(g) The spongy lead may be bulged, or the positives may be buckled.
Positives do not swell or bulge as they discharge, but shed the active material.
This occurs in the negatives also, though not to such an extent as in the positives.
If the positives are buckled, the negatives will be also, but not to the extent that the positives are.
In the case of the positives, there is no remedy, and the plates should be discarded.
Positives which are rotted and disintegrated are, of course, hopeless, and must be junked.
The positives are 1/4 inch thick, and the negatives 3/16 inch.
If you intend to use some of the positives, they should now be washed.
Positives which are only slightly warped or buckled may be used again.
I have used nothing else for positives on glass since I discovered the preparation.
