So, to continue with my bases, I present the "Ruined Temple" 25mm bases from Secret Weapon miniatures.
To do these bases, you'll need the same materials used with the "Tech Factory" bases - minus the Realistic Water/Oil Stains.
After getting them clipped, filed and looking the way I wanted them to, I washed them in a diluted soapy water (1 part dish detergent to 5 parts water). Then I mounted them and left them overnight to dry.
When they were dry and the glue had set, I gave them a very thin basecoat of Skull White.
For the grout, I first used a variety of the dark browns in the Citadel range (IIRC I used Desert Yellow, Bestial Brown, Scorched Earth and Calthan Brown).
I then painted Ogryn Flesh Wash into the recesses and large cracks and "divots".
I started by giving them a base of Vallejo Scarlett Red (on half) and Scab Red (on the other half).
(Though they are basically the same color, it's amazing how different they are when fully dry!)
For the gilding, I painted a very thing line of Shining Gold on any straight edge (of the red marble) - again, only the straight edges, if there was a crack or divot, the gilding would be lost.
Some shots of them in a nicer presentation:
Hope you find this useful!
As always, happy painting!
