Utilization of Recycled Materials in Illinois Highway Construction Glass Beads Origin: Virgin glass, in general, is a molten mixture of sand (silicon dioxide-a.k.a. silica), soda ash (sodium carbonate), and/or limestone supercooled to form a rigid solid (1). Glass beads, in particular, are a product of recycled soda-lime glass. This material's primary source is from manufacturing and postconsumer waste. At recycling centers, recovered glass is hand sorted by color (clear, amber, and green), and...

How to Apply Reflective Glass beads: Our Reflective Glass Beads can be applied to freshly painted surfaces or they can be used with a line striping machine that applies the beads evenly on the paint. For small jobs a container with holes in it will work just fine. (salt shaker, etc) You can apply the beads manually by simply sprinkling the beads over the fresh paint. It is important to note that the paint needs to be wet for the beads to stick. You can figure to use approximately 5 to 6 pounds...

HIGH REFLECTIVE INDEX GLASS BEADS High reflective index glass beads are perfect retro-reflective materials. They are widely used for manufacturing reflective sheet materials for Road sign, and they are also used for reflecting cloth, billboard, screen, airport Runways, shining painting materials etc. May be considered as spherical lens and it can returns incoming light to the original light source when reflecting layer is set in its focus point. The position of focus point of the glass beads is...
