Tips: How to soften your hard or crumb clays

Tips for today: 

I was experimenting earlier, making and practicing Mokume Gane; then i have some hard clays that really not easy to conditions, i wonder and think if this might work to make my clay soft and easy to knead. I don't wanna use liquid softening for clays coz it's getting sticky and messy.

So i do tried it and it works. What did I do?
I just cut some hard clays then i blower it (hot) yes i did use hair blower to make my clay soft in about seconds or minutes i guess, all you need is to check or touch the clay if it's already softening. And yeah it really works for me. 

Try it and don't be afraid. :)
Good day!
