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.
From Wikipedia, the free encyclopedia. Lager (German: storeroom or warehouse) is a type of beer that is conditioned at low temperatures, normally in cold storage at the brewery, before being delivered to the consumer.It may be pale, golden, amber, or dark.hile it is possible to use lager yeast in a warm fermentation process such as with American Steam beer, the lack of a cold storage maturation phase precludes such beer from being classified as lager beer.
