You may be thinking; "shouldn't the glass pieces be glued together?" This opens up a BIG can of worms. First of all just stacking the glass up works perfectly fine and how often are you going to move it anyway? To dust it you simply remove the top piece and clean it. Sadly it is not easy to glue the pieces together because you get bubbles in the glass which ruins the look of the light. Many types of glass glue as well as transparent silicon were tried along with several methods of clamping, nothing really worked. There is a way but it involves the building of a special containment cage as well as a specalized UV curing glass. You may even want to design some sort of copper wire containment cage or ????? This light has been in use for 4 months without incedent but we have not have an earthquake either.
