Well lime is slightly soluble in water. Meaning If you used too much lime chances are a lot of your yield is lime.
Try melting a little bit of your product on some aluminum foil.if a large portion of it remains unburned, or doesn't melt chances are what you have is a lot of lime. Although this is not a definitive test, this could be a good starting point.
It's been fun. Thanks for all the wisdom.
