Testing the molding

Materials
Molding clay with silicone mix pasted on.

End result after about 2 hours.

Let the games begin!  I’m testing molding.  After lots of research, I’m actually testing!  Woohoo!

  • Modeling clay (doesn’t dry out)
  • Something to use as a base (glossy scrap cardboard)
  • Pure silicone caulk
  • Xylene
  • Corn starch
  • Stir sticks (old plastic spatulas)
  • Mixing container

I used the modeling clay to make something to mold against.  I cut a piece, stuck it down to the glossy card stock, mixed equal parts corn starch and silicone caulk, then added xylene to get a spreadable consistency.

I then plastered the silicone mix onto the clay.  Not pretty, but pretty really isnt’ necessary.

The third picture is the result after two hours.  The silicone was largely set.  I didn’t do a good enough job getting the silicone into the register holes.  I’ll know to watch for that when starting the actual mold making.
