Yes, black crayons do contain color pigments. To understand this better, let's delve into how crayons are made and what gives them their colors. Crayons are primarily composed of two components: pigments and a binding agent, typically paraffin wax. Pigments are responsible for the color, while the wax acts as a binder, holding the pigment particles together. For black crayons, specific pigments such as carbon black or lamp black are used. These pigments are finely ground particles that absorb most wavelengths of visible light, giving the crayon its characteristic black appearance. The choice of pigment can affect the shade and quality of the black, with some brands opting for higher-quality pigments to produce deeper, richer blacks. Overall, black crayons, like all other crayons, rely on pigments to achieve their color.

Tinting Rust-Oleum EpoxyShield is not recommended by the manufacturer due to the formulation’s specific chemical properties. Altering it with colorants could compromise the product's integrity, adhesion, and durability. However, Rust-Oleum offers a variety of pre-tinted colors providing options without risking the product's effectiveness. Should you need a custom color, consulting with a professional to explore compatible products or surface coating options is advisable. Always ensure the chosen method aligns with your project's requirements for the best outcome.

Titanium belongs to the family of elements known as the transition metals, which are found in groups 3 through 12 on the periodic table. This group is characterized by its elements having partially filled d orbitals, which facilitates their ability to form a wide variety of compounds and complex ions. Titanium, specifically, is located in group 4 and is known for its remarkable strength, low density, high corrosion resistance, and ability to withstand extreme temperatures. These properties make titanium and its alloys widely used in aerospace, military, industrial, and even medical applications, where materials must perform reliably under harsh conditions. Its atomic number is 22, and it was discovered in 1791 by William Gregor. The discovery of titanium greatly impacted materials science, offering a metal that is both stronger than steel and less dense, making it an ideal choice for applications where weight and strength are critical.
