CS>storage question

[Teresa Jessee]

I am new to silver making.  I bought a machine from Utopia.  The lady there 
told me I could store my silver in a plastic bottle.  But I have read here that 
it needs to be stored in glass.  Would it be OK to store in plastic just long 
enough to collect a half gallon to use to soak my horse's feet?  Should I throw 
away the half gallon I have stored in plastic for the last month?
TIA,
Teresa
