Hi
I need web based sources of information about various commodities
which are available at least monthly, but ideally weekly. These will
be free sources and not paid for content.

If you can only find some of the sources, then post a clarification as
to which ones and I will consider agreeing to pay if there are no
other offers. Thanks in anticipation of your help.

The commodities are:

Gypsum crude ex-mine UK
Perlite Raw Graded Bulk
Perlite Aggregate ex-works UK
Perlite Filter delivered UK
Perlite Filter ex-Works USA
Caustic Soda fob European Union
Chlorine spot - UK
Ethanol spot synth200 - UK
Hydrochloric acid spot - UK
Hops dried Czech 
Glucose Corn Sy wet US
Acid Caseine (UK & US)
Caustic soda - Global pricing
