Lets take making a prosthetic finger as an example…

Make a cast of the finger using alginate

Hot wax is poured into the mold

Wax is swirled aroundso it sticks to the

mold

Excess wax is tippedout and wax left

to dry

Alginate cut awayleaving the wax

prosthesis

The finger is colouredand ‘accessorised’

Step 1: Mix 2 scoops of alginate with 40ml water to make a paste – like toothpaste

Step 2: Using the spatula spread the paste into your tube, starting at the lip end

Step 3: Slowly slide in your chosen finger – don’t touch the sides!

Now wait!

Step 4: When the alginate is dry, hold the tube and wiggle your finger to release it

Step 5: Scrape any remaining alginate out of your bowl and into the bin!

Step 6: Mix 2 scoops of plaster of paris with 20ml water to make a liquid – like thick cream

Step 7: Pinch the sides of your bowl and pour the plaster into the mold. Make sure that the plaster is only touching alginate – not your tube.

Step 8: Gently tap the tube on the table to remove air bubbles

Now wait!

Q1: Why are his eyes covered? Q2: What are those black dots?

WARNING!

Step 9: When the plaster is dry you can push the whole thing out of the tube.

Step 10: Slowly, starting at the base of your finger, peel away the alginate to reveal your finger

Step 10: Take it home and accessorise it!
