Spread a small amount of moisturiser on your work surface, tip the clay out and knead until cold (it will be hot to start with so be very careful) - fill your pan/bowl with hot water to soak.
**TOP TIP - I found that even though I had used the moisturiser the clay still stuck to my work surface so I rubbed a little moisturiser on the palms of my hands and pressed & kneaded the clay just between the palms of my hands (it didn't stick). I kneaded it in this way for about 20 minutes until it had gone cold - TOP TIP**
