Without an analyzer, a simple way to sort zinc and lead is to check their hardness. Use a knife to cut — or side cutters to squeeze — the material. If it is soft it is lead; if it is hard it is zinc.

Cut glass and lead crystal are both made from glass, but lead crystal contains an extra material that enhances the brilliance of the glass. It helps to know how to tell the difference because lead glass is usually of higher value than cut glass, and requires a bit more attention when cleaning.

The main indicating factor of the differences between brass and bronze is that bronze will have a much redder color hue than brass would. Brass will look more yellowish due to its higher zinc content. Brass is worth more money due to it being made up almost entirely of copper, which is worth more than zinc.

Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150°C. It is a reasonable conductor of electricity. The density of zinc is 7.140 g/mL, which means the metal will sink in water and is relatively heavy.

The main difference between white, yellow, and even rose gold is simply the metal mixture that's used to make them. ... White gold has more nickel and zinc, while yellow gold contains more copper. However, it's actually the karat number that you should be looking at if you're concerned about the presence of pure gold.

Zinc alloy is safe to make jewelry because it is lead-free, and the lead is the toxic substance that makes most jewelry unsafe to wear. ... Manufacturers rarely use zinc in its pure form, but instead, they add 55% or more of copper to it, to make brass, a common zinc alloy used in making various pieces of jewelry.

Standard iron consists entirely of the metal element iron, whereas galvanized iron has an added layer of zinc to it. When iron is galvanized, it's submerged in a bath of liquid zinc. The zinc is heated so that it changes from a solid state to a liquid state.

Magnesium alloys. One of the main differences between magnesium and zinc alloys is that zinc and zinc-aluminum alloys require lower pressure and temperatures for casting. Because of a lower casting temperature, zinc provides a much longer die life than magnesium, which can help reduce production costs.
