The crystal glasses have become milky due to a process called etching. Etching occurs when the surface of the glass is eroded by the combination of alkaline dishwashing detergents and hot water, which can create a cloudy or milky appearance on the glass. This can also happen when the glasses are washed in hard water, which contains high levels of minerals that can leave a film on the glass. To prevent this, it is important to use a gentle, non-abrasive detergent and avoid washing the glasses in very hot water. **

The crystal green-transparent-milky stripe you are describing could be a variety of minerals, but one possibility is fluorite. Fluorite is a colorful mineral that can range from green to purple, and it often has transparent or milky stripes running through it. It is commonly used in jewelry and as a decorative stone. Another possibility is apatite, which can also exhibit similar green and transparent milky qualities. Both minerals are known for their vibrant colors and unique crystal formations. **

A real crystal differs from an ideal crystal in several ways. Real crystals may contain impurities or defects in their atomic structure, which can affect their physical properties such as color, clarity, and hardness. Ideal crystals have a perfect, repeating atomic structure with no imperfections, while real crystals may have irregularities that make them unique. Additionally, real crystals may exhibit variations in their growth patterns and shapes, whereas ideal crystals would have uniform characteristics. **

Crystal violet lactone is colorless because its molecular structure is in a closed lactone form, which does not absorb visible light. When crystal violet lactone is exposed to an acidic environment, it undergoes a chemical reaction that opens up the lactone ring, forming the colored crystal violet dye. In this open form, the molecule is able to absorb certain wavelengths of light, giving it a violet color. Therefore, the color difference between crystal violet lactone and crystal violet is due to the structural change and resulting ability to absorb light in the visible spectrum. **

Tattoos can appear milky or cloudy during the healing process due to the formation of a thin layer of plasma, lymph, and excess ink on the skin's surface. This layer can give the tattoo a hazy or milky appearance until it naturally sloughs off as part of the healing process. It is important to follow proper aftercare instructions provided by the tattoo artist to ensure the tattoo heals properly and maintains its vibrancy. **

Crystal glass is a type of glass that contains lead oxide, which gives it a higher refractive index and greater sparkle than regular glass. It is known for its clarity, brilliance, and resonance when tapped. Crystal glass is often used to make high-quality glassware, such as wine glasses, decanters, and chandeliers, due to its luxurious appearance and fine craftsmanship. **

No, this is not a crystal. Crystals are solid materials with a regular repeating pattern of atoms or molecules, giving them a distinct geometric shape. This image does not show any such pattern or structure, so it is not a crystal. **
