To empty the ink well of an Epson R300 printer, you'll typically need to access the waste ink pads located at the printer's base, where the waste ink from cleaning cycles is absorbed. First, disconnect the printer and carefully open the printer casing to locate these pads. Due to potential mess and the precise nature of this task, wearing gloves is advised. Gently remove the ink-soaked pads and replace them with new ones or clean them using water until the water runs clear, then allow them to dry completely before reinserting. After the waste ink pads are serviced, you may need to reset the printer's waste ink counter. This often requires a software tool specific to Epson printers, available from third-party providers, as Epson does not officially support resetting the waste ink counter. Be cautious, as improper handling could damage the printer or affect its functionality.

To seal Distress Oxide Ink, one effective method involves applying a clear, water-resistant sealant such as a spray fixative or a clear acrylic sealer after your ink has thoroughly dried. This is essential because Distress Oxide Inks are water-reactive, even after drying, which can lead to smudging if not properly sealed. Ensure your work surface is covered and work in a well-ventilated area when using aerosol sealants. Spray a light coat over your artwork, allowing it to dry completely before adding additional coats if necessary. For an alternative approach, use a brush-on varnish for more control over the application, being cautious to apply it gently to avoid reactivating the ink. Testing the sealer on a scrap piece beforehand is advised to ensure it doesn't react undesirably with the ink.

The INCI name for Titanium Dioxide is exactly that: "Titanium Dioxide." In cosmetics and skincare products, it serves as a pigment, sunscreen agent, and provides coverage or whitening effects. Being a naturally occurring mineral, Titanium Dioxide is found in various mineral deposits around the world and is widely appreciated for its high refractive index, meaning it is extremely effective at scattering visible light. This property makes it an excellent choice for use in sunscreens, where it acts as a physical blocker to protect the skin from UVA and UVB radiation. Additionally, in makeup products, it helps to achieve a matte finish and increases opacity due to its high covering ability. It's widely regarded as safe for use in cosmetic products, though there has been some debate about its use in nanoparticle form. However, most regulatory bodies, including the FDA and the European Commission, consider it safe for use in cosmetics, including sunscreens.
