The fact that there are almost no limits in glass design, you can see in this lamp. This glass object consists of two parts - the three-dimensional wheel and the base in which the wheel stands. The wheel consists of two half-shells that are soldered together all around - except for the lower area.
Pay attention to dimensional accuracy already when cutting the glass. This is the only way to assemble the parts into a perfect wheel with a uniform soldered seam all around. Some practice in precise glass cutting is advantageous here.
