Sorry, by "bad soap" I mean "excessive lye". pH testing can be used instead of zap testing to test for excessive lye.
Nope, and this seems to be the hub of the back and forth. pH testing will not, cannot, tell you anything about exactly what is IN that soap. This is not an opinion. It is an objective fact, that can be tested out in a laboratory. And there isn't a reliable, easy, inexpensive test OTHER than the zap test that will reliably determine the presence of excess lye. This is, again, not an opinion. It is objective fact. There are ways to determine the presence of excess lye, yes. They are not available to the average home soapmaker. The zap test is. This is why people get so ardent about promoting it. If you come up with some other way that is reliable, easy, and cheap, we WILL be interested in it. pH strips are not that answer.
