I cooked on high and it went through all the stages within maybe 5 minutes of blending. The volcano stage was sudden and voluminous, unable to prevent it from overflowing a little. The gasoline stage followed very soon after the volcano. It got very stiff and difficult to mix. It already looked like a paste and was getting incredibly stiff, but all the recipes say to cook it for 3-5 hours so I assumed it was still lye heavy and needed to cook. I got stiffer and harder to mix (as expected form vids). I kept cutting it and spreading it as best as I could but it was so hard, just like HP bar soap, so I added some water (didn't measure) to combat evaporation. It helped a little to expose all surface to heat source to ensure thorough cook. I did this for about 30-40 minutes, only about an hour total cooking time. It surprisingly passed the clarity test, tested with phenophaline which was positive bright pink, but then passed the zap test. I zap tested several areas of the paste and it cleared. I was really surprised it was done so quickly. After measuring, I noticed that the recipe's "total batch weight" of 953g was more than the actual total batch weight of 879g, even after adding the water. (not much paste was left in the pot, maybe a 3-4 grams at most) dilute 1:1 or stronger. forms very thin watery LS. I diluted using IrishLass's mason jar method. I used 3 24oz jars and did 1:1 dilution in one, and the other 2 jars made a slightly stronger LS of 1 : 0.85 of paste:water. That means for the 1:1 dilution one, 16.6g of the LS has 8.3g of paste. For the stronger ones, 15.3g of LS has 8.3g of paste. For use in washing machine, DeeAnna says to sue 15 grams of her detergent per load, which is 1:1 ration of shredded 100% CO CP laundry soap and sodium carbonate (washing soda). Therefore 7.5g CP soap per load. Assuming her CP soap recipe used the usual 2:1 oil to water ratios, 7.5g of CP soap would be equal to 9 grams of paste if my total paste weight was 953g. But my actual total batch paste weight was 879g, so I need 8.3g paste per load. DeeAnna says to use 15 grams of her laundry mix (1:1 soap to soda) plus 15g of soda for her HE washer. But for a top loader like mine, using about 150L of hard water, it was suggested to double to soda to 30g. I will also make sodium carbonate (washing soda) from sodium bicarbonate (baking soda) by cooking it in a pan for an 1-2 hours in the oven at 350 until weight is 2/3 of original weight. 2(NaHCO3) -> Na2CO3 + CO2 + H2O Therefore, for 1 load in my 150L washing machine with hard water, I need 15.3g of stronger LS (or 16.6g of 1:1) and 30g of sodium carbonate.
