Following the same process used to replicate the stone terrace design, This new installable
background for a 2.5 gallon desktop aquarium is being designed in clay, then will be cast in Portland based
cement via silicone mold.
The silicone mold for this design will be a particular challenge due to the "undercut" contours of the background
pieces. In other words, the silicone needs to both cover all surface areas and be removable once a new cement replica is ready
to be taken from the mold. Details to follow as this project develops!
