<p>I continue the discussion with some examples of recent sandblasting results.</p>
<p>In the picture below you see a bisque fired pot with - in relief- a triangle. The blasting was done on bone dry clay with the bottom feed gun using quartz sand . The masking was done with wax emulsion. Clearly the blasting was aggressive: the edges are rounded and the whole masking was damaged. …</p>

<p>On the following picture one can see what happens if the Aluminum oxide in the air eraser is not completely dry:</p>
<p>Some irregular pitting occurred . I left it like that, no masking, in the idea it might become a decorative texture.</p>
<p>Here also the blasting was done on bone dry clay before bisque.</p>

<p>Before pursuing this technique I also will have to obtain some rubber cement.</p>

<p>Hi Larry,</p>
<p>No, this sand often used for masonry is much too coarse for the air eraser, unless you find a quality that's fine enough. Unfortunately, Paasche nor Badger give the mesh size, but on sight it must be 250-300 mesh.<br></br> <br></br> <cite>Lawrence Weathers said:</cite></p>
