I have just received an email telling me that the European Chemicals Agency intends to put lead in all its uses on a strictly controlled authorisation protocol, preventing its use without a special permit. This is of particular concern to conservators and manufacturers of leaded glass, but would also prevent the setting of ironwork in masonry. Lead on roofs of course would be banned entirely. Even museums would not be allowed to conserve leaden artefacts without a permit. Although the UK is no longer in the EU, it is entirely possible that laws will passed that follow the ban.
