Bubbles in wax, when liquid density is lower than water

[Da9L]

Well the title probably says most of it ..

What i have experienced is that if you want to reduce bubbles inside the wax (bubbly wax) you can use glycerin. When using salt to change liquid density i often get bubbly wax as a result, but if i use PG, fog fluid or Glycerin instead i do not get bubbly wax.. This is, from my understanding, due to that salt decreases surface tension, and that makes bubbly wax..

This should be "no problem" do deal with.. Just use something other than salt to increase the liquids density.. But when working with lamps that has a density that is LOWER than water, what could be done? What can be used?

To decrease the density of the water i have been using 35% propylene alcohol, but vodka can actually be used too. But since the surface tension is also decreased with these liquids, what can be done?

Very cool, what's 'fog solution' and where do you get it?

I don't think the issue is with the water if you want to increase the surface tension - its more with the wax, could you try adding some glycol to the wax to make it slightly more thicker thus increasing its surface tension.

Another option is assuming that there is already surf in there - take some of the water out add some more but no surf thus decreasing the amount of surf.

Vision - fog solution is put into fog machines to create fog it is manly composed of glycol and DI water. you can get it from lighting supply companies and mobile DJ shops - just Google it and you will find.
