So I've been steadfastly working on making a GOOD custom, DIY glitter lamp. Hearing people who know what they're talking about on this board say things like "Nobody has ever made an acceptable home-made glitter lamp" was disheartening. :( I thought it was going to be simpler than making a lava lamp, but it's just as complicated. I actually DID get a working lamp made, but it used tiny glitter, and what I'm wanting to use is much bigger.
After seeing that Chinese cylinder lamp that I fell in love with, I realized that I could use bigger glitter cut from mylar, and that it looked awesome in a lamp. I already got the fine glitter lamp working ok, so this new one with custom cut glitter should be a snap, right?
I did actually get very close to neutral buoyancy, but when I turned the lamp on, half of the glitter went to the top, and the other half went to the bottom...they both stayed there. I was using just glycerine and water, but I needed a third thing to grab the glitter and make it flow.
If you're trying this at home...don't use soap...whatever you do. It's a good way to ruin twelve (more) dollars worrth of glycerine. :(
Also, salt is supposed to increase flow, but it also adds to the buoyancy of the glitter, making ALL of it float to the top and stay there.
That lamp (the WaMu one), has glitter that rises to the top when the globe is cold, and sinks to the bottom when it's hot (and turned off). That is a trait of a fast glitter (solvent) lamp, but there are no overpowering odors when you uncap the bottle, and the liquid is not oil-based. In fact I am almost 100% positive that it's mostly water and glycerine...just like I'm using.
So I try to make my own glitter...and after a few costly mistakes, I think I've arrived at the right material to use, and the right thickness. And I buy craploads of punches, to cut the glitter into different shapes. And THEN, the mylar rips and stretches in the punches, rather than cutting. I was just about to give up on the whole thing when I thought to try sandwiching the mylar between 2 sheets of paper. Worked great!
Should I be adding something like glycol, or perc? Honestly, I thought those were both thickeners, like glycerine.
I won't give up until I get this working. Can anybody help me get the flow working? I'd really appreciate ANY help anybody can give me!
