The document asks about identifying the origin of a boulder formation found in a kiln. It seeks advice on what physical and chemical properties to examine in the boulder's remains to determine if it formed inside the kiln or was introduced from the inlet coating. It also describes how the boulder broke into large pieces upon removal but then fully disintegrated into a powder once cooled, and asks what conclusions can be drawn from this phenomenon of the boulder holding together when hot but crumbling when cold.

1. Boulder formation.
Sir,
By looking at the Boulder in Physicaland chemicalform is it
possible to make out whether the boulder that was formed is
formed in the Kiln itself due to some favourable reasons or it was
formed from the coating from the kiln Inlet. What to look for in the
chemical results ofboulderthathelps to identify its origin of
boulder formation.
The boulderwas taken out and broken to Big Pieces.It was kept
aside and as it started cooling it all disintegrated into Powder form.
Why is this so? What to conclude from this Phenomenon? TheBall
inside kiln not breaking butonce out and become coolbecoming
powder allby itself. Hope somebody will throw light on this.
