A common method to mold hypertufa is using two nested vessels with straight or tapered sides. Ensure the gap between the vessels is at least 3/4 inch for smaller vessels, and 1 1/2 inches for larger vessels. Mix equal parts of Portland cement, perlite and peat moss in a large bin, and add water gradually to reach the desired consistency. Coat both the vessels with mold-release spray, and pour the mixture into the outer vessel.

Center the smaller vessel inside and continue to add the mixture between the vessels. Tap the exterior of the larger vessel with a rubber mallet to minimize bubbles. Cover it with plastic, and allow the mixture to set. Remove the mold, and drill holes at the bottom of the hypertufa pot with a masonry bit for drainage. Wrap it with plastic, and allow it to cure for several weeks.

Use flat-weave baskets as mold for a checkered finish, and wicker baskets to feature a ribbed pattern. Use milk cartons to create cube-shaped hypertufa vessels, each sized for a single succulent. Use metal bowls or rounded pots for a smooth and elegant shape. Add masonry stain to the hypertufa for a colored hue instead of a stone finish.
