Most types of glass aren't designed for hot drinks. When one part of the glass is suddenly heated up other parts might not be, the stress put on the brittle glass causes it to crack or shatter possibly spraying people near by in hot liquid.
First, the term for this is called "Thermal Downshock."
What happens is, the cooled surface shrinks in comparison to the glass inside, and the tension makes the glass break.
Abrasions, chips, and knife scores can intensify the breakage.
Thermal Downshock can also happen if you put a hot glass dish on a cold surface (granite countertop, etc). So always put the dish on a cooling rack, cooling pads, trivets, or potholders. If you have a gas stove, you can put the dish on the burner grates and it will be safe.
The glass can break because of the thermal dilatation.
The hot liquid could crack a cold glass.
Liquids that are spilled or condense onto the balance can dry there, throwing the balance off until it is re-zeroed or cleaned. The liquid residue can also become attached to containers when samples are weighed.
You should never look directly at a solar eclipse as it will damage your eyes. Look at it wearing very dark glasses or indirectly in a reflection in water
Absolutely not ! NEVER look directly at the sun - even through tinted glasses ! The best way - create a 'pinhole' camera - and view the reflection.
Doc (in the Walt Disney movie). In the original fairy tale, the dwarves did not even have names, never mind glasses; those were all Disney inventions for the 1937 animated film.
Methyl alcohol, also known as methanol, should never be used medicinally because it is highly toxic and can cause severe damage to the nervous system, liver, and other organs. Ingesting or using methyl alcohol internally can lead to blindness, respiratory distress, and even death. It is not suitable for medical use and should not be consumed or used as a substitute for ethanol (drinking alcohol).
Because the glass shatters
Rapid temperature changes can cause glass to crack. For the same reason you should never wash a hot glass with cold water.
you can if you put a spoon it the glass first before pouring in the hot liquid, otherwise the glass might crack
Moisture can be damaging for the balances, especially the electronic balance. Therefore, liquids should never be poured in the near vicinity of a balance.
They should be.
If your family is drinking it, you should never guessabout that ! Take a sample to a lab and get it tested so you KNOW how clean (or not) it is.If your family is drinking it, you should never guess about that !Take a sample to a lab and get it tested so you KNOW how clean (or not) it is.
Never
no not at all you should never do that!!
No you have to purchase the glasses.
Normal glasses are never a subsitute for safety glasses because they are not rated to take hard impacts and blind you if break from an impact.
It likely because he doesn't need glasses them. :) More likely is that that was what was the style when he was created and you should never change a cultural icon. == ==
yes never say never does have glasses if you buy the package i don't know if you get them when you just buy the ticket
