The primary component of pot metal is zinc, but often the caster adds other metals to the mix to strengthen the cast part, improve flow of the molten metal, or to reduce cost. With a low melting point of 419 Â°C (786 Â°F), zinc is often alloyed with other metals including lead, tin, aluminium, and copper.
Although beer has a lower freezing point than water, it will freeze if left in a freezer for too long. The exact length of time varies depending on the beer.A frozen beer can sometimes be saved, but it usually isn't something you'd want to drink as it's often flat. However, all is not lost.he actual freezing point varies depending on the beer's content. Initially, some of the water freezes out of the solution. This is fractional freezing and is used in creating eisbock, a high-alcohol beer. However, be aware that as the water freezes, it expands; this can force the cap off a bottle.
Beer freezes at the temp of your freezer (about 0 F to 30 F). Pure ethanol (alcohol) freezes at about -176 F. The stronger the booze, the colder it has to be to freeze. Beer is fairly weak, so it doesn't have as low a freezing point as like vodka, rum or whiskey does. All alcoholic beverages will freeze somewhere in the temperature range of -176 F to 32 F. Just so you know, home freezers get no where close to cold enough to freeze pure ethanol. Everclear, which is about 190 proof (95% alcohol) will never freeze in your home freezer.
