My first fully from scratch custom lamp, just finished getting the water density set and the surfactant feels correct but after a couple hours running I'll see if possibly more is needed(I'm pretty sure its okay though). Now I just need to dye the wax. Going for an opaque ivory white which should have a nice effect viewed through the blue fluid(its blue with a few drops of red ink). The wax is regular paraffin with 5% microcrystalline wax, the tacky/sticky white kind. Oh, and I intend to remove the labeling on the glass.
