I have been waiting to reply on this so I could give you more than just my opinion. This comes from the CND lab. He did go from the standpoint of the Shellac being frozen as we have had some people leaving it in their cars, but I thought you might want some of the information.
All Shellac (basecoat, colors, and topcoats) are flammable. Strictly speaking, they should not be near or in contact with opened flame, electrical wires, sparks, static sources, microwave, etc... During the process of warming/thawing, caps should be tightened well to prevent spills and also not having contaminants get into the bottles. Beyond those general guidelines, if the users still ask for more detailed instructions, then here are some tips: 1. Don't have Shellac frozen from the first place. Shellac, like any other products, is best kept and performed in around room temperatures (20-25°C or 68-77°F). If they have to be left in uncontrolled room (or car) for an extended period of time, put them in some isolating container (igloo box for example). Isolating container can only extend the time it takes but not prevent freezing totally. 2. If a bottle of Shellac has already frozen. Thawing, if done right, will bring frozen Shellac to its full performance. The thaw time is a function of the temperature of the bottle, the temperature of the warming media, and the area of contact (of the bottle with the warming media.) The higher the temperature, the more the area of contact, the faster thawing is. Don't over heat, because you will then have to spend time cooling it down to room temperature. Over heating for a extended period of time will also have negative effect on the shelf life of the product. The best thing to do is to plan ahead of time, don't wait until the last minute. If planned more than 24 hrs ahead of time, leaving the frozen bottles (separately, apart from each other) in a cozy room is all that it would take. In case there was no plan in advance, and the frozen bottle needs to be used rather urgently: a. Tighten the cap. The cap may feel tight because the product is frozen inside, wrap around between the bottle neck and the cap with "electrical tape" (or sometimes called "black tape" that can be bought from Home Depot or grocery stores. b. Put the bottle in plastic bag (ziploc), seal the bag without leaving too much air in it. The air inside the bag decrease the area of heat contact. c. Put the sealed bag with bottle inside in a: c.1. Warm-hot (at the temperature range that people can drink or at least can sip, 40-60°C (104-140°F)) water bowl/cup. c. 2. Electrical blanket (or heating pad) that is set at temperature in the range of 35-50°C (95-122°F). It takes about 5 to 30 minutes depending on your setting. If water is used, it is a good idea to give the bottle one extra plastic bag. At the end of thawing, tap dry the outside of each bag before opening it. This way, there will be minimal amount of moisture stuck on the bottle. Wipe excess water/moisture off the bottle before opening it. Even though it sounds like the use of warm water is more complicated than the use of electrical blanket, water will less likely over heat, because the water is cooled off by the environment over time. On the other hand, the electrical blanket or heating pad has high temperature all the time. If the bottle is not taken out soon enough, over heating may occur and more time is needed to cool the bottle down to room temperature. c.3. a warm environment that relates to body heat (bra, leg, etc...). There is nothing wrong with it, as long as it does not cause freezing effects on "the body part", and as long as there is no product leaking out from the bottle. d. Shake the bottle well before use.
