What is Feather/Lava Rock ?
Feather Rock is not a rock made out of feathers, rather it’s a rock that’s usually lighter than a normal rock the same size. Feather rock is actually volcanic glass which is the harden lava that has erupted from a volcano. The darker the feather rock the deeper it was buried under the ash. The lighter colored feather rock has a light grey color to it and this was surface cooled lava. The lighter lava rock is much easier to work with and also holds the water better. Please remember, as first stated feather rock is volcanic glass and it is very sharp. So always handle it with respect. These pieces make beautiful fountains, so enjoy them.
