In Topic: Metal, Clay And Kiln

12 October 2014 - 01:10 PM

Yep! It was a thread I started lol. I was using key shavings in clear glaze. I got deep greens at ^06 where the shavings were densely populated. At ^6 I got white, light green, and a lot of blue variegation. I did a simple test at ^06 once and incorporated it in clay and slip but no melting action happened. I never did that test for ^6. J baymore and others noted that the key composition is not primarily copper, nickle, or steel but can actually have a high amount of lead. You can also get further evidence on that because there is a lot of warnings out there to not let you infants suck on you keys as toys.

 

So really it depends on what you fire and make. If you never do functional ware then have it! The lead vapors "infect" you kiln and will hang around. So if you only have one kiln and do/plan to do functional ware for food uses then I would opt out of such an experiment. You might risk contaminating you kill with lead and then in turn your wares.

Yeah I dont know if it undergoes any process before its crushed into different mesh sizes. Ill probably do a test bar on my next firing which is a bit further down the road. The only ventilation my kiln has is the peep holes. Its an old knob operated paragon. Ive never attempted to fire with the lid cracked. There is a metal hinge that will prop the lid about an inch but Ive only utilized it during lower temps to dry pieces.

Silk screen slip the logo onto the clay. Should be thin enough not to disrupt the dough shrinkage.

Jim Gottuso does this to his stuff using lacquer. Although the artist in question maintains some very clean lines.


In Topic: Water In A Studio Without Plumbing: Ideas Needed

30 May 2014 - 12:19 PM

I dont use this for my studio but because we run off a well I havent been wanting to take hundreds of gallons of water for my aquaponics. So Ive used 55 gallon drums as rain barrels which you can find for very cheap and add a bulk head fitting on the bottom. Recently, I took an extra cut IBC tote and placed it near a gutter. The gutter catches an 8 by 8 area worth of tin roof and during the last storm I got 150 gallons worth of water. Totes can be found as cheap as 50 bucks in most areas. You could very easily set one up in an area that is advantageous and have a lot of water at your disposal after a rain. I hooked up a hose so I utilize the gravity and pressure but Harbor Freight sells good water (fountain) pumps at very good prices. Pretty sure a small one inside the bottom of a tote with the outlet directed horizontally to where you need it, through a bulk head fitting that is, and have it linked to a lightswitch as your on/off could work well. Pumps are rated for the GPH and Head lift. Im sure pushing horizonally will give a little bit better performance than pushing out and up the tank then down again.
