Hi Christine,
The vast majority of published glazes are not evaluated for durability or
food safety. This does not mean that some of them will be suitable but
rather - most of the glazes we see are used because someone likes the look
of them and they fit the particular clay they are using.
The sad part is that those publishing glazes simply do not attempt to
evaluate them and/or label them with appropriate information.
Because most potters are so desperate for usable glazes and are so lacking
in formulating skills - they simply take whatever is offered.
The net result is an abundance of poorly constructed glazes which give no
end of trouble and make it difficult to produce good functional ware. You
would think that it is hard enough to make a living at making pots without
having to work with inferior glazes and clays.
I think I can fix your spitting glaze - if you would like to send me the
recipe I will try - RR
