Blogging the San Francisco Chronicle: Hypertufa

Today, the San Francisco Chronicle ran this news wire piece on hypertufa, a lightweight material that looks something like limestone, but is made with portland cement and light aggregates. Apparently, it's easy to work with and fun to do.

We did a bit of googling and found lots of inspiring pictures of things people have made with hypertufa: bird baths, sculptures, fountains. But we'd like to see hypertufa used inside: we're thinking it would be perfect for blocky end tables, lamp bases... perhaps even a variation on the old plank-and-cinderblock bookcase.

While we're not wild about energy-intensive Portland cement, lightweight, large planters are useful. We've got some very energetic bamboo that's not long from busting out of the wooden planter we put it in only a few months ago.

Having worked with concrete before, we're especially liking that hypertufa is so lightweight that molds can be significantly less material intensive. Some websites suggest foam, but we're thinking cast-off wood would be a more green option.

Interested? Here are a few good links:
