Bruce - I have been making CDS with Charlotte's recipe since she first posted it here - a couple of months now.
I have had zero issues or concerns with pressure build-up. My only problem using canning jars has been corrosion of the ring lid. I have since bought a liter glass jar with a glass lid and a rubber ring for the seal which is closed with a wire snap tensioner. We are doing 20 drops NaClO2 28% with 100 drops 10% CA. I have measured the 100 drops CA into a measure and now just fill the measure and drop it into the shot glass.
We then place the sealed jar into a plastic basin and flood the jar with hot water up to the seal level. This then takes 3-4 hours and the shot glass is clear. Removing the CDS to a glass bottle (500ml) we add another 500ml of clear spring water and refrigerate. This gives my wife and I two doses each over two days. Leaving it int he fridge for a week leaves is in the same condition as when made.
I have since changed my shot glass for a tiny liqueur glass with a stem and foot which "stands" in the reaction jar and is more stable. The neck cross section area is 1/4 of the shot glass and this results in a slower off-gas for some reason, and I now have to re-heat the jar twice over 8 hours to get a full reaction.
Overall we love this method as since starting taking CDS - no more funny guts or diarrhea at all.
I also made a small ebook which I attach here on the system we use with the original canning jar as most folks we supply have them. Also have had nil negative feedback from any of these people.
My only current concern is the rubber seal on my "sweetie jar" seems to be cracking and will eventually fail due to the corrosivenes of the ClO2. So I will stock up on spare seals, but have averted this degradation with using cling film in the lid seal between the rubber seal and the neck of the jar with good results.
