Topic Subject : RE: speeding up setting time of plaster

Terra Alba ('white earth' is the Latin translation used from ancient Roman
times until this day). Is still the best material to speed set time of any
gypsum plaster. Unlike salt it does not weaken the plaster as it is made
from gypsum.

Warmest regards

Re: speeding up setting time of plaster:--
Hi Claire

As others have said, a dash of salt in the mix speeds it up (best to
experiment to work out how much. I just do things by the pinch or
handful, never measure anything).
Or, as Philip said (I think) flakes of dry plaster in the mix or even
better a small amount of just setting (starting to turn to about wet
sand consistency) plaster just at the bottom of your mixing vessel will
act as a catalyst and make the rest turn faster.
Or use warm water, which is a simple and fast way of increasing setting
time.
Dental plaster isn't expensive though, so maybe it's worth investing in
some to have a go with.
