I was getting ready to reorder some Dowflake for my "improved to part recipe" and came accross some threads that said the 2007 batch of Dowflake contains some ingredients (borate?) that is not considered safe.
What is currently a safe choice for the calcium part and where is a good place to get it?
Thanks guys,
Greg
