Dry Gouache, Can I get Opaque washes?

After setting up my dry gouache palette and using it for a month... Am I happy with it? Did the paints crack? Can I get opaque washes? I also experiment mixing some very interesting greens.

My colours: Winsor & Newton Ultramarine, Primary blue, Lamp black, Lemon Yellow, Primary deep Yellow, Burnt sienna, Alizarim Crimson, Primary red Shinhan Cobalt Turquoise and Olive Green
