T5 is marketed as a filtration aid. Will it behave as a neutral version of T41 (minus carbon), sort of. T5 is the most simple and straight forward bleaching clay. We sell it as a filtration aid because it has been designed to filter faster than normal clays and less prone to clogging, while still having the bleaching clay absorptive properties.
If you want to play with a neutral clay that acts more like T41 then I would suggest Summit Research’s Achromatizing Clay. It is similar to T5 but much more refined and lower in intercalated moisture.
