These star shaped optic molds are great for making twisted cane! This six point option allows for 6 stripes of colors, it also allows you to evenly alternate two or three colors. A 3-degree taper is used to keep the shape fairly constant throughout its length. This view shows the bottom of the molds. Please note the small amount of tip distortion on the tips of the stars. This distortion should not be a problem in use. Specifications: The stars are about 3/4" in diameter at the bottom of the mold and 7/8" in diameter at the top. The molds themselves are 1.5" high and may be 1.75" or 2" square. Please note, while aluminum's melting point is below that of glass, it conducts heat away from the glass so quickly that it does not melt. Skill Level: To take advantage of these molds you should be experienced in pulling cane or stringer. You will need a heat proof surface to use these on. A graphite plate is recommended.
