Here is Pure-flo’s product list.

It looks like Oil Dri uses the brand name Pure-flo to market their Attapulgite products to edible oil makers.

Pure-flo offers three product series, Natural, Supreme and Perform.

It looks like all three series come from their Ochlocknee, GA mine. Based on info on the Agsorb website (Agsorb is another subsidiary of Oil Dri) this mine is a source of Attapulgite bentonite clay.

As you can see in the chart, the ph decreases as you go across from natural to supreme to perform.

Pure-flo recommends the lower ph (higher activation) clays for more difficult to bleach oils. The perform series has the highest level of activation.

I have always gotten the best CRC results with T41. However, since the supply of it has run out for now and its characteristics have possibly changed permanently, I have renewed interest in trying other acid activated clays.

T41 is a bentonite clay at ph 3.0 with 10% carbon added.

I have some of the Pure-flo Supreme 55 and Perfrom 6000 here that I’m testing out this week. I also have some Summit powdered carbon that I will try blending in to see what happens.

I know @Krative has mentioned that he uses the Supreme 55 with good results. Has anyone used the Perform series before?

I also noticed this interesting quote from Shadownaught in the beginning of the main CRC thread:

@Shadownaught

When I first began researching bleaching clays Pure Flow Performance 6000 was the first clay I tried. After trying other manufacturers we found out that Pure Flo wasnt the direction we wanted to go in. Performance 6000 was their best clay and only ‘performed’ about even with our current T5 product, except it was more expensive. T5 is our clay with the lowest activation level, the higher grades are not available through Pure Flo, I know because I tried to get them to make a product like our T41 to no avail.
