It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.  

Applications Across Different Fields

Moreover, the tableau has emerged as a powerful tool in activism and social commentary. Artists and activists have used staged tableaux to highlight social issues, drawing attention to injustices and sparking conversations around topics such as race, gender, and inequality. For example, in response to police brutality and systemic racism, performance artists have created striking tableaux that encapsulate the pain and resilience of marginalized communities. These artistic expressions not only evoke empathy but also challenge audiences to confront uncomfortable truths about society.
