In food, titanium dioxide is often used as an artificial color additive. Tasha Stoiber, senior scientist at the consumer health nonprofit Environmental Working Group, says titanium dioxide can generally be thought of as a paint primer – it often goes on a hard-shelled candy like Skittles before the color is added to give it a uniform shine.
Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.
The assessment was conducted following a rigorous methodology and taking into consideration many thousands of studies that have become available since EFSA’s previous assessment in 2016, including new scientific evidence and data on nanoparticles.

Boat upholstery is not just about style; it needs to withstand a variety of challenging conditions. Marine environments expose fabrics to moisture, sunlight, salt, and wear over time. Therefore, the materials used for boat upholstery—such as vinyl, canvas, and outdoor fabrics—are designed to be both aesthetically pleasing and highly durable. In this context, the sewing machine you select must be capable of handling these heavy-duty fabrics effectively.
The presser foot holds the fabric against the machine’s feed dogs, assisting in its smooth movement as stitches are formed. The pressure exerted by the presser foot needs modification depending on the fabric’s thickness. Light fabrics require gentle pressure to avoid stretching or distortion, while robust fabrics might necessitate firmer pressure for efficient feed. Machines that allow for presser foot pressure adjustments allow users to customize this crucial point of fabric-machine interaction, ensuring optimal fabric feed and reduced sewing mishaps.
Exploring the Zigzag Embroidery Machine A Crafting Revolution
One of the most significant advantages of a multi needle quilting machine is its efficiency. Traditional quilting methods can be time-consuming, especially when it comes to stitching intricate patterns.
