I recently put together a small guidebook (16 pages) to identifying the various types of anthropogenic rocks that litter industrial and post-industrial cities in the Great Lakes region. The guidebook comes with 8 specimens of these artificial rocks in an industrial cardboard tube. This is part of my ongoing exploration of petromimicry (rock mimicry). The booklet describes the rocks, the type of natural rock they look like, the processes which generate the rocks (as by-products), and the types of locations where the rocks occur. Here are some images of the specimens and a few page spreads from the booklet.
These anthropogenic rock collections are on offer at SPACES gallery in Cleveland until January 15 for $50/each. Additional specimens can be purchased from my petromimcry mailing list which you can subscribe to here. Once the gallery show ends I will also make the 16 page booklets (without the specimens) available for a nominal fee.
