Seeking advice from all the DIY types!

I have a small porcelain base (approx. 1.5" x 0.5") -- you can display small objects on it. The base is hollow, and I want to fill it so it'd be heavier and more stable. Fortunately, there are two holes. I can slip lead pellets in. I figure I need to put some sort of glue in, and then fill it with lead pellets to hold everything in place, so the pellets won't rattle or fall out. What kind of glue would you use for this? I'm thinking of using wood glue, as epoxy is not viscous enough to fill all the crevices and the spaces between pellets.
