How can you inheal the dust when you submerge whatever in a
bowl of water ???
Better safe than sorry. Just remember, anything from the sea, you
die. Ground up shells contain poisonous hazardous substances like
arsenic. Do what you want, but I’m wearing a respirator that protects
against dust and mist. You should also wear long-sleeves as these
substances can be absorbed through your skin. I have heard this from
just about every rock person out at Quartzsite, especially recently.
I know a guy that ruined his lungs by working with abalone without a
respirator. Another friend of mine has no feelings in her feet because
she didn’t wear a mask when working with malachite & lapis 20 yrs ago
(her doctor said she had the symptoms of being gassed). You wear a
respirator when working with stones because you are breathing sharp
microscopic pieces of rocks that puncture your lungs, even if the dust
from the stones itself may not be poisonous. Go to www.
lapidarydigest.com and look it up.
I do all my work outside and I wouldn’t even consider not wearing a
respirator, even on a windy day. I don’t care if I’m the only person
in the world who wears a respsirator, I’m still gonna wear it. I also
wear a lawn and leaf bag with a hole cut out for my head and arms that
I can throw away before I go inside the house so I don’t contaminate
my home, and then I take a shower as an added precaution afterward.
People who polish abalone all day long also say to wear long sleeves
to protect against skin absorption.
I’m not telling you what to do, I’m just telling you what I do!
