Glass can become brittle in extreme cold, and it may crack or shatter, posing a safety risk and compromising your home's security and insulation. If you notice cracks or broken glass, prioritize window repair or replacement. Opt for tempered or laminated glass, which is more resistant to shattering.
Guard Your Glasses from the Elements
Extreme temperature changes can also cause the frames to warp or the lenses to crack. Extreme cold causes the materials your glasses are made of to become more brittle.
So it's important to keep your glasses in a protected, appropriate space during extreme cold. Leaving eyeglasses in a cold car can cause the lenses to crack or become brittle, according to Web Eye Care.
Glass bottles and jars are usually not affected by ambient, refrigeration, or warm temperatures. However, high heat (>300°F) and excessive thermal variations can cause glass to shatter or break.
For a start, the answer to the first question we mentioned is, “Yes, glass can break in the winter.” If a pane of glass is very cold or frozen, it will be unlikely to break, but easier to break than normal.
Can I put glass in the freezer? Only if it says freezer-safe (usually tempered glass). Otherwise, it can crack and that's no fun. Also make sure to remember that liquids expand, and glass has no wiggle room, so if you're freezing in a freezer-safe glass container, you still want to leave a little room at the top.
Glassware
It turns out that glass can become extremely brittle and easily breakable if left in freezing temperatures. This goes double for thin glass, like a coffee carafe or flower vase.
Soda glass and borosilicate glass are generally used below 500°C, Silicon is used below 600°C, and glass ceramics and glazed porcelain are used below 1000°C.
1200°F Draping – glass softens enough to bend over a mold. 1250°F Slumping – glass softens enough to bend into a mold.
It has been estimated that for every 1 degree difference in temperature between edge and centre of glass, increases the stress in the glass 0.62MPa. Given that temperature differences can easily be in the order of 20 to 30 degrees, a stress of 12 to 19MPa can be generated which is enough to cause a crack.
Glass does not break solely because of severely high or low temperatures. It is extreme temperature changes that cause glass to break. When the temperature of glass rapidly changes, some spots become cold or hot before others. This causes instability in areas with cracks or inclusions.

Glasses. According to Webeyecare.com, exposing prescription glasses to extreme cold can cause the lenses to expand and contract. The company also said frames are likely to warp in cold weather, especially if they're plastic.
Single-pane units do not have air pockets, thus allowing cold air and heat to pass through the glass more readily.
Contacts can freeze if the temperature of the solution they're stored in reaches about 5° Fahrenheit. If the packaging is intact, you can leave the lenses and solution out at room temperature for a few hours, and they'll thaw out.
Tempered glass usually comes in two varieties: annealed and heat-strengthened. Annealed can withstand temperatures up to 250°C (482°F), while heat-strengthened ones have a maximum temperature rating of 350°C (662°F).
glass systems are exposed to sunlight and other heat sources, one area of a glass pane becomes hotter than its adjacent areas. The temperature variation in a glass pane leads to thermal stress and increases the risk of glass breakage, as displayed in Figure 2a [44].
Slumping temperatures are typically between 1200 to 1300 degrees Fahrenheit. The glass will begin softening and turn glossy when the temperature nears 1100 degrees Fahrenheit and will start slumping as it approaches 1200 degrees Fahrenheit.
Standard glass cannot be used in the oven because it's unable to resist heat and begins to break at 302-392 degrees F (150-200°C). The intense temperature of an oven will cause the ordinary glass to crack.
Heat-resistant glass is a widely used glass type that is able to retain its shape in temperatures up to approximately 932°F (500°C) without breaking. Heat-resistant glass-ceramic materials are capable of withstanding temperatures up to approximately 1,800°F (1,000°C).
Glass becomes malleable at temperatures lower than its melting point, typically between 500°C and 800°C (932°F and 1472°F), depending on its composition. This range is where glass transitions from a rigid, solid state into a more workable, plastic state, allowing it to be shaped or formed.
When exposed to extreme cold, glass contracts, creating tension within the material. If the temperature disparity between the inside and outside of the glass is significant, this stress can exceed the glass's strength, causing it to crack.
Yes, you can definitely put glasses in the freezer. In reality, glass has no freezing point. It's solid and for that reason, technically can't be frozen. Still, if you want to chill a glass for your cocktail, a temperature of 32°F/0°C, or even a little colder should be enough.
