Dževad Delić preparing clay. Malešiči

RC interviewing Dževad Delić about milling clay. After letting the clay rest for a while, it will be put through the mill again to take out any rock impurities and make the clay "softer". Rolling the clay twice is considered sufficient, although more times would improve it further. In earlier times they used to "kiseli" (it is not clear what he means by this, but probably soacking and treading) the clay outside, but this machine makes the process quicker.
