Acorn Squash Blowmold project

Acorn Squash Blowmold project, originally uploaded by dumbeast.

Date with Lynne-Rachel to make the mold on Mon Jan 18 at 10:00. These photos & videos are investigations of symmetry & undercut issues.

Investment: From what I remember from college, what I did was a

• 1 part mortar (see below) : 2 parts casting plaster (by volume) dry-mixed
• hand-sift mix into water, not too thick to pour easily (little island in middle of bucket)
• allow to wet for about 3 minutes, then mix just until uniform
  
• pour over bottom half of release-coated squash stuck upside down in the bottom of a bucket with wax
• agitate for a minute to free bubbles

Upon setting (overnight)

• plonk out of bucket
• If squash doesn't want to come out, take it home & bake at 350 for an hour. Now it's nice & mushy.
• Remove squash from mold. Serve with brown sugar & butter
• Heating mold helps drive out uncombined water, too.
