Couple of notes on the glaze medium:
-- Used in THIN layers, it dries nice & flat.
-- It takes MUCH longer to dry than ordinary thinned or un-thinned acrylics and even longer to actually "cure" (set)
-- If you go too heavy, the glaze will take on a gloss
So: go easy ... allow ample drying/curing time (I'll usually allow overnight) ... and resist the urge to mess with it before set.
If you screw up, go too heavy & get a bit of gloss (which I still do occasionally) ... let it fully set, then a couple light coats of Tamiya TS-80 Clear Flat spray will kill the gloss. (And, in general the TS-80 beats the crap out of Testor's dullcoat ... but that might just be my very biased opinion!)
Cheers,
Dallas

Urine has been a traditional non-ferrous metal patina for centuries.  |

Horse pee will blacken oak shavings , something to do with the ammonia in the pee . Though I suspect you will have to have some pretty potent pee to blacken aluminium .
Do you want me to send you a pint or two of horse pee to have a bit of an experiment ? ! ? Or is your own toxic enough ?

A video clinic on this process would be most welcome Nick, especially the part where you convince the horse to pee into a cup.... Paul |

You know, this just proves that there are too many people in this world with video cameras and too much free time on their hands... Paul |

White Oak + Ammonia = Fumed Oak. Think about the Stickley furniture from the late nineteenth century. In the woodworking industry, the effect is done by placing the completed piece of furniture in an airtight box and exposing it to ammonia fumes for up to 24 hours. At the end, when the piece comes out of the box, it is a greyish colour. Rubbing a coat of wood finishing oil on the piece brings out the rich almost black colour associated with Stickley. Fuming cherry will make pale pink new cherry timbers look as they have over ten years of patina on them over night.
I once fumed an entire room of white oak bookcases and paneling because after the client saw the finished room. he wanted it a bit darker. We placed trays of blueprint developing grade ammonia in the room and checked it every other hour until the desired colour was reached. Since there was a lacquer finish on all of the wood the change took several days. BTW, don't try it at home, because that much ammonia in a closed space can KILL.
