From the Chemicals Cupboard
This time the cupboard yields a new price list. As you will no doubt have guessed, some
have gone up...... but there are falls too, mainly as the result of buying larger
quantities and having a better idea of the actual carriage costs. This does mean that if
demand falls (or my arithmetic is wrong) they will have to go back up again - so keep up
the weighing and mixing. Several items have been added to the list, in response to
requests from members and also the result of new formulæ. (Ammonium bromide for
Lawrence's latest E6 for example, and ammonium thiocyanate for anyone wanting to try out
silver mirror prints).
I have changed the name used for the calcium complexing agents to the shorter and
simpler "Anti-Calcium..." It's also a lot simpler than the proper chemical names or
other trade names.
