**Step 6:** The number of press pellets used for each restoration is relevant to the weight of the full contour waxup minus the weight of the opaqued copings. After each measurement was accurately noted, I knew exactly how many pellets to use for the four anterior crowns. (Most manufacturers will inform you of the correct relationship between wax weight and number of press pellets.)
**Step 7:** After burnout at 900°C for 40 minutes, I pressed the crowns at 940°C and allowed them to cool down to room temperature. I opened the mold by first drawing a line at the height of the plunger, marked a horizontal line at the correct height and used a diamond separating disc to cut along the line. Then I used a knife along the vertical edges to separate the mold.
**Step 10:** To obtain a natural glaze, I polished the surface with fine conical diamonds, then used a non-contaminating white silicone rubber point and finished with a leather wheel saturated with white tin oxide. After the surface appeared nice and smooth, I ran the crowns through a glaze bake with a minimum amount of stain liquid applied.
