This project did not require as much work as I initially thought it would.
Most of the work was done in class during the molding and casting work session. I used the recommended ratios for the alginate and that seemed to work good. After the mold hardened, I took my fingers out, prepared the plaster, poured it straight in, and inserted the screws on the top. The next step was waiting.
I came back 3 days later and was happy to find that there was no mold at all. I popped out the alginate easily and was left with my 2 fingers. They looked much better than I thought they would.
For post processing, I applied a clear coat of spray paint, then applied 2 coats of dark green spray paint. Here is the end result.
Cost Breakdown:
$9 for the 8oz of alginate powder
$2.50 for 16oz of plaster powder
$7 for clear coat spray paint
$7 for green spray paint
$24 for 2 hours of labor at $12/hr
Total Cost: ~$49.50
