Cornish and British Minerals
I have been field collecting Cornish minerals for over forty years with several breaks while bringing up a growing family and starting my engineering business. It is not my aim to become a fully fledged mineral dealer as there are many other things in life to occupy my time as you will see on this site.
I have been lucky enough to acquire several very old collections over the years, some of the specimens from which are of no interest to me but are never the less of very high quality, some dating back to the 19th century.
Minerals Also Purchased.
The time has now come for me to specialise in one area of my mineral collecting hobby with the focus on minerals from the Mid Cornwall and I will always purchase good quality specimens from this area especially those from the clay country.

Super Iron Out / Iron Out. Now back in stock . Limited supply.
I am always asked what I use for cleaning iron stains from minerals and the safe answer is Iron Out or what used to be called Super Iron Out.
The fomula is identical and just an advertising decision by the manufacturers.
Unfortunately due to the huge increases in courier and customs prices I have had to increase my price so this may be the last batch that I import.
I can supply the 28oz bottles in the UK for £28.00 including free delivery.
I use a weak solution 1 table spoon to 1 litre of water and buffer with sodium bicarbonate to bring the ph to about 7.
As always test on a waste piece first.
