[2025-10-01T06:42:26.369506] [PI reasoning] **Analyzing zinc phosphate cement**

I’m working on a multiple-choice question about the setting time for zinc phosphate cement, which is typically 4-7 minutes. The query asks which method does not prolong the setting time. Reflecting on dental material principles, I remember that increasing the powder-to-liquid ratio quickens the setting. They mention that adding powder gradually can prolong the time, as it reduces heat buildup. Conversely, prolonged mixing actually speeds up the reaction due to breakdown of zinc oxide. So, I must identify which method doesn't aid in extension.
