I have released a hard shelled stone from the Liver Flushing protocol. Others have released hard stones as well. The article indicates that the soap stones are formed by mixture with calcium, primarily through ingestion of milk fats or cheese. Beside the fact that we are all doing a solid 24 hour fasting period during the protocol, I do not have milk fat or cheese as a component of my normal diet. I am vegan. I have also gone into this protocol with a preceding day of juice fasting, hence no kind fat exposure. People have gone into this protocol after extended fasts (such as the Master Cleanse), with no fat, particularly milkfat exposure. They have produced stones. It is possible that some of these blobs are soap stones, but I do not believe the evidence indicates that for all of them.
Thank you for your interesting contribution to the discussion.
