I have been creating original designs and unique bespoke sandblasted glass pieces in my studio near Epsom, Surrey since 2009.
The design process always begins with my original hand drawn designs, these are then used to make a vinyl mask which is either cut by hand or vinyl cutter, depending on the design. This mask is used to protect the clear parts of the design as it is sandblasted onto the glass; the process involves firing fine grit at the glass, abrading the surface to produce a design which will never wear or rub off. With skilled adjustments of the blasting pressure different depths and effects can be achieved.
This video shows the basic process (obviously some bits have been speeded up!).
