured too much pigment in mix 3-5. We learned that for next time; get more accurate result, we need to have larger proportions and/or better scale.
