I've always done this, too. Those of you who want to use local clay should
keep in mind that very little naturally occuring clay will be adequate without
additions of something. Even Maria Martinez, when she gathered her clay, added
to it (see the PBS video). Clay almost always needs something added to either
make it shrink less, more plastic, etc. Also, test fire some tiles to check for
shrinkage.
