What is the safest method for assembling sheets of brass sculptures in a classroom setting?

Soldering is often considered the safest method for assembling sheets of brass sculptures in a classroom setting because it involves lower temperatures compared to welding, which reduces the risk of burns or fire hazards in a classroom filled with students. Additionally, soldering typically uses non-toxic materials that are more appropriate for an educational environment.

This method allows for strong joints while being manageable for students to learn and apply under supervised conditions. It requires minimal equipment and tools, making it easier to control the process and ensure safety. The use of solder also does not emit harmful fumes in the same way welding can, which is an important consideration in confined classroom spaces.

While gluing and screwing may also be options, they don't provide the same strength and permanence of connection as soldering does when dealing with metals. Gluing may not effectively bond the brass sheets in a way that withstands stress, and screwing may require drilling, which introduces potential hazards such as sharp edges or metal shavings.
