Verified step by step guidance1
Understand that the question is about the physical appearance of polycarboxylate cement when mixed correctly in the laboratory.
Recall that polycarboxylate cement is a type of dental cement known for its specific texture and finish after proper mixing.
Consider the typical characteristics of correctly mixed polycarboxylate cement: it should not be sticky, grainy, or powdery.
Recognize that the correct appearance is described as 'glossy and smooth,' indicating a well-mixed, homogeneous material.
Conclude that the correct answer is 'Glossy and smooth' because this reflects the ideal consistency and finish of the cement after proper mixing.
