Not the white stuff

[Biowraith]

I was wandering, is new Green Stuff quite soft, as my old stuff is very hard, and i cant remember if it started that way.

I have noticed that it can change in conistancy with age - but also differences in how you mix it up can lead to this (often as not one side of the bar is a little wider than the other

i usually make a 2:1 mix of blu tack to modellin putty. It becomes very moldable and in larger amounts

Add more yellow. The yellow makes it softer, blue makes it firmer when mixed, but of course this results in making it harder to shape hard edges at first. (hmmm unless I am reversing the two colors. . )

If you are not going to use a packet of greenstuff for a while, I suggest storing it in the freezer to prevent it going bad. Apparently over time it can loose consistency and 'go bad', eventually becoming unusable. Just make sure to clearly mark the container otherwise it might be mistaken for something else

Also, if you can, cut the two colors apart from each other. Wherever the two colors touch the chemical process WILL occur. So greenstuff left for a long time will begin to harden in that teeny area where the two colors touch. Always cut this away before mixing your greenstuff as well. I cut mine apart, wrap each in plastic wrap, place them in a ziplock bag and store them in the freezer. I know it is extreme, but a good craftsmen takes care of his tools. . .
