SP "not food safe" disclaimer

So looking on Sp website for some annealing temps and saw the "... Not food safe, may contain lead and other chemicals." They have this disclaimer on the bottom of all their pages in a sort of general way but then it is also on their color page , bolder, which makes sense there, but does this mean no drinking glasses or bowls are to be made from their clear batch? I find it vague and confusing. Any thoughts, anybody?

SP contains no lead at all. It is certainly food safe but the stance from the container industry dictate that there be no lead within 1/4 inch of the lip on drinking vessels. That would include any decoration on the surface and would include any color on the cup from rod, inside or outside. There's nothing to fear from the clear and you aren't navigating legal issues.

Usually, that means "not safe for long term food storage" because of Leeching of bad stuff over time, ok for intermittent use. They did the same to the potter's glazes years ago. You can still drink from lead crystal stemware.

correct, but you can't use lead crystal decanters.

a little clarification

Pete, so when you said no color on inside or outside within 1/4" from lip/rim does that mean color that has been encased also? Does trimming through a color that is encased now expose it partially or does it get sealed from the action of trimming?

thanks
fredi

I don't know. Tom Littleton had the gory details on the subject a number of years back. Perhaps it's in the archives. I recall it being more about surface decorations on the lip exterior.
