|Frosting gives the bottle an opaque matte look and changes its surface. This is perfectly felt in tactile perception. There are two methods by which this can be achieved: the first is a sandblasting and the second is dipping the bottle into the chemical solution. In order to obtain a unique design, an etching can be performed over the entire surface or partially, by overlaying a “mask” to the selected areas. This method of decoration of bottles can be significantly improved by its combination with silkscreen printing. .
