The price list for lithopone pigment in China is influenced by several factors. Firstly, the availability and cost of raw materials, zinc sulfide and barium sulfate, have a direct impact on the final product pricing. Fluctuations in the global market for these minerals can lead to changes in the lithopone pigment prices. Secondly, production capacity and efficiency of Chinese manufacturers also play a crucial role. A high production capacity often results in more competitive pricing due to economies of scale.

Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

  • Presser feet act as the main point of contact between the machine and the fabric. For light fabrics, specialized feet can make a world of difference. A walking foot, for instance, ensures even fabric feed from both top and bottom, reducing puckering. A Teflon or roller foot can prevent fabrics like silk or satin from getting stuck. A narrow straight stitch foot can offer more precision when sewing straight seams on delicate fabrics.

  • Maintenance is also an important consideration when investing in a long arm upholstery sewing machine. Regular cleaning and oiling of the machine's moving parts will help ensure smooth operation and prolong its lifespan. Additionally, it is recommended to have the machine serviced by a professional technician annually to address any potential issues and keep it running smoothly.

  • With different stitch options available, sergers can add decorative elements to your sewing projects. You can use contrasting thread colors or specialty threads to create eye-catching details along seams or edges. This adds a unique touch to your work, allowing you to personalize every item you make.

This method is particularly popular in the fashion industry, especially in creating garments that require durability and a stylish finish.


  • Automatic bag closer machines are designed to seal bags of various materials, including those used for food, chemicals, textiles, and more. By automating the bag closing process, manufacturers can significantly increase their output while maintaining a high standard of quality. These machines can handle different types of closures, such as heat sealing, ultrasonic sealing, and stitching, making them versatile solutions that can be adapted to various products and industries.


  • Fibonacci sequences are a fascinating topic in mathematics that have intrigued scholars and mathematicians for centuries. The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones. The sequence starts with 0 and 1, and each subsequent number is the sum of the two numbers that came before it.
  • Replace the needle regularly to prevent skipped stitches and fabric damage.

  • Moreover, these machines often come equipped with advanced features such as automatic thread cutting, tension adjustments, and programmable stitch patterns. Such technology minimizes errors and reduces the need for manual adjustments, allowing quilters to focus on creativity instead of troubleshooting.



  • The technological evolution of threaders has also played an essential role in making sewing accessible to everyone. Modern designs include automatic needle threaders that take the effort out of the process altogether. These devices often feature buttons that, when pressed, quickly accomplish the task of threading without the need for painstaking manual effort. This is particularly advantageous for individuals with physical limitations or those who sew in large volumes, such as in the fashion industry or for charitable sewing projects.
