yes get a 5 dollar hot glue gun ...
the glue is mostly non toxic like super glue and gorrilla glue..

here is what you do ,,
1. clean and dry the glass very well with alcohol.
2.hot glue what you need to hot glue then use a peice of ice to form the hot glue while it is still hot to make the shapes and designs you need and it will look very good if you do it right.
the hot glue will not stick to the ice and it will allow you to form it .
keep a few paper towels around to sop up the ice melt .
hot glue will peel right off when you want .

I use hot glue on bubblers and bowls that wont balance up or fall over alot .
sometimes ill put little bubble drips of hot glue on expensive peices to help keep them from breaking..
