Common mistake
Misunderstanding Material Properties
Students often confuse the properties of glass with those of clay ceramics, thinking they have similar physical characteristics.
To fix this, students should study the specific properties of each material, noting that glass is typically more brittle and transparent, while clay ceramics are more porous and can be shaped before firing.
