Stalagmite      Pouring Standard Impressions (using the Pouring Jig)

Pouring Arch Impressions:


Remove the impression from the plaster index. Pour stone to top of impression and return it to the plaster index (be careful not to get any stone on areas of the impression that would cause conflict with the plaster index). Add a small amount of stone around the pins of the RTP_Base. Tap the sides of the base with a spatula or small instrument to settle the stone around the die pins and small index pins on die surface of the plastic base. This part of the procedure is very important so as not to trap air and to eliminate voids. Trim away any excess stone around the inside and outside of the the arch.


Add additional stone to the impression and enough to cover the pins on the RTP_Base. The extra stone is necessary to insure that the stone is kept in compression and at the same time supplying enough material to fill voids when the base is lowered into position and excess stone is squeezed out around the edges.

Weighing the stone and measuring the water for each mix will help guarantee quality and consistency. Working with the same consistency each time is very important, as you will become proficient more quickly. You do not want an overly runny mix at this point.
