Can smoke fluid freeze?

Any liquid can freeze if it gets cold enough. The basic ingredient of smoke fluid seems to be either, kerosene, mineral oil, or propylene glycol.

All of these freeze at temperatures significantly lower than what you are likely to find in your garage.

SP smoke pellets freeze solid at room temperature and have not really damaged anything since 1947 unless too many pellets were put in before the previous ones were consumed.

Smoke fluid might get jellied at the very worst down to 40 below, and won't do any damage in jelly state.

Lets see it is 12;29AM and it is exactly zero degrees right now. For the fun of it I pout a full bottle outside. I will let you know when I wake up.

Fahrenheit or Celsius?

Fahrenheit two weeks ago we hit -15 tonight it is suppose to get to -5. Right now it is -1.

• -30C(-22F) is listed as the freezing point for mineral oil. Due to viscosity (how thick the fluid is, basically), however, it's lowest useful temperature is considered to be 10C (50F).
• Kerosene is thought to freeze at approximately -40 degrees Celsiu-74.2°F (-59°C)
• 1. -74.2°F (-59°C)

     Propylene glycol, Melting point

So short answer: yes, it can freeze, but if it gets to the temperatures where it WILL freeze, damaged trains will be the least of your worries.

Ok it is 8:00AM and I retrieved my full bottle of JT Mega-Steam "Fireplace" Smoke Fluid. Now I didn't go out and buy an expensive Technical thermometer. Nor did I do any type of control or advance planning.

I just did it the old fashion way and put it on a chair on the outside deck away form the side of the house.

At 0 degrees F this stuff will freeze as solid as a brick. Or at least at first glance that is what it looked like.

I was able to twist the dropper off the bottle with no problems. That is when I found out it is not in a liquid form but a soft jelled form of substance.

Lab note: This jelled substance is quickly turning back into a liquid form after only being in the warn house less than 5 mins.

Next test after thawing is will it smoke?

Ok I having a little fun but I had nothing better to do over a darn cold weekend.

After it thaws out make sure you shake the bottle.

Awesome!  I thought Lee Willis might beat you to the test.  Time to share wealth!
