WHERE INFORMATION AND PROSPECTORS UNITE  
 
 

Vreeland Spectroscope

 

Normally prospectors are totally reliant upon laboratory analysis to determine what a rock contains.

Obviously, the more a prospector knows the better and is less reliant upon others. However, because no one knows everything and the Earth is full of surprises it behooves a prospector to be as equipped with as many tools of the trade as possible.

Today, gizmos with flashing lights, dozens of levers/knobs and impressive gauges connected with bewildering battery of wires to high tech computer software that makes strange noises is the trend. Although these modern widgets are exciting, one must keep in mind that all instruments have pluses and minuses. Therefore, because of the old cliché – garbage in garbage out – I am skeptical of instruments utilizing computer software that only PhD’s can comprehend.

In the quest of identifying unknowns I believe that the below instrument cannot be beat for its mechanical simplicity and cost effective semi-qualitative/quantitative analysis. Although it was late in the game before I was fortunate enough to get my hands on this wonderful tool, it was nevertheless better late than never. Not only have I been able to make discoveries, reduce my dependence upon labs, but also be able to verify my wet & dry assays.

As a result of being blessed with this tool and in the interest of saving the prospector a ton of money and irretrievable quantities of time I wholeheartedly advise those who seek minerals to purchase a magnificent Vreeland spectroscope as soon as possible.


Learning how to use this instrument is quick and easy.
Plug it in to any 110V wall socket. There are two buttons regulating high/low burn temperature. One knob adjusts electrodes and one knob raises and lowers the sample into the arc of electrodes. Two knobs adjust the films to distinguish the elements and a moveable up-down lens to view the generated visible light spectrum associated with the film.

The Vreeland equipped with a Cannon 12mp digital camera to record either single images or video clips of the generated spectrum lines as the mineral sample is melted and/or volatilized. With the camera I have what I consider to be a decent spectrograph and the saved images allow me to review the results.
