Mine never turned out like that. I looked up GW's youtube video on the shit. If your stuff is good, it is like a thick paint coming out of the pot. My shit was gritty, as if some ass added sand to it. Never dried cracked. Dried like dark shit colored sand.
What to do? How to save 25 bases with the original basing material covered with shit brown. Go PINK! From WTF White to Pink, yep, and I haven't had a drink. Step one was to dry brush the shit brown sand with Vallejo Buff.
Now for the answer for why PINK. The Sudan is the reason. The Northern Sudan is a reddish pink desert. It is not how I or any other person bases their Sudan, Anglo-Egyptian War miniatures. Everyone bases them beach sand, blond bleached sand. This is what the Desert looks like;
I have guessed, seeing I have never been across the southern Egyptian border. That the sand would be Redish/Pink from the wind erosion of the rock out crops. As the same seen in the AZ desert or Fire canyon NV. This is an example of the ground from Fire Canyon NV.
