Triple Tray Impressions
Stalagmite® (using the Articulated Triple Tray System)
Repositioning the opposing model:
Prepare a thin mix of stone. Pour enough
stone into the Opposing_Base to allow enough
stone to overflow once the opposing model
is lowered. Lower the models until the hinge-
stop-rods just barely make contact.
Do not push down on the front of the
RTP Base after the hinge-stop-rod
has made contact, as this will cause the base
to spring back and take it out of compression
with the stone, which can lead to voids. If this
happens, tap on the sides of the Opposing
Base to re-settle the stone. It helps to let the
bottom of the opposing model soak in water a few seconds before lowering into position.
Remove sticky wax and clean models.
