2/20/2024 0 Comments Diy low lying fog juiceGlycols, glycerine, and mineral oil can all leave an oily residue, resulting in slick or sometimes slightly sticky surfaces. Also, this is a danger with homemade fog juice used in commercial machines. This is one of the major problems with homemade smoke machines - they may operate at a temperature that is incompatible with the substances being used. Glycols can undergo heat denaturation into highly toxic substances, such as formaldehyde. Coolers can be used if low-lying fog is desired.Ĭhanging the mixture or conditions of dispersion of atomized glycols can result in many special effects that are difficult to achieve with other simulated smokes. This type of fog is heated and will rise or disperse at a higher level than dry ice or liquid nitrogen fog. Using a homemade fog mixture in a commercial machine will almost certainly void the warranty, possibly damage the machine, and possibly pose a fire and/or health hazard. Distilled water is only necessary if a heat exchanger or other tubing is used in the system. The lower the percentage of organic, the less expensive the fog juice, but the fog will be lighter and will not last as long. If it does, likely causes are too high of an operating temperature or too much glycerine/glycol/mineral oil in the mixture. The resulting smoke should not smell 'burnt'. (I can't vouche for the safety of using mineral oil for fog juice)ġ0% distilled water: 90% propylene glycol (dense fog)Ĥ0% distilled water: 60% propylene glycol (quick dissipating)Ħ0% water: 40% propylene glycol (very quick dissipation)ģ0% distilled water: 35% dipropylene glycol: 35% triethylene glycol (long-lasting fog)ģ0% distilled water: 70% dipropylene glycol (dense fog) Unscented mineral oil (baby oil), with or without water (glycerine creates a 'haze' at concentrations of 15% or less and more of a fog or smoke at concentrations higher than 15%) Some homemade recipes for fog juice are:ġ5%-35% food grade glycerine to 1 quart distilled waterġ25 ml glycerine to 1 liter distilled water See the reference bar to the right of this article for Material Safety Data Sheets on some example types. There are a variety of mixtures that may be used. The glycols are heated and forced into the atmosphere under pressure to create a fog or haze. Many commercial smoke machines use 'fog juice' that consists of glycols, glycerine, and/or mineral oil, with varying amounts of distilled water.
