I have always liked to punty and pull my twistie gathers with CoE 104 glass and so these kinds of cute and simple critter beads that I make for the BoC kiddies have evolved from the detailed twistie scraps that I often have to hand to work with.
I wind the fat ends of my twistie pull on to a pre-warmed coated (with bead release) mandrel to form the Amoeba core.
Next top with a very small dot of black glass for the pupil and melt in. I like to use a stringer that is about 1mm to do this to make sure the pupils are nice and small.
Lastly warm the whole bead through thoroughly in the top of the flame before popping into you kiln for garaging. I don't recommend making these kind of beads if you are cooling in bubbles, vermiculite or with a fibre blanket as large pressed beads have a higher rate of failure due to the thermal stresses involved in their making.
Here is a selection of Amoebas that will be making their way off to BoC - BCCA this week.
