Glass ionomer is mixed with an agate spatula because the agate spatula is non-reactive and does not introduce any contaminants that could interfere with the setting reaction of the glass ionomer. This ensures that the material sets properly and maintains its desired properties. Additionally, the smooth surface of the agate spatula helps in achieving a homogeneous mix without introducing air bubbles.

Why glass ionomer cement mixed with agate spatula on mixing pad?
Mixing glass ionomer cement with an agate spatula on a mixing pad helps prevent contamination of the cement from metal ions that could interfere with the setting reaction. Glass ionomer cements are sensitive to contamination, so using non-metallic instruments like an agate spatula and mixing on a pad that won't introduce metal ions ensures the material sets properly and bonds effectively to the tooth structure.
Why gic colour changes when mixed with steel spatula?
The color change observed when mixing GIC with a steel spatula is due to a chemical reaction between the glass ionomer cement (GIC) and the steel spatula. The metal ions from the spatula can react with the components of the GIC, causing a discoloration or a gray streaking effect. This reaction can compromise the setting properties and aesthetics of the GIC mixture. It is recommended to use non-metallic instruments when handling GIC to avoid such color changes.
Why glass ionomer cement not mixed on glass slab?
Glass ionomer cement should not be mixed on a glass slab because the ions present in the cement can react with the glass slab, leading to contamination and affecting the setting reaction of the cement. This can compromise the physical properties and performance of the cement. It is recommended to use a disposable mixing pad or a mixing paper to prevent any unwanted reactions and ensure the proper setting of the glass ionomer cement.
What makes red glass red?
Red glass is made by adding metal oxides, such as selenium, to the glass mixture during production. These oxides absorb certain wavelengths of light, allowing only red light to pass through the glass and giving it a red hue.
What happens when you mix glass and rubber?
When glass and rubber are mixed together, they do not chemically bond. Glass and rubber have different properties and do not typically adhere to each other. The resulting mixture would likely separate into distinct glass and rubber components.
