Any update on this? We want a genuine Cooltone developer!

And while on the subject - I have about a half bottle of warmtone that seems to have gone bad. The bottle is heavy and almost certainly airtight (seems to store well before the foil is removed) but once the foil is removed it is not. You can (with a really good grip) squeeze most of the air out of the bottle but it will inflate again in short order. The next Ilford liquid developer I buy will be immediately decanted into other bottles, but it shouldn't be too much to ask to package it in a bottle with a lid that will seal air tight.

But mainly we want our Cooltone.
