~ Note ~ It is important to remember indigenous clays can contain lead;</div> <div> prior to using fired pieces functionally, you may want to test for lead content. </div> <div>  You can purchase lead test strips from you local clay distributor.</div> <bR> <div> ~ Materials Needed ~</div> <bR> <div> 1) 2 Five gallon buckets</div> <bR> <div> 2) 60 mesh screen to sieve with (window screen works fine)</div> <bR> <div> 3) You will need something to dry the clay in:</div> <div> Preferably an old pillow case or a piece of canvas or the leg of an old pair of jeans</div> <div> ~ Drying your clay on plastic will not allow the excess water to drain properly~</div> <bR> <div> 4) A place outdoors to dry</div> <bR> <bR> <div> ~ Let's Begin ~</div> <bR> <bR> <div> 1) Fill one of your five gallon buckets with your clay</div> <bR> <div> 2) Fill the second five gallon bucket 1/2 full of water</div> <bR> <div> 3) Gradually add the clay from your first bucket into the </div> <div> bucket with the water,</div> <div> You want to end with a very liquid clay/water mixture consistent with that of a watery clay slip.   Stir this mixture vigorously until well mixed</div> <div>  In this part of the process you are actually suspending </div> <div> the clay in the water.</div> <bR> <div> 4) Place the screen over the now empty clay bucket,</div> <div> gradually pour the clay/water mixture though the screen,</div> <div> sieving out all the excess debris, </div> <div> (Be careful not to break rocks and debris into your mixture)</div> <bR> <div> 5) Once you have the clay sieved, set aside and let sit overnight</div> <bR> <div> 6) The clay and water should separate.</div> <div>  The clay will settle on the bottom of the bucket and the water </div> <div> will be on the top</div> <div> Pour off excess water just to the top of the clay</div> <div> The top surface of the clay may have organic matter, if so,</div> <div> scrape off and sponge off excess water.</div> <bR> <div> 7)  Pour the clay into the pillow case, fold it over and push down,</div> <div> You will see excess water coming through the case (this is what you want). </div> <div> For best results leave the pillow case and clay on the ground to dry.</div> <div> The ground actually helps to pull the water out of the clay.</div> <div> At this point,  the rest of the drying process may take 2 or 3 days to reach </div> <div> a workable consistency.  Check periodically, continue leaving on the ground to dry.</div> <div> Your clay is ready when there is enough plasticity for forming and working</div> <bR> <div> 8)  Once workable, pull all of the clay out of the bag and <A HREF="id18.htm" TARGET="_top" TITLE="Wedging"><U>wedge</U></A></div> <bR> <div> 9) To test for plasticity roll out a coil from your clay and bend,</div> <div> if no severe cracking takes place, your clay has the right amount of plasticity</div> <bR> <div> The next step will be determining the type of clay you have </div> <div> and the
