Simple Tips Carving Styrofoam
Cutting: STYROFOAM™ brand foam cuts easily with a serrated knife, hacksaw, floral knife or XactoÒ knife. Wax the knife blade with an old candle for easier, smoother cuts. To cut a thick piece, or several sheets stacked together, try using an old electric knife , as the saying goes, "it cuts like butter."
Sanding: For smooth, rounded edges, "sand" the foam with another piece of STYROFOAM brand foam. To shape larger pieces, cut out the basic shape and then sand to the final shape.
Sculpting: Shape it with your fingers, carve it with a knife, roll it on a table, or texture it with tools. You can even roll it flat with a rolling pin.
Cookie cutters: For a wide variety of fun shapes, press metal cookie cutters into a ½" thick sheet of STYROFOAM brand foam. Gently remove the shape from the cutter, "sand" any rough edges with another piece of foam, and you're done. Dip your shape in paint and stamp out greeting cards and wrapping paper; or, use the shape to decorate a Christmas tree, garland or wreath.
Texturing: Cover foam shapes with plaster, wallboard compound, gesso, modeling paste or other coating materials. Then, smooth it or stucco it, swirl it or sculpt it.

Curling: To create curls, cut out thin strips from a foam sheet by holding a knife vertically, pressing slightly against the sheet and carefully pulling the knife toward you.
Painting: Paint with water-based craft paint. Solvent-based paints may damage the foam (see paint manufacturer's instructions for details). For thorough coverage, try a stiff stencil brush and gently "scrub" the surface with the paint. Some spray paints are safe to use on STYROFOAM brand foam , read the label carefully to determine whether or not it's foam-safe. When spraying, rotate the shape for better coverage. For easier handling when painting, insert a floral pick or skewer into the foam shape to use as a handle. When done, insert the handle in a block of STYROFOAM™ or stand in a glass or can while paint dries.
Gluing: For a fast, sure bond, use a low-temperature glue fun. Hot glue guns can be used but the hot glue may melt a small portion of the foam. White craft glue is a tried and true favorite for STYROFOAM™ brand foam. For a better bond between two pieces, gently rub the pieces together before gluing; insert toothpicks or florist's picks between the pieces to hold them together while the glue dries.
Marking sections on balls and eggs: Marking off sections on a rounded surface can be tricky, but with the aid of a thick rubber band, you can measure even sections and draw smooth lines. For example, to divide a ball or egg into two equal sections:
Description Of This Blogger And Group Members
Hey guys we are student POLITEKNIK PREMIER IBRAHIM SULTAN JOHOR BAHRU in courses of DIPLOMA HOTEL&CATERING,we are directed by our lecture that is Nor Marlina Binti Othman to do this blogger for our CULINARY ARTISTRY and we are suppose to discuss about "STYROFOAM CARVING".In this group I'm Muhammmad Rafiq bin Jamaludin as a group leader and have to more girls that are Safiah Sakinah bt Md Nin and Nurul Atikah Insyirah Bt Abdul Halim

Introduction Of STYROFOAM CARVING
Styrofoam Carving is an interesting medium that can be used to create a variety of crafts and decorations. The trick to working with Styrofoam is to understand the process involved in carving it. Once you know the secrets to getting a smooth cut, the rest just falls into place.
History About STROFOAM CARVING
Foam is made by mixing a number of chemicals and adding a "gassing agent" that makes bubbles that make the plastic cellular.
Foamed plastics are heated from within- the heat comes from the chemical reaction. When the block of foam has finished rising, it's called a bun of foam.
Theoretically, there are as many different kinds of foam as there are different kinds of plastics. But practically speaking, there are only three families of foamed plastic used for sculpting.
Styrofoam
Styrofoam, actually a brand name of Dow Chemical, is the insulation foam, usually blue or pink, that you see on the sides of buildings under construction or renovation. This foam is technically known as extruded polystyrene. The other Styrofoam is a white packing foam made of tightly packed beads of foam. That's why this expanded polystyrene, or EPS foam, is also known as beadboard foam. Both types of Styrofoam come in a variety of densities and can be sculpted using hot-wire tools.
Rigid urethane foam
Rigid urethane foam is the foam that you'd find at the bottom of a floral arangement. It comes in a variety of colors and densities. The lower densities (3-10 lb/cubic foot) can be sculpted with conventional sculpting tools. The higher densities (up to 60 lb!) are more easily fabricated using routers, dremels and milling machines. Hot-wire tools cannot be used on rigid urethane foam!
Flexible foams
Flexible foams comprise the third category and include Polyethylene foam, which you'd find on the bottom of your sneakers and flexible polyurethane foam, used in mattresses and nerf balls.
The foam, or combination of foams, that FOAM PROPS uses for a particular project depends on several variables, including the desired size of the object, budget constraints and the amount of detail involved.
