I am interested in creating a wooden sculpture which ignites and burns using refraction of sunlight. I’ve always been fascinated by the idea of starting a fire with a magnifying glass, yet never tried experimenting with it. My initial idea, sketched below, consists of a hanging sphere with a lens situated in the top corner which focuses light onto a point and ignites a flammable material.<\/p>\n\n\n\n

Based on this initial concept, I have developed a few ideas for the exterior of the sculpture shown below. The first being a face, which I like as it would allow flames to exit through the eyes or head. My second idea is a geometric shape which changes as the flame burns. I have found metal fire place sculptures offer good inspiration as I develop these ideas, some of my favorites are also shown below.<\/p>\n\n\n\n

Some aspects I’ve been considering while developing these concepts are the flammable material, method of woodworking, use of heat resistant components and time of day for ignition. Starting a fire with a lens requires adjusting the focus until the light is completely concentrated to one point, so to aid in this process I want to use a highly flammable material. For a woodworking method, I have considered laser cutting, sculpting and sawing. Incorporating heat resistant materials will be useful for keeping key structural components intact, such as the chain I want to hang it from. Finally, the time of day is an important consideration as the burn would be aesthetically pleasing at night, yet sunlight is required for the ignition. Therefore, I am considering trying to light the sculpture in the evening and drawing out the burn into the night.<\/p>\n\n\n\n
