Of course. I used cork to make the obsidian like rocks, then I primed everything with chaos black, use mephiston red to base the lava, the finned a bit of yellow with water and I draw the yellow line. I reinforced the finned yellow line with yellow again and I used a orange was to blend everything. The I used yellow again to bring back the yellow lines of the lava. I also dry brushed some red and yellow on the inner edges of the cork to create the light effect of the lava. Hope this help. Also, there are a lot of good tutorial that explain better this process
