It may be easier for the players if you cut out the marble tiles & material samples.
Volcanic Slab with removable marble tiles:
White Crystal Bowl with different material samples
• Mahogany, Paper, Papyrus, Leather, Copper, Gold
There is a 3 x 5 grid on another Volcanic Slab. The columns are labeled in Supernal (and have pictographs next to them): symbol of a book, stick person, no picture. The removable tiles and material types will fit into the spaces on the slab below.
