Features

• These high form porcelain crucibles have a capacity of 50ml. They are uniform, dense, and have stable mechanical strength and little permeability. When properly used, the glazed pieces withstand temperatures of 1050degC and the unglazed pieces 1350degC.
• Heating and Combustion Experiments: Use crucibles to heat small amounts of solids, such as salt or metal powders, to observe chemical changes during high-temperature reactions.
• Dehydration Reactions: Demonstrate water loss in hydrated salts like copper sulfate by heating them until they turn from blue to white.
• Ash Content Analysis: Burn organic materials (such as leaves or paper) to show how only inorganic ash remains after combustion.
• Melting Point Demonstrations: Test the melting points of small metal samples or other materials.
