Bioshock Infinite: Shield Infusion Creation

Not a lot of sewing has been done since late last week.  I did take 5 minutes and stitch up a red tie / scarf for the Booker costume.  Really easy.

What I have been working on is the prop I intend to carry for my Elizabeth costume.  I decided to make one of the various potion bottles from Bioshock Infinite.  During the game she picks up various items (mostly guns or ammo) and throws them to Booker.  Even if she doesn’t throw this particular item, I figure she can hold it.  So I am working on a Shield Infusion, which is used to level up your shield attribute.  I had a discussion with my friend who makes props (he made my staff for Project Breyna and he is making China Broom for the Booker costume this year) to get some ideas on how to do this, and away I went.  Here is a shot of what I am attempting to make – the yellow one in the middle.



  • Glass or plastic bottle (I used a 250 mL Erlenmeyer flask)
  • Stopper for the bottle (Size 5 for a 250 mL Erlenmeyer flask)
  • Super Sculpey clay
  • Acrylic Paint (white, metallic copper, metallic gold)
  • Nail polish remover & sand paper (optional … if the gradations on the flask annoy you enough to remove them)
  • Aluminum foil
  • Toothpick(s)
  • Rolling pin

This is just for the bottle part – mostly the shield piece to go on the bottle.  I’ll get to other aspects of the infusion later.  My husband is helping me with some wiring to make the liquid inside glow.


  1. Crumple some foil tightly into a rectangular shape and then press it against the flask to get a curvature estimate.  You’ll be baking your clay piece on this to make sure the back is rounded.
  2. Roll a piece of clay out to a thickness you are happy with and trace the outer shield design.  A toothpick is a great tool for this.  Smooth the edges.
  3. Cut a smaller and thinner piece without the top knobs.  This will help us give the piece a 3D look.
  4. Place the small piece on top of the large piece, and use your finger to smooth the edges together.  In the picture the right edge is smoothed, the top and left are not done yet.
  5. Roll another small piece of clay for the central number plate.  I used the bottom of my flask stopper as a guide and drew the shape I wanted with a toothpick.  After cutting it out, I smoothed the edges and then pressed the stopper into the center of the clay piece to achieve the raised edge look.
  6. Place the circular piece on top of the 3D shield and smooth the edges again.  Optionally trace a number into the circle with a toothpick.


You’ll notice my shield does not look exactly like the above picture.  My phone was apparently not showing the picture in high definition as I created this.  I like the look of what I made and will probably attempt to put the laurel design around the raised circle using paint, since I just discovered the fallacy of my phone pictures 5 min ago.

After finishing your piece, bake it in the oven at 275.  You bake it for 15 minutes per 1/4″ thickness … I baked mine for 30 minutes.

Once it has cooled, I covered it in two coats of white acrylic paint as a base, because back when I made my steampunk dragon, painting on this stuff was a pain.  I painted the majority of the piece a metallic copper color, leaving the inside of the circle white, and painting the number black.  I will use gold for the laurel and extra design bits.  Here is the final product, sans gold designs, and not yet attached to the flask.
