Thread: The evidence

A bloke I worked with uses his artist wife's chrome green oil paint as a polishing compound for his plane & chisel blades.

That's just daft! The artist's oil colour is just that – it wouldn't contain any abrasive medium.

......why not?
is it not a remote possibility it could be both a really nice colour and an abrasive?
Ever wonder how these things came to be known and used?

I have used a process to texture silver and gold by painting the back surface with yellow ochre, then heating the front until that surface bubbles.

yellow ochre + heat = Ferric oxide (red)
(known also by those good folk in the north of Aust. from 60,000+ years ago)...
Ochre - Wikipedia, the free encyclopedia

now...
Yellow ochre + linseed oil + some dryer or wax or other stuff = yellow oil paint

BTW Ferric oxide is jeweller's rouge....the red stuff I use daily for polishing gold and silver.
The only difference is the carrying medium.

Don't you use a whole range of these oxides for colouring reproduction / restoration of furniture....I've watched Rob Brown work his magic with them?

Peter

Maybe slightly off topic, but did you ever manage to replace the filter? i need to replace the clapped out on in my Aldi Vac.

Dunno. It seems that some chrome green paints contain a mixture of yellow & blue iron oxides, others contain chromium oxide.

Acshully, they probably do! Unless its soluable dye it will be some sort of ceramic stain which is oxides cooked a bit with fluxes and other things to make them inert. So kinda artificial oxides. Purists prolly still use the actual oxides.

I suppose it is possible, though the grade of pigments used in artists' oils is much finer than those generally used by restorers. Some colours of 'restorers' grade' pigments are coarse to the point of being semi-translucent when mixed with carriers or binders.

Texture aside, there are a number of artists' colours that retain their original names, but contain none of the original ingredients. Most of the lead and other metallic colours don't actually contain lead or metallic ingredients any more due to their toxicity.

I use a number of pigments including red lead which are illegal in paint products now and unfortunately, their modern synthetic counterparts don't have remotely the same properties. However, I can (with some difficulty) obtain the old 'pigments' via other sources.

To be honest, AlexS' work mate could easily have obtained the same honing advantage using just linseed oil without any green colourant present if he poured some onto an MDF strop. Oiled brown paper was a popular stropping medium in the past.

At any rate, the dog is home in one piece (well, minus his nads actually) and was given a clean bill of health.

The Ryobi filter from Bunnings is a direct replacement and a much better item to boot. They also sell a good pre-filter.

That's cos paper has Kaolin in it! And why your mum tells you off for using her good dress making scissors to cut paper!

WW, I suspect that chrome falls into the classification of banned chemicals, and that most chrome green paints now contain a mix of blue & yellow iron oxides.
Personally, I just use a leather strop with a bit of Scheppac polishing paste & oil.

Now that makes sense! Thanks for that little nugget.

Some glossy and quality paper and card is indeed finished with minerals such as kaolin, but the majority isn't. Cutting paper will not dull well maintained scissors.

Some craft workers even recommend cutting fine abrasive paper ocassionally in order to sharpen their scissors!

just noticed this reply. Dunnow which planet I've been on lately, but thanks for the info

The CrOx bar prob had mostly a fat carrier so was attractive to a treadmill-exploited pup desperate for calories.

Let's hope Hugh Wirth doesn't read this forum.
