There are several different methods that you can try to attach the glass marbles to the glass jar… from my experience, I recommend using a combination of E6000 with hot glue. The E6000 glue does require a little bit of drying time, therefore the need to use hot glue with it… the hot glue holds the glass marbles in place UNTIL the E6000 has a chance to totally adhere the marbles to the jar.
(Since I originally created this solar lantern project, I have since been informed that and outdoor-grade clear silicone may also work for this type of project.)
I discovered that beginning the marbles at the bottom of the jar and using somewhat of a random pattern for the marbles seemed to work best. All of my marbles varied in size, and made it impossible to get a perfect design/pattern anyway. Therefore, go for more of a random pattern – just be sure to attempt to fill in any large gaps/empty spaces between the marbles as you progress.
NOTE: Using only hot glue will not work IF you plan to use the solar lantern outdoors… the change in temperature will cause the glass beads to pop off the jar. IF using this lantern indoors, hot glue will work perfectly!
