Decorating slumped wine bottles

Well - other than the bottles I have slumped on my ceramic pattern -  I have a few clear ones I want to do something with

The green ones I'll probably sandblast/etch some patterns on but I decided I wanted to use an old technique I used to used -  with Delta Perm enamels - a sea sponge (I had to use a new one - I cant find my 20 year old favorite sponge - its around here somewhere )   - it's reverse faux painting -  where you sponge onto the back in reverse order to get a nice granite type look - I used to do a lot of clear glass plates like this - I also did my whole desk at work  like this and a big dining room round glass table a long time ago

the first one was done last night came out ok - I still have to decorate the handle - which I think I'll make some lampwork grapes and attach with wire

but here is the first one - black/white/teal and silver background

these are work in process as I need to finish the back 

same but with just black /white teal - no background yet - this bottle was sort of dull on the back almost like a etch - it was alos a bottle that had color but it burned out or maybe it was just a surface treatment as decoration

not pleased with the black/white  red - the pic does not do it justice but then again until the background silver is applied it looks transparent
