Seconded.
I never thought of it before, but the mixing bucket I have is pretty big, so I've been making more than I need.
I don't want to know what would happen if I used warm water. Winter, numb hands and I still only had five minutes working time.
Thanks Ed, Thanks everyone.

Re: How can I slow down the setting time of plaster.
I am no expert on this so you may want to look this up elsewhere. I bought a book from a company called 'Castcraft' a while ago and they say to slow down plaster add Borax (5% by weight) to the dry plaster. They also say to add ordinary baking flour (white flour). They say to mix the plaster as usual then add the flour until the plaster becomes thick as paste. They say you can then shape the plaster for hours. They say it will then take 24 hours to harden completely and will be full strength then.
Like I said, I'm no expert and haven't had to try this so you may want to experiment on a small batch just to see.
