Jon,
I kinda thought it was something like that, I have studied Boolean logic and have used it extensively, in my work, but have no experience with what you call British logic, is there any relation--?
Sorrycantseeme,
These questions are answered in your study of safety.
My arms are all scratched up from logging in the woods, I would not want any toxic salts that I can avoid in those scratches if my arms were not all scratched up, I still do not wish to have toxic salts of metals or acids in my face on my hands, in my eyes, in my lungs, in my bloodstream, in my drinking water, in soil I grew food to eat from or that would leach into my well.
I would not worry you most likely not die tonight if you wiped the few drops off your arm, How much toxic metals salt or acid that get past the layer of your hide and into your bloodstream (well it may take time to tell).
I would worry more about understanding the dangers, understanding how to work safely protecting yourself from getting poisoned, your lungs full of liquids (from fumes) how these metals can enter your bloodstream, how the can dissolve in the rain and poison a whole town downriver making them sick, How it can penetrate the building or area you live in and slowly silently poison you...
I would not worry about dying tonight if you wiped your arm off, I would worry more about you harming yourself your family and others by not studying and leaning the dangers and how to take safety precautions and use safety gear, store the chemicals, mix chemicals and metals and not have some glassware blow up in your face, breathing toxic fumes, fill the walls of your work area or home with poisonous fumes or toxic metals.
There are many dangers involved and many things to study to learn to be able to work safely in a chemistry lab, and in a gold or silver refining lab.
we also have more specialty labs that may work with especially dangerous chemistry working with highly toxic metals we can include the platinum group here, radioactive metals, hard to control toxic gases, acids, caustic solutions, organic chemistry labs, medical and disease labs, it takes much more study and an understanding of the dangers as the dangers are higher, precautions and lab safety equipment...
Basically, before mixing metals and acids you need to study diligently, you can make something that explodes, blinds you, destroys your lungs, your liver and whatever other bloody organs you have in your gut, burn you, poison you, make your baby sick or worse...
What we do is dangerous in many aspects your only protection is to educate yourself.
You do not get gold from mixing acids and metals, you get gold from what you know from educating yourself.
You get hurt or harm others by being uneducated and unaware...
