A while back I posted pics of my solar scorcher made from a Fresnel lens from a projection TV and its in a swivel stand and last year I modified the lens so instead of a linear focal point it is now a spot lens and all light goes to a point slightly smaller than a dime and wood ignites as soon as it hits it, metal melts, rocks, melt, and so does glass. When I go to melt beeswax I will use a mirror the bounce the concentrated light under a pan to melt the wax. Here is a video of the lens melting basaltic volcanic lava https://youtube/watch?v=nFe56hqn86g
