I did think of this but decided that the guillotine crush marks would be a pain to remove, thank you for your suggestion though.

Have you thought about using PMC? If you had some square cutters you'd get them done in no time.
That is exactly what I thought of Carole when I read this question this morning and said nothing because I thought it might work out expensive, though it would surely give the opportunity to have varying thicknesses easily and that little something extra one gets from the slightly organic nature of the PMC.
.... and you could use one of those plastic chip cutters you use in the kitchen to cut multiple squares at the same time.

Reason: an extra thought
Another good idea though to make a few hundred would I think work out very expensive for what they are, I need around 40 for a necklace and 24 for a bracelet. They would then be 999 silver which would not tarnish and the organic handmade look does appeal to me, may try that, gram for gram the casting route seems the best option but thanks Carolallen and Kwant, always good to hear your ideas.

I cannot let this subject rest without another suggestion. It just grieves me that you are proposing to pay out good money for something you could well do yourself, or get into using overpriced clay. You will find that clay brings with it its own problems.
Rectangular wire can be bought in various useful sizes and could be quickly cut to equal lengths, to make squares, on the chenier cutter mentioned above. If you have a rolling mill you can first roll this down further as required. If not, you would get a better return investing in a mill than paying others for services or using clay.
By the way, fine silver does not get fire stain, because that is copper oxide, but it tarnishes like Billio, because that is caused by the formation of silver sulphide. To prevent your stock from tarnishing keep it in a closed box, or polythene bag with an anti-tarnish tab. Regards, Dennis.

Many thanks Dennis, I had discounted the 'over-priced silver clay' I already knew that it did not tarnish because of the absence of copper but I didn't know of the formation of silver sulphide, I have noticed that it does go brown though and that explains it, thanks. I have a Durston Mill and will certainly investigate the square stock idea.

Buying 8mm or 6mm strips in varied thickness's from Cooksons is what I do at the moment and at around 70-90p per gram (dependent on choice and quantity) it isn't too bad but as I said labour intensive. The casting route is probably a good one because the basic metal price is cheaper 60p/g (ish) I would incur casting costs and the unit price would then probably be about the same, the finishing time though would be less and as long as the original masters were of a suitable standard it might work.
I will have another look at the square stock and maybe have a go, the 6mm square would be less of an outlay to try so I will give it a go. Not sure who can supply 6mm and 8mm stock but I will have a look, many thanks Dennis for taking the time to think.
