Hi, and thanks for the compliments. I also have to admit I'm also staggered by the response, and also the length of this thread... will it ever end???
But there is no way I could have got so far in such a short time without the help of those contributors who have found new patterns, made suggestions, named the flamin' floral patterns for me and provided such wonderful photos — to be honest it's really the GMB's web pages, not mine! :oops:
To all these people, a sincere and heartfelt THANK YOU!You are right about the packaging: it has been covered within the site and there are three patterns that should help identify ages. I think this is in date order:
1. Diamond shaped (to 1971?)
2. Star shapes (possibly before the Diamond shape?)
3. Cross-line grid pattern (the last box style?)
But there might be earlier box styles yet to be found. The number written on the back (100) probably indicates the shape code. According to my documentation, this should be a 10" plate with plain rim? Once I have all these numbers I will compile [yet another] cross-reference.
However, your Daisy & Clematis pattern dishes are of particular interest because of the labels, which dates it exactly the same as my original guess. Daisy was introduced in 1970 or later and that's the end-date I'd given this particular label.
The Clematis pattern reveals the same 'Diamond' box style was still being used at 1971 or later, but the new logo on the label is pretty solid evidence of when this style of label was first used and when the old 'script' logo was finally dropped (now being used again by Chance Ltd).
It is therefore reasonable to assume the changes to the logo came about in 1970 when Pilkington assumed full control over Chance (previously they had a major shareholding).
The last item is referred to as 'Teardrop' – a new naming convention at this stage might lead to confusion!

This shape was first used no later than the mid-1960s (Swirl used this and the design was ended around this time) but I don't have a firm date. We have yet to determine the pattern name, but use Max's original 'Trippy Flower' name...
Thanks for sharing these finds: most illuminating.
