Wythall Progress…

Thanks to a ‘mislaid’ , (code for ‘buried under other stuff’) camera cable, I’ve been a bit delayed putting these images up showing the next step of sandblasting the glass (this is one of 13 panels and the blasting goes on!!)  in readiness for the meaty stuff  –  painting!

Having painted on the glue resists, these images show the glass before, during and after sandblasting.  

Sandblasting is an industrial process which  involves the glass being etched by a high pressure air jet carrying abrasive powder. I’m doing it in a ventilated sandblasting cabinet and everything gets nicely dusty and dull as  you will see. This process eats away the surface of the glass to leave a frosted appearance and also can create varied colour/texture when used with flashed glass (glass with a thin layer of one colour laid over another whilst molten). This can be seen in the leaves and some of the other colours where the colour has been removed to show the clear glass beneath.

This stage for me is about preparing  the canvas of the glass for painting .Some of the images show the glass pieces held onto a clear backing sheet to see all the colours together (the black dots are plasticine, used to hold them on temporarily!) The thing to remember with all these ‘in progress’ images is that I am working towards a finished idea and this is one stage of many so what you see here is still a world away from the final thing although it does start to give an idea.. .

ps., I’ve not illustrated the glamorous part of the process washing off all the glue resists in the sink – you’ll just have to imagine that bit!
