agroperlite is agricultural perlite (I think) which is often used for seedlings. It can be used in bonsai soils, but is more recently being taken over by cheaper alternatives. If you plan on using perlite as an ingredient, be careful to ensure that either the other ingredients are virtually non-absorbent, or that the perlite forms no more than 20% of the total mix, as it is very absorbent. It is also very unstable (breaks up easily) so it may not be very preferable.
As for the other thing... it may be moler clay? Moler clay is what I use as a 'soil' as it's free draining, absorbent and has sharp edges. If you plan on using it, make sure that it IS in fact moler clay, otherwise there could be a lot of fatalities.
I love links, so:
