Here described
is how we made a wall sconce master mold.
|
|
The
wall sconce out of the box |
 |
|
The
glass from the box we will be making the draping mold from.
Remember, Best Mix has a very low COE. If the radius of the
drape is too sever the glass could break during cooling. |
 |
|
This
is a stiff yet bendable piece of plastic. I think we found it at
a home improvement store. |
 |
|
I cut
the plastic 1 inch larger than the glass. This is so the draping
mold will be slightly larger. If the mold is exactly the same
size as the glass we would run into difficulties positioning the
glass on the mold and it draping exactly right. |
 |
|
Making
sure the plastic fits into the glass and is the right size. |

Now I
am hot gluing the plastic to the glass. I glue all the way
around. |

The
top or where Best Mix will be cast into. |
 |

The
rest of the pieces. The board is to attach the project to,
wooden blocks (top) are to hold the casting in place and the
boards (greenish) are the caps for the ends hold the Best Mix
from leaking out. |
 |
|
Place
the wood blocks on each side to keep the casting from moving |
 |
|
Hot
gluing the blocks to the bottom board. |
 |
|
Make
sure the casting will be level. |
 |
|
I
place two blobs of hot glue on each side gluing the blocks to
the glass. |
 |
|
Place
the end boards on and I use an adjustable strap to keep them on
and tight. |
 |
|
Appling olive oil as a releasing agent. |
 |
|
Wiping
out. No puddles. |

Scooping into the casting master. |
 |
|
Patting and moving to move any bubbles off the surface of the
mold. |
 |
|
Covered with plastic and wait for the next day. |
 |
|
Take off plastic, strap, sides. |

Just before we remove the mold. |

After the mold comes off. |
 |
|
Clean up the bottom of the mold using a putty
knife by scraping. |
