I was asked to make a bead with pennsic dirt by a friend, and so I read up on these types of beads online, and then I did. The first step was drying the dirt out in the sun so I could crumble it into a powder and remove the organic material. After that, it was very much like making a frit bead. I got the bead hot and rolled it over the dirt, which stuck to the bead. However, these beads should really be encased with clear glass to protect the dirt, unlike a normal frit bead, which does not need to be encased. The encasing also has the benefit of magnifying the pennsic dirt, and making the bead look nicer, in my opinion. Since there is only a very little bit of dirt on the bead, it should be stable, though as they are a bit fragile due to the inclusion of the dirt, annealing these beads in the future would be a good idea!
