[UPDATE: I have to point out that all the low temp "cerro--" alloys have lead and cadmium, and are toxic. You need to use proper ventilation, and keep it away from food preparation areas.

The objects you make *won't* be suitable for food preparation or food containers or utensils of any kind, and probably not for kids' toys either. FWIW, I've seen several gunsmithing how-to videos that don't mention toxicity of the Cerro-lines at all, and they aren't using ventilators either, but they should. For all
