Just looking if anyone has any ideas on how to keep gunge warm or how to warm it back up after it has been left to stand overnight?
Basically I want to mix the gunge a day (ideally two) before the day that I use it so that it has time to thicken / get slimy etc... However this is obviously going to make it go very cold, is there any way that I could either keep it warm whilst it is 'standing' or could possibly warm it back up a little bit just before I want to use it?
If it helps then I'm planning on using 80 litres...
If you can fit your container in the oven, sit it there. Don't turn it on, of course, but the oven will allow it to retain it's original heat longer. Possibly warm the oven up ahead of time then once it's cooled down to a comfortable level, place your container on a rack if there's room and let it sit there.
Needless to say, warming up cold gunge in the oven is probably not the best idea xD
