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.

Carbon steel is becoming a chefs' favorite choice in the kitchen. These pans heat up quickly and evenly. This material is an excellent choice for non-toxic cookware. It is lighter and less clunky than the heavy cast iron. Carbon steel actually contains more iron than those cast iron skillets. This type of material is versatile, and you can use it for all kinds of cooking.
While saute pans are designed to retain moisture and help steam vegetables, French skillets are better suited for frying and cooking dishes that require larger surface areas.
Durability and Longevity: Big black cast iron skillets are built to last a lifetime and beyond. With proper care and maintenance, they become seasoned over time, developing a natural non-stick surface that improves with use.
In conclusion, while French skillets and frying pans are made of stainless steel, the difference in their design lies in the height of their sides.

A skillet, sometimes referred to as a frying pan or a frypan, is a shallow pan with slanted sides. Skillets are commonly used to stir-fry or sauté, which refers to a method of cooking in which ingredients are cooked quickly in a small amount of oil or fat, often over relatively high heat. The slanted sides make it easier to stir, flip, and toss ingredients in the pan so that everything is cooked quickly and evenly. After all, the word “sauté” in French literally means to “jump,” just like vegetables “jump” in a skillet when sautéed or stir-fried.But a skillet has other uses, too, and it is considered to be one of the most versatile pieces of cookware in the kitchen. For example, a stainless steel skillet is great for searing meat, chicken, or fish, or for making simple pasta or pan sauces. Simply put, a skillet is one of the most versatile pieces of cookware in the kitchen.
