I would like to know why the people on this list feel the need to add H2O2 to EIS ??? If you make the EIS correctly then the addition of H2O2 creats as T.E. that should not be there !!! Switch to assymetrical electrodes as two othe people on this list have, and you like their product. When I made their systems I asked them to not reveal it as i am not in the business of making EIS systems. When my booklet comes out in a couple of weeks it will detail the process, and why one should do somethings. Diagrams, data plots, T.E.M.s the whole nine yards, even and invitro comparison with the best. "Ole Bob"

In other words, did one batch cure longer than the other before you added the H2O2? Someone has indicated that the reaction of the CS to H2O2 is different depending on how fresh the CS is or how long the CS has cured. On the new brew, perhaps try taking smaller batch quantities and adding H202 to these smaller quantities at different times relative to when the CS was made. EG, using the same brew: Batch 1 has H2O2 added immediately after it has been made. Batch 2 has H2O2 added 3 hours after it has been made. Batch 3 has H2O2 added 6 hours after it has been made. Batch 4 has H2O2 added 9 hours after it has been made. Batch 4 has H2O2 added 12 hours after it has been made. Batch 5 has H2O2 added 24 hours after it has been made. and so on...
