Tidying Up An Analoy 1401 Alloy Analyser
vtsteam:
Well clay definitely has silicon in it and often iron, too (particularly red clays) among other elements, and is a frequently used binder for lower quality "graphite" shapes. So though not a conclusion, is at least a possible explanation.
nrml:
Will it be possible to work out how much the iron and silicon increases and deduct it from the results or does this vary with the strength of the arc and from pencil lead to pencil lead?
awemawson:
Good questions NRML but I don't have the answers !
I have some 2B true 3.0 mm leads on order so they will at least fit the collet better but I expect they also will contribute elements to the analysis. As Steve says the clay binder is sure to have at least Silicon in it.
I'd hoped that if I could find pencil leads of the same hardness and blackness rating I'd be home and dry but thinking about it different manufacturers will achieve the same rating suitable for artistic use and indistinguishable BUT using differing constituent elements :bang:
Ideally I need to find somewhere / someone that can analyse / grade / identify what the proper electrodes are made of - I'm keeping the used ones on the off chance I find someone.

Analyse a piece with an original electrode then test the same piece with a new electrode. Look at the differences between the two analyses and then rewrite the firmware :lol:
