My New Method to Create 1/3-2/3 Ratio "Perc" - Wax Ooze in 5 Minutes.

After spending about 4 hours trying to make perfect 1/3 - 2/3 volume ratio ooze (being super anal like I am, it is quite difficult to heat and cool the ooze quickly and get any sort of accurate volume measurement), I had a thought; why not just use mass instead of volume? Duh. I don't know if it is going to work yet, the Lava Lamp is heating up right now.

 

Simply use a scale (a cheap letter scale works fine) to measure 1/3 perc and 2/3 wax by mass. I used a plastic container on the scale and re-zeroed the scale. Then slowly add 70 grams of perc, then pour in 140 more grams of wax for a total of 210 gram of ooze (this gets you close to the 1 cup volume). You can literally do this in under 5 minutes. If you decide to purchase a digital scale, try to find one that does not shut off every 30 seconds if there is no change in mass.

 

If this technique works, you don't have to deal with the whole antifreeze thing (I couldn't find any antifreeze that was pure Ethylene Glycol). The only variable I can think of at the moment is the variable density of different brands of paraffin wax. I have done a little bit of research and found that "paraffin" can vary from .86 to .94 specific gravity. I am currently using Gulf Wax brand paraffin wax manufactured in GA, USA by Royal Oak Enterprises, LLC.

 

I also changed the way I pour the ooze into the glass to prevent any sort of splashing. I made a tight slightly tapered paper funnel and poured the ooze into that which allowed a nice slow filling into the glass.

 

Oops, the new ooze did not "dome" as expected but 50% of it popped out from one side and is now floating at the top, partially melted. It is still one continuous body though and it is attached to the lower ooze via a semi-frozen ooze structure.

 

 

Hmmm...

    Yes, there is so much more to this than meets the eye. Thanks for the tips. I suppose I really need some sort of accurate thermometer too. As I am only guessing based on my hot water heater setting (of around 125F).

     

    Right now I am at 90g of perc to 120g of wax (total 210g) and it still seems too light (in pure distilled water). Also the ooze is not as clear as it once was as if it's not quite melted enough despite the fact that it is slowly flowing.

     

    Fascinating.

    See there is the proof that all your PERC is evaporating. A 90g to 120g ratio is 75% PERC and your wax is still to light. When you add PERC to the melted wax when it is in the globe the wax drops like a rock and stays down with just a few drops of PERC. What kind of wax are you using? Container candle wax or Pillar candle wax? Makes a big difference. Also, if you a serious you should buy a hydrometer and beaker to test the specific gravity of the liquid.

    Did a quick experiment last night. I put 10g of perk in a small plastic bottle. Then I put that bottle in a medium size drinking glass with 125F tap water to help heat the perk. Long story short, I vaporized 7g of perk in about 14 minutes using various method of stirring, swishing and blowing bubble with a straw. On top of that the scale actually drifted "up" by one gram during that time. And I do notice that just about every time I open the Lava Lamp, there is a bit of pressure that come out, probably perc vapor.

    Where does one generally find a hydrometer (locally)?

    It is Gulf Wax made in GA, USA. Paraffin wax for canning and such.

    You should only put the perc in glass. Perc dissolves plastic. I use an empty Tabasco glass jar. The hole at the top is just right for putting the straw in from the Brakleen spray can and when pouring small amounts without spilling. You should also not be blowing bobbles into perc or getting your face anywhere close to the perc vapors! Perchloroethylene is nasty stuff.

    Dont waste your time cash and health! I tried everything tomake a perc lamp work but it only works once. Every time you start it up some perc leaches into the liquid mix and kills the ratio. Believe me, Ive spent weeks trying this and a lot of cash went down the drain. But its possible to make crystal clear masterfluid with distilled water, propylen glycol (from the vets) and some surfactant (basicly just soap but i dont remember which one doesnt cloud up...some car wash stuff) you can buy from the gookit guys. Just make sure the fluids are cold when mixing or you'll get a cloud. About 30% glycol is fine but thats for mathmos...trial and error. Good luck! And let me know if you find a solution for the wax which doesnt involve stinky, pricy, evaporating and leaching perc :-)

    I knew a guy who made a perc lamp which worked for some longer time...like two runs or so;-) theres a video in the tube and it looks very cool and transparent like but as I said...once or twice max..
