Hi Mathew,yes I know about linseed and drier additives from previous experience of having made traditional oil scumble mixtures for faux graining and marbling. In my previous posts I thought I had made myself more clear I didn't necessarily believe olive oil was the answer to cold blacking compound I need for the mill gears. That is why I originally thought of waxes and latterly Danish oil. John's compound has worked real good on the stove and I will use it more in the future for that purpose.....OZ. Thanks for your contribution it's all really useful to the thinking it out process |

Is that why it's so hot today! :coffee: I assure you it wasn't lit for a moment longer than needed,the back door and windows were all open and I retired to yard with a cup of tea. On a side note, as I have been gradually improving my house insulation levels over time and fitting replacement low emissivity glazing it shows as lower temp setting on the wood burner being required and quite a lot less fuel throughput...even when it is freezing cold outside. By the time I get the underfloor space insulated I'd guess it will be really economical to keep the place warm........OZ Dave [/quote] |

I'd go with Danish oil but EXTREME CARE with the rags you apply it with. As you no doubt know it can self ignite in rags as they dry and mixing graphite with it might accelerate this. For ease have you considered a quick blow over with acrylic matt black lacquer first to give effectively a back ground black then applyyour Danish mix over the top? Danish on metal works ( you should see my lathe bed sometimes) as a rust stopper. :med: |

Eureka! Found an ancient tin of Danish oil this morning (and a bottle of quick drying linseed oil) Some old graphite electrodes were powdered up nice and fine and a paste mixture created by the addition of the Danish oil. For test the mix was applied to some old iron castings kicking around the shop,dried and rag burnished and bingo I have exactly the result I'm looking for. howsitwork,I fancy that the addition of the graphite powder is indeed accelerating the drying time for the oil. The rags etc.were all escorted of the premises soon after the job was done......OZ. |

A little update to the experiment: So I thought why not give the Danish oil mixture a try on a hot surface like my wood stove. If it goes wrong I can always scutch it off with coarse wire wool and a wire brush. ...No such worries,I did the whole stove with the Danish oil and graphite paste let it dry,fired her up and raised the temp slowly to very high and let it cool. A quick burnish with an old shoe polishing brush and a soft cotton rag and all is black and lustrous. Ran the stove for a few hours since and all is well. So it seems fair to say that and the the olive oil mix are both winners.....Doubleboost,double bonus...so to speak....OZ. |
