I was going through a mound of orchid emails today and although this
is two weeks late I just had to post a response…
Brian you’re absolutely right you should not put it down the drain,
but I am appalled you would say the best thing to do is to pour it
into the ground! You should never pour chemicals, especially acid
into the ground!
Ferric Chloride should always be stored in acid safe pyrex or the
containers that premixed ferric chloride come in. Sodium
bicarbonate(1/4 cup baking soda nad h2o) can be used to fully
neutralize metal, etching pans, etc. When I etch I always dispose of
all materials used during etching, such as tape, paper towels, etc. in
ziploc bags labeled with contents. As far as the ethcing solution…
most premixed ferric chloride solutions can be used again and again,
assuming there aren’t contaminated at all. When the time comes to
rid, you should contact your local waste facilities, there have the
resources to dispose of it along with other waste materials properly
instead of into the ground!!!
It is possible to use hazardous chemicals in a safe way to make art
jewelry, and it is sooo important to respect the environment when
doing so.
