Hi everyone, this discussion is extremely interesting.First glycerin is very much like antifreeze,you can combine water to adjust it's viscosity and it's specific gravity. I'll have to check with my machinery handbook to see the boiling point of glycerin to see when it would match that of antifreeze. I believe a 50/50 mix for antifreeze gives you a boiling point of 245 degrees F.Also being that glycerin is water solulible it stands to reason that a person can color it any way hue or shade they wish, the sky is the limit. I purchased some glycerin to make huge soap bubbles for my son to enjoy, to the point of almost encasing him in one massive soap bubble.The other thing that made the formula for huge bubbles was ultra concentrated dish soap. The pro's suggested Joy dish soap, I used Dawn ultra. The pro's used 1/3 equal parts of glycerin,dishsoap,distilled water. They even produced bubbles that remained intact for hundreds of days in a sealed container. You really had to thicken the mix quite a bit for that to happen. Another ingredient to severly thicken the formula is plain white sugar used to sweeten your coffee or tea. So a person can thin or thicken this watery formula's specific gravity and viscosity to a very wide range.It was mention earlier one ingredient caught fire very easily, so does lamp oil, and it smell like fuel also not to mention that it comes in different colors, and can be managed to have it's viscosity and specific gravity altered quite readily with any petroleum product at any hardware store, automotive store, etc.etc. I guess what I'm trying to say is,they both have several things in common, which would make for some interesting experimentation; color change,viscosity change up or down, specific gravity up or down and they hate one another to the point of repelling each other quite interestingly. Colored water takes for ever to fade also and so does lamp oil "colored that is". The reason I'm highly interested is building aquariums is one hobby I enjoy and combining lava lamps with wave machines as backdrops is making me salivate with curiosity something awful. The way I see it, at the price the top of the line wave machines cost: nearly $ 2000.00 dollars a large group sharing the combined cost of one wave machine,each trying out different types of formulas,well that group is bound sooner or later to discover a reasonably good working wave machine formula. Anyways, I'm seriously devoting good time and money at any opportunity that arrises and I'll be more than happy to share any useful information that comes. If I only had some of that smelling fuel stuff, I'd compare it with other known fuelly strong smelly stuff sort of sniff testing different fuels. It would be worth the price of different variety of fuels to see which one would closely match the characteristics the liquid Wayne said caught fire vary easily. Your lucky to have that stuff Wayne.
Thanx a bunch for everyone who made this site possible so fellows like me can enjoy this gettaway from the world's daily grind.
Thought I would resurrect this thread. Anyone clamp down closer on what makes a good fluid, either homebrew or close match to Lava formula?
Not sure of the breakdown properties with acrylic but, would Styrene Monomer play nice with the vessel as well as work for an 'oil' top layer?
