Antique Mineral Testing Kit – “Superior Blowpipe Set – With Extra Apparatus” by J.T. Letcher of Cornwall. Circa 1880-90. Retailers label overlaid, without loss of information – Tasmania: Hobart Walch & Sons; Launceston Walch Bros & Birchill.

Exceptional Museum quality example rarely found with so many remaining pieces. The only similar example we can find in this condition is displayed online at the virtual museum of the history of mineralogy referencing a “Private Collection”.

These field kits were used in Australia by explorers and geologists. They include apparatus and chemicals for grinding the sample, heating it and observing the colours in the flame to identify the constituent minerals. It has been used, which is great, but not effecting the quality of the contents.

Designed and manufactured by J.T. Letcher of Truro Cornwall and awarded the Society of Arts Silver Medal and the Colonel Croll Prize in International Competition in 1878. Each set guaranteed to equal that deposited at the Society’s House.

The use of the blowpipe was invented in Sweden in the 1700’s and further refined there at the Freiberg Mining Academy in the mid 19th C. This design by J.T. Letcher with its comprehensive accoutrements became the standard in the later Victorian period.

Original brass riveted mahogany box with escutcheon to lid. Contains a specially designed lift out tray with multiple compartments and layers containing tools, the blowpipe, a small anvil, rock hammer, spirit lamp and grease lamp, Numerous chemical reagents including the original “gold bead” in its tube. There is a agate pestle and mortar as well as a tiny crucible that we know was made by Royal Worcester.

The containers are made of box wood with names to top and with a lovely patina. Reagent bottles, miniature test tubes with labels, test tube holder and much more. Original platinum forceps.

The test papers box contains litmus, turmeric and brazil wood papers; along with Platinum wire and foil, tin foil and the tiny remnant of some magnesium. The minute bone spatula is still there … we could go on

The original under-label inside the lid describes the original contents and bar scissors we are struggling to see anything missing

The box still has it’s lock but the key is long gone. It has a worked patina and is still robust.

Something special in the mineral field. The Superior Set by the top maker of the day; along with respected Hobart retailer Walch label – try to find another one and then one like this!

Amethyst – Wave Hill Station – Northern Territory

A nice example with good crystal definition. Deep but smoky purple, clear at the root, Some hematite inclusions along one edge.

Amethyt is a quartz group mineral with trapezohedral crystals [six sides prism ending in a six sided pyramid].

The Greeks thought that it could counter intoxication and therefore carved drinking vessels from it – they really did have style. The not getting drunk idea is the Greek translation …

Whilst silicon dioxide is the foundation, iron creates the purple hue, other metals make subtle changes.

Wave Hill Station is a bit of a trek.

Weight 250 gm 9.0 cm by 8.0 cm x 5.0 cm matrix.

Wave Hill Amethyst could keep you sober …

Chrysocolla [Green Botryoidal Form] – Burra Burra Mine

A nice bright lump of the green chrysocolla from the historic Burra Burra Mine in South Australia. Distinctive botryoidal form.

Chrysocolla a hydrous copper phyllosilicate mineral of still debated structure.

The name ancient Greek and first recorded used by Voyager hero Theophrastus.

Chrysocolla can arise in a more blue form – we quite like the even underlying green tone of this sample.

It is of secondary origin and forms in the oxidation zones of copper ore bodies.

Weight 340 gm 9.0 cm by 8.0 cm x 7.0 cm matrix.

Stilbite – Western India – ex Werner Hoch Collection

A sizeable and attractive lump of stilbite from Vaijapur, Aurangabad District, Maharashtra, India.

We are told from whence it came that it was originally part of the Verner Hoch collection, the main part of which is now in the Natural History Museum, Vienna.

Stilbite [after Greek – stilbein “to shine”] is a tectosilicate part of the zeolite group of minerals. Formed often in a basaltic volcanic environment.

This example is characteristic of it’s found location [it takes various forms in different parts of the World – Iceland, Scotland etc]. Here we have a peach/ pink hue and a translucent characteristic. The large form is often described as a “bow tie” and you can see why. This is a particularly good example with larger forms sitting on a bed of crystals on the host structure.

13cm by 8cm by 6cm weighing 330gm.

Super example of Stilbite with dominant bow-tie structure – nice hue

Kalgoorlie Golden Mile – Western Australia – Original Magic Lantern Slide – Newton & Co – c1910

Very good condition magic lantern slide from Newton & Co Fleet described in cursive writing.

We date the slide to around 1910. New & Co were at 43 Museum Street London. They were the world’s longest established suppliers of scientific instruments being formed by Sir Isaac Newton’s cousin J. Newton in 1704. At the time of this slide the proprietors were still from the Newton family. The British Museum have Newton & Co out of business at Museum Street in 1913, but other references have it continuing

A really broad view which magnifies to present incredible detail. Standard British size in fine condition. We believe this slide and image is pretty rare.

Kalgoorlie was discovered by Paddy Hannan and Tom Flanagan in 1893. There horse had thrown a shoe and when they stopped to sort it out they noticed gold …. Well … on the ground everywhere. Hannan staked a claim and the rush was on. By 1896 the rail had arrived and the area had taken over from Coolgardie as the primary WA goldfield.

As an aside the Newton & Co address is as you might suspect in sight of the British Museum in London and also opposite The Plough … a favourite Voyager pub.

The Gladstone Colony [An Unwritten Chapter of Australian History] – J F Hogan – First Edition 1898

Published in London by T. Fisher Unwin 1898. Octavo, 279 pages. Original plum coloured with gilt lettering to front and spine and top edge gilt. A very good copy. From the library of writer historian Harold L Sheard with his distinctive bookplate at front.

Much about the goings on associated with the establishment of Gladstone.

Where we find it interesting is in July 1858 when gold is discovered on the Fitzroy River and then at Calliope. Mayhem ensues as it usually did and within a short time over 400 men were working diggings and making better than a good living – one man 100 Pounds worth in a fortnight 16,000 Pounds in today’s money. Inevitably followed soon after by a chapter titles “a host of disappointed diggers”!

The book on the establishment of Gladstone – and the gold rush.
