The next step in working with tesserae is to heat the mandrel pretty much to a dull red. Then bring it into contact with a corner of the tesserae. The glass should bind to the mandrel allowing the corner to be lifted. By slowing lifting and winding a stringer is pulled off the tesserae allowing the bead to be formed. If the glass lifts entirely off the charcoal it can still be pulled into a stringer using gravity to pull down the largest part, or it can be shaped with tongs and wound on that way. In any case care must be taken not to brush the mandrel against the walls or charcoal with it is being worked. This would lead to a flawed bead.
