I guess he did eat that stick of honing compound...

[Waldo]

Mustn't have been very nutritious :no:.

No, but I bet his innards are well polished.

[Ozkaban]

You'll be right, WW. It will probably still work just the same :o

You're right! It still works a treat!

Excellent! Another stool WIP thread:)

WW,
I KNOW you have to keep the tripoli polishing compound away from the dog...it is a bar of animal fat (of some sort) with the grit in it.

That green stuff is chrome oxide, and I believe it isn't good for you at all if you ingest it.
Don't know if the same applies to animals...??

He doesn't appear any the worse and has eaten two full meals since he had the opportunity to eat the compound yesterday afternoon. He's also eaten two interlocking foam floor mats, an Aldi vacuum cleaner filter, a barbeque cover and a Mallard drake without any obvious ill effects.


He's off to the vet's in the morning to be tutored, so I'll make sure he gets a full check-up then.

He's obviously trying to build something in there. Watch he doesn't poop a shiny glider and escape.

tea lady,
the "green rouge bars" were being used at least in the 1930's, they are called that , and "green oxide bars" in a book I have. The thirteenth edition of a book on polishing and electro plating. ( Canning, originally published in 1889.)
Chromium oxide is a grayish / green powder, it is sometimes used for gem polishing, but is usually used for polishing hard steels and chrome plating.
For me it is the polish for platinum and hard (nickle alloyed) white gold. It has been used as a polish for platinum since it's use in jewellery became popular in the late 1800s and early 1900s when platinum replaced silver as the premium setting material for diamonds and other gemstones. Platinum has many wonderful properties, one is that, although it is relatively soft, it has a very high resistance to abrasion. So it resits polish...hence the use of the chromium oxide polish. (also it doesn't wear away easily like white or yellow gold claws on top of a diamond)
It has a major drawback in it's use as a jewellery polishing agent in that it contaminates / consumes the chemicals used in the refining process used to recover gold & platinum. So my metal refiner hates it...and charges extra :~....but it seems the grease base used for these bars (animal fats used so it melts at a specific temperature to allow the cutting agents to be released) ..... is very tasty.:U
Jewellers with a dog or a cat in the workshop for company know this stuff has to be kept in a draw or a cupboard.:U

(always have a giggle behind the hand when the VEGAN types who won't wear leather, but will wear jewellery, use eating utensils, sit on, and wear products made of steel and plenty of other things, that have been polished with compounds mixed in animal fats...if only they knew)

I use it as a pottery glaze colouring. :shrug: Its usually a darker green. Actually I don't use it very much. Cos it s ay dark green. ::rolleyes: Have used it in chrome tin pink glazes too. That was fun. And even MORE deadly. :doh:

Yes, one of them. He's the one I use for ageing mirror plates.

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.

[lightwood]

WW
......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 (http://en.wikipedia.org/wiki/Ochre)

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 (http://www.robertbrown.com.au/) 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. :2tsup:

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

[tea lady]

That's just daft! The artist's oil colour is just that – it wouldn't contain any abrasive medium.Acshully, they probably do! :shrug: 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.

[Woodwould]

WW
......why not?

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! :cool: And why your mum tells you off for using her good dress making scissors to cut paper! :rolleyes:

[AlexS]

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. :)

[Woodwould]

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!

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