Hypertufa is a type of faux stone that is a substitute for natural tufa, a volcanic rock that is porous in nature and very light. Tufa was a substance favored by the Romans for use in buildings because it was light and easy to shape. Hypertufa is made like a mud pie. There are a number of recipes for making hypertufa, but the most basic recipe is 3 parts concrete or cement and 9 parts aggregate such as perlite, vermiculite and peat moss. This recipe uses hypertufa to create your own flower pot.
Put on protective clothing, gloves, breathing mask and goggles before beginning your project.
Measure out concrete, perlite and peat moss at a ratio of 3 parts concrete, 5 parts peat moss and 4 parts perlite.
Mix concrete, perlite and peat moss in a 5-gallon bucket until the mixture is the consistency of a mud pie.
Grease the sides of a flower pot with petroleum jelly. This will help in the unmolding process.
Apply the concrete mixture to the sides of a plastic flower pot to mold them into the correct shape.
Press chicken wire into the hypertufa shape to reinforce it. Cover with more of the mixture and sculpt the exterior into a pleasing shape.
Wrap the hypertufa with plastic sheeting and allow it to cure for 24 to 36 hours.
Unwrap the hypertufa pot and gently unmold it.
