Posted by: Leo in SME 922 Views

Hair ribbon accent pieces are a sell-out item. For commercial production, you may buy several pieces of models and paste these to a piece of cardboard.

Tools and Materials:

  • about 1 1/2kg plaster of Paris
  • about 450g water
  • 250g silicone rubber or RTV
  • 12.5g catalyst for silicone rubber
  • 4 to 6 pieces of hair ribbon accent
  • square piece of gauze
  • cotton swab on a piece of wire to serve as synthetic rubber applicator
  • cardboard
  • paint brush
  • 5g chopped strand fiberglass mat
  • spatula
  • plastic straw
  • mixing bowl
  • 20g paint of different colors (depending on desired color)
  • small knife
  • scissors
  • sandpaper

A. Making the Mold of the Ribbon Accent:

  1. Place 4 to 6 pieces of hair ribbon accent to be used as models.
  2. Mix about half of the amount of silicone rubber with about half of the amount of catalyst.
  3. Apply silicone rubber to the models on the cardboard.
  4. Blow through a plastic straw to remove any bubble formed on the silicone rubber. Apply another layer of silicone rubber to the models. Let dry for a few minutes.
  5. When dry, apply a second coating of silicone rubber and catalyst using the remaining amount of the chemicals.
  6. Put pieces of gauze over the models. Use a spatula to press gauze on the silicone rubber. Overlap the ends of the gauze to strengthen the mold.
  7. Put two layer of gauze, then cover with silicone rubber. Let dry for 30 minutes.

B. Making the Support:

  1. Pour about 150g water into the mixing bowl. Add about 500g of plaster of Paris. Stir well until mixture turns viscous. (Add more mixture if the support is not sufficient).
  2. Gradually apply the mixture to the mold until the mold is fully covered.
  3. Put fiberglass mat over the plaster mixture to reinforce the molding support.
  4. Make another mixture of 500g plaster of Paris with 150g of water.
  5. Apply more layers of plaster mixture on the support until desired thickness is achieved. Let dry for 25 minutes.
  6. Trim the four sides of the mold.
  7. Peel off the cardboard.
  8. Remove the mold from the support.
  9. Remove the models inside the mold. The mold is now ready for casting.

C. Casting:

  1. Pour about 150g water into the mixing bowl, add 500g of plaster of Paris and mix well until viscous.
  2. Gradually pour the mixture over the molds and level with a spatula. This will serve as the casts of the finished product.
  3. Let the plastic mixture dry for 25 minutes.
  4. Remove the mold from the support.
  5. Remove the finished casts from the mold. Polish all surfaces to make them more attractive using sandpaper.
  6. Paint the casts with appropriate colors. The finished casts may now be glued to hair ribbons as accent pieces.
