I use slightly more than 2 1/4 cups per gallon but I bake it at 450 degree for 1 1/2 hr and I heat it with a heater.

And what does baking it for longer and at a higher temperature do?

It drives off more CO2 to give you more Na2CO3 (sodium carbonate) from baking soda (NaHCO3 which is sodium bicarbonate)
2 NaHCO3 + heat ---> Na2CO3 +H2O+CO2
Sodium carbonate dissolves easier than sodium bicarbonate and that's why recipe#1 can be more concentrated. Baking it longer with higher temp will convert more baking soda to sodium carbonate. Make sense?

I always make 5 gallon at a time. And I just add the baking soda all at once straight from the oven. A power head mixes it up with a heater in the bucket. In a couple hours, they all dissolve. BTW, I use 2 large boxes of arm and hammer which is 1.8kg each to make 5 gallon, so it is 2 3/4 cups per gallon instead of 2 1/4.

Oh, one more thing, you have to spread the powder over a large baking tray to get more surface exposed to the heat.

ok chris the batch i made just fully dissolved in the bucket.. what i did was placed the baking soda on a baking sheet let it do its thing in the oven at 400 degrees for 1 hour and 1/2.. i also stirred the baking soda on the tray about 45 min. into the baking...
I had the rodi water already heated up to 90 degrees from a heater... i took a cup at a time and sprinkled it in and kept stirring while sprinkling it in.. also had a small powerhead moving the water... had the bucket 3/4 full after adding all the baking soda, I topped off with the 1/4 of water I had taken out of the bucket and its all good.... nuthing left over and water is clear...
