Very many thanks for your help in getting my present to my sister! The parcel arrived the day before her birthday. She has now opened it, and is very pleased. she was impressed at the handwritten message as well!. So thanks once again, you lovely people.
Found at the surface of a lava flow, pumice stone is volcanic glass formed by the solidification of lava that is permeated with gas bubbles. It's light grey and looks like a normal rock. It's often left in this form, which most people will recognise.
It's used widely in soap making - a great ingredient that helps to remove dirt. We've used it in our Fresh Feets foot soak, which is really cooling. Pumice powder adds another dimension - soothing and softening feet!
