He also apparently invented this, which is unrelated, but a very nice implementation of an idea I've seen before from one of the major toilet fill valve manufacturers, that a person on a well system had installed on their toilets. His implementation of a flexible wire arm with a paddle to enable a cycle on the fill valve when you press the flush lever, looks more reliable and easier to set up than the one they used. Especially good to have if you are on a spring or well system of limited production capacity or with not a huge tank, where losing all your water could be a big problem, costly to replace or, even a disaster, if you are very remote... But then you probably have an outhouse instead of a toilet. Still won't protect you from a failure of the valve it's self to an open condition, or a leak in the supply hose outside the tank, but will eliminate water lost to incorrect or changing fill height that occurs with some valves, and cycling of the valve when there is a slow leak past the flapper valve at the bottom, or worse, the chain is left too long and periodically causes the flapper to never close at the end of the fill cycle. youtu.be/nXV2GnWrnn4 |

Karl...
Could boric acid be used in any acid activation process (not meaning zeolite necessarily)
Does acid activation work at all with zeolite or is that just good for clays?

Hope the videos get everyone thinking and sharing ideas, as I lay out my intended variations on and optimizations of this basic idea...
I'm pretty sure if I put his heat collection coil into insulated mass bell, it would be a steam, rather than a hot water generator.

Boric acid is a very weak acid with rather low solublity. It is mainly used as a PH buffer. Acid activation works especially well for layered minerals like clays and minerals with high alkali content, especially potassium. Zeolites are not layered nor do they have high alkali contents. |

Thank you Karl... I think I might have asked you this in a more general way, previously, but I want to ask specifically regarding my use of bentonite.
Could it be beneficial to exfoliate part of my bentonite into a second binder with some form of acid before adding that to then alkaline based zeolite binder, then aggregate water, then "aggregate portion of the bentonite? Or will the unreacted lye and acid in the two binders somehow destroy the mix or the polymerization process?
Or might it improve my "too much lye" indication from the excessive bubbling of the surface of my previous bentonite free samples, and minor bubbling of my bentonite one?
If it could work, I am assuming this would apply to other clays as well?

Yes, it could be beneficial but may depend of the kind of bentonite.
Sodium bentonite has the highest water demand.
Calcium bentonite is often be converted to sodium bentonite,
but this converted sodium bentonite has not exactly the same properties as natural sodium bentonite.
Traces of remaining calcium may cause bubbles with acids.
Just test it.

Ok... Thank you! And would these bubbles be obvious at an acid initiated geopolymer formulation (or stronger)acid concentration and relatively absent with natural sodium bentonite?

As I could only get the converted kind I do not know about the other from personal experience.

... provide a single example, of multiple ways to benefit from these home built, high efficiency combustion systems. MagRocket or Rocket-Mag ... +extras. F Styles build a brilliant one a year ago but there was a falling-out on this forum. His thread is still up on Permies. |

This is being sold as kitty litter, and I can't see them wanting to invest chemical or other energy into conversion, unless there is some benefit in that application. This is what the bag says about it.  |

The temperature here had raised by about 15°C and thus my cellar became warm enough to test the Sweet PDZ sent by coastalrocketeer . He only sent me the finer particles without granules, thus I could not test how well the granules can be dissolved. Hot tap water here has about 60 ° C. Sweet PDZ and NaOH were mixed in dry state in a 3/1 ratio and then several small amounts of hot water were added while stirring. The Sweet PDZ dissolved quite well. The brownish Sweet PDZ does not swell as much as the greenish zeolite I get here. Very likely this is due to differenses in electrical surface charge caused by slightly different chemical composition and has no significant meaning. I have mixed some cheap white casting clay with 20% of the Sweet PDZ binder, 5% cement and 1% rock wool. The casting clay is a ready mix of white clay with about 20% alumina content and feldspar. Pottery suppliers in the USA do not seem to offer something like that. I will report the outcome later. At about 12°C it has started to harden and gained some strength just 90 minutes later. That is pretty good so far. |

Yes, what I sent is sold as "powder" though I have found occasional "granules" in the 3-10mm range and a good portion of it seems to be in the 0.1 to 0.5mm range... Which I would still call "granules"
The one vendor near me only carries the powder version.
3 to 1 is a higher lye content than I have tried, i believe.

In the 60g sweet PDZ for the binder
I have found only one larger piece of about 10mm,
which was a powder clump easily squeezable with a spoon.
By stirring a bit in the rest I could nod find another clump.
Maybe the powder got wet in the silo.
There are no zeolite rock granules.
This powder may allow a 4/1 ratio with a lower lye content.

The Sweet PDZ powder is fine enough to be used with KOH.
All pieces larger than about 0.2mm which I found are powder clumps.
The clumps could be sieved out and powderized with a blender.
Even though the airborne particles were removed the Sweet PDZ powder is quite usable.
A bit more heat may be helpful to compensate for the missing airborne particles.
