Arena curling club - Freezer temp for rock storage
I curl at an club which converts hockey arena ice to curling ice for club play on a weekly basis. We store our rocks in freezers to keep them cool between curling sessions. What is the optimal temperature to store the rocks? Obviously, too hot and the rocks will be very slow. Is there a reason to keep them warmer than the desired ice surface temperature, around 24 degrees Fahrenheit? Is there an optimum?

The ideal way to store rocks is on the ice that you will play. So, you should measure the surface temperature of the ice in a few spots (center of each house, mid ice, hog line, and set the freezer temp to the coldest ice temperature you find. Rocks take a long time to change 1 degree, so if you leave them too warm, they will burn in somewhere on the ice.
My guess is the ice will be colder that you would like, because hockey players tend to like colder/firmer ice than curlers, so dotn set to the 24 degrees you want, set to the temp the arena has the ice at.

It is my understanding that the opposite is true...club/curling ice tends to be a few degrees colder than hockey ice because skaters want ice that's a bit softer (easier to skate on as blades can dig in) while for curling a harder/firmer surface is better as it's generally more level/playable and less prone to "damage."
As an arena curler, I find that clubs tend to be a lot colder than the hockey/arena ice I've played on, which would make sense if the ice is colder.

Thanks for the feedback. We have been setting the freezers at around 32 while the ice surface is around 25, sometimes warmer (footing gets quite slick). Unfortunately, the temperature control swings greatly from week to week based on the air temp in the arena, which varies greatly depending on how hot it gets outside and how much activity is in the arena that day. Sounds like we should try dropping the temperature of the freezers and see if it helps. Thanks!

The firmer the ice, the faster people can skate. Most hockey players want to be fast. Figure skaters want soft ice you can dig into. curlers like 24 degree ice. You should google how they make speed skating ice. it is fascinating and amazingly involved, almost installed like you would a tile floor.
I would guess 32 is way too warm to keep your rock. The ice, no matter what will be colder than 32. So that means that your rocks will 100% be guaranteed to burn into the ice, meaning they would be constantly be melting the ice the whole time that you are playing. Try 24, and see what happens if you dont have the ability to measure the ice. Also, if you measure teh ice, dont use an infrared thermometer, as they struggle with accurate ice measurement.

Interesting...I'll have to look into that. Thanks for the info!

The recommendation I received was to store the stones at 38-40 degrees. In a curling rink the stones stay somewhere between ice temp and air temp - around 40, and once you place them on the ice the bottom of the stones should cool to appropriate temp pretty quickly (10 minutes, ie. pebbling time).

If your rocks have ceramic insert running bands, they will chill fast. If they are granite, this is not true, and they will change temp very slowly.
But also consider the physics of cooling a rock. The easy thought it that when you sit a hot rock on ice, the cold chills the bottom of the rock. But the other thermodynamic action, is that the heat in teh rock is being sucked out of the rock via the running band. So the rock is basically a source with lots of heat (if stored at a higher temperature) and all of that heat will fight the cold from the ice to set the temperature of the running band. Until the heat well of the rock is empty, the running band will always be hotter than the temperature of the ice, adn thus slow and try to burn into the ice.
But you have an issue in teh freezer if you have any moisture. The moisture can condense on teh rock, and then it will freeze (like how walls in a freezer chest will eventually get thick with frost. If it does condense, and freeze, now you have a thin layer of frost or ice on teh rock, and you have to deal with that now. So one advantage of keeping the rocks at 33 degrees, is that there is no risk of frost or ice. So you will have to learn your situation to see what works best.

Very useful information for me, thanks dordle

As stored in an actual curling club, the rock upper area will be the air temp, which is about 40, but this does not matter at all. What matters is the running band of the rock, which is sitting on the ice. Most curling clubs will have ice at about 24F, so in theory you want to store your rocks at 24, or even 23 degrees. Never store the rocks above 24
You are right that temp will swing wildly at most rec hockey arenas, so here is the best plan.
Start by putting your freezer at 24 while you move in on the study. As you study temp, just look, do you see the rocks "melting" into the ice. In other words, once you put the rocks on eh tice and they sit for a few minutes, do you see rings left melted into the ice. If so, your temp is too high. Drop a degree or 2 and retry.
Part 2, Measure the ice temp over a week or so. Dont measure it after a wet zamboni flood as this gives you false data. Set your freezer at the lowest point you are seeing, such as 21 or 22. I would not go much below 21 or 22 regardless of anything else.
Last note, hockey ice has lots of issues. If you just go with 24, this is probably good enough if you dont do anything else, and then you are just left with the troubles of the hockey ice.

As long as the cold chain is not broken and there is no issue with the ice, you don't need to know the temperature of the freezer which is storing ice. Stickman boost can help you to increase the life of the ice. But it is not necessary. The best way to store ice is to use a commercial cooler ( https://www.ancasterfoodequipment.c...mercial-coolers ). They have better temperature control and a stronger insulation.

The game's core concept revolves around Snow Rider 3D mastering the art of sledding, requiring players to skillfully maneuver through a challenging terrain filled with rocks, trees, and various hazards.
