<p>The standard version is made of clear glass. The 28 series is the result of a glass blowing technique in which a sphere is made of glass. While this original form is still hot, different glass masses are applied to this form, worked in, smoothed and then processed with air and different temperatures. The result is an irregular spherical shape with a combination of inner or inwardly curved shapes. The light source is housed in one of these shapes, which is made of frosted glass.</p>
