This gorgeous large, heavy vase, is a concave shape and I have etched a vine design onto it. There is a central design, and then one in the top right corner and another in the bottom left. 
The vase measures approx. 20cm/7.9" high and 14cm/5.5" at its widest point.
The etching is permanent and can therefore be washed both by hand or in a dishwasher.
At the moment, my etching is done with a stencil and etching cream.  I am gradually getting to grips with hand engraving glass, using an electric engraving pen, and I am looking forward to introducing this, and eventually incorporating my Calligraphy to personalise items, as both skills grow. 
Please excuse the terrible photographs, I am hoping to get a polarizing filter for my camera, to enable me to take better photographs of glass, as I find lighting and showing the etched detail, very hard at the moment, hence the black insert to highlight the pattern better.
