We took temperature readings during different periods of time after a certain number of cycles with this machine and that cooling effect was lost - not surprisingly because those calcined clay particles were crushed and unable to hold onto that water - so while initially we saw some benefits with the addition of the calcined clay at these levels and with this material, once we put it into a real-world situation, that cooling effect was lost and potential problems such as the clogging of the backing of the carpet when we see these calcined clay particles get crushed.
