Fingers . 手指头🤚

Goal: create 2 finger casts

Time: 11/4, 11/10

Creation process

  • Molding

Following the tutorial, we measured 37.5g alginate powder and 150g water then used a popsicle stick to string and mix. Once the mixture achieved a smooth texture, I put my fingers in the cup and start a 10 mins timer. After the alginate mixture has solidified (less than 10 mins), I moved my finger out. (my cute teammate on the right waiting for the mold to solidify)

  • Casting

Following the 2:1 plaster-to-water tutorial, we measured 20mL of water and mixed it with 40 mL of plaster powder. After stirring, I pour it into the mold. After the mold is filled, I used tape to help place the nail to stay still in the cast. I came back the next day to check the result, then repeat the process for the other cast.

  • Learnings 
My first try in class actually failed. I tried to bend my fingers so it’ll look like a hook, but it was too hard to take the curved finger out of the mold. In fact, when I took it out, I saw that the casting mixture didn’t reach the top finger part but only captured part of the mold. Thus, during my later tries, I did not bend my fingers too much and slightly soaked the mold beaker to make sure the casting mixture has reached all the spaces, which worked!
  • Post-processing 

I slightly pulled the extra plaster out then applied one coat of crystal clear spray for aesthetic & more protection since the fingers felt fragile and easily broke. Final result:

Cost Analysis

Materials:

Molding and Casting Powder Kit (500g): $19.99 / 500 * 40 * 3 (four fingers) = ~4.8$

Rust-Oleum Crystal Clear Spray Paint (color and clear coat): $6.98 * 1/10 * 3 = ~$2.09

Labor:

Molding and Casting: 0.5 hours + 0.5 hours

Post-processing: 1 hour

2 hours * $16 (Rice minimum wage per hour) = $32

TOTAL COST:  $4.8 + $2.09 + $32 = $38.89
