My ancient jasper looks black and has a few spots that the red/green coloration came through. I think I needed to apply it thicker. I am going to re fire it with another layer. :)

I just fired a half dozen pieces to ^6 using the PC20 as a base coat with Palladium, Chun Plum, and Vert Lustre as topcoats on different pieces of Soldate 60 clay. The colors were darker than in their ad, and I'm attributing that to the clay.  One thing I did find out was that you do not want to use the PC4 Palladium as a base coat. I put it under the PC20 Blue Rutile as an experiment on a mug. The colors blended but were kind of a muddy dark blue and the glaze ran to the point where I had 5 gross drips at the bottom of the mug. The interesting thing here was that the drips were all the silver color associated with the Palladium telling me that the Palladium as a base coat was NOT the way to go. The glazes held together well with the Blue Rutile as the base coat.

My next attempt using these colors for layering will be on B-mix clay, and I'll be thinning the top coats to see what happens.

Thank you for sharing this information! 

Looks like the colors are almost always darker than in the Amaco's ads. I do not think it is the clay, as I used these glazes with the different clays, and the result was still the same. I finally found the right thickness, but it took a while.

 

Thinning the top coat will only make it muddy darker. Keep trying different combinations. I started another thread where I suggested to share positive information about using the different commercial glazes, so maybe some day you could find a good info there. It's called "Commercial glazes: good experience."

Hi, I am having the same issue with ancient jasper.  I applied 2 coats without thinning and it was quit thick and pretty much got straight black.  So if I thin it out with (water?) and apply 4 coats in opposite directions this should solve the issue?

 

Here are two images of my sample:

Thanks in advace for your help!


Best Regards,

Ancient Jasper is a tough glaze to work with. If you want the advertised glaze, you REALLY have to go pretty thick. Like, 3-4 coats straight out of the jar without thinning. And even then, it's not as much "Jasper" as I'd like.

 

The best results I've gotten from it are layering. It really performs well over other glazes, specifically Amaco's Firebrick Red. That's the closest that I've gotten to the advertised test tile.

1-2 coats of ancient jasper

That ugly dark purple-brown in Image 02 is most common look Amaco Ancient Jasper has created at our studio.

 

 

Definitely applied too thin when it looks like that., (although I actually like the colour and make use of it at times with a thin application).

Thanks.  Do you use a slow-cooling program, or do you let the kiln temperature drop by itself after you reach cone 6?

 

 

When I started using PC glazes I had no choice but to just let the temperature drop, my newer kiln will allow me to do a slow cool down (and it does promote better iron reds) - but I haven't actually used Ancient Jasper for a while.

 

I'll find something to put it on for my next firing (they're fairly infrequent) and really slather it on, (with a catch plate).

 

I'm going to try your floating red too, got two or three new glazes to mix and test - when I can source a few more cheap containers. :)

Hi all! I just got a bunch of PC glazes in an effort to find a dramatic, reduction-looking red. I am trying to achieve the red advertised by layering Oil Spot over Blue Rutile. I *thought* I'd applied it pretty thick, but this is what I got:


Any ideas? Is it really possible to get that red?

I also like the effect I get using a turkey baster or similar syringe type thingy.  I syringe the glaze on.  It goes faster than a brush and goes on thick enough that I don't need to do it more than once.  I can also get a nice uneven application by overlapping the syringed layers somewhat.

I have started playing with some of the potters choice line and my all time favorite right now is PC-20 Blue Rutile. I like it alone but I also really like it with Firebrick Red. In the kiln right now is a bowl with blue rutile under Indigo Float, I'm anxious to see how it comes out. I raised it up but am still a bit concerned about runs I guess I'll see. I have another bowl glazed but not in the kiln since I ran out of room with indigo float over blue midnight, I'm anxious to get the next load fired so I can see how it looks as well.

I want to do some more experimenting but need to make some shallow drip pans before I'll feel comfortable going all out with the different glazes and layering.

I have had some luck with Palladium, though am struggling with pinholes in anything bigger than a pendant size. Doing some research it seems to be an issue it has with little loafers.

Want to get some more of the potters choice colors but need to sell some stuff before I can buy another sample pack.

Terry, will you post a few pictures, please?  Reading through this thread has me intrigued.  Best of luck with the firing!

Are any of you getting the silver from Palladium that the adds show?  I have tested it thick thin and very thick and still get black.  at ^6 with a slow cool.

Does anyone get "true" celadon from "True Celadon"  I get almost the same as a powder sold by my supplier as "Transparent Green".

 

I do, however, like Plum Chun, and Blue Rutile is not bad.

I have had very bad luck with potter's choice glazes. I agree they all turn out really dark and muddy looking. The only one I ever use is Palladium which i've had a lot of trouble keeping from running.

I've had lots of trouble with palladium. I apply 2-3 coats and fire it to ^6 with a 15 minute hold. It's usually that nice silver but is occasionally that ugly black. I have also found that it looks especially silvery under a clear glaze.

I found my trick to using ancient jasper. If I apply a thick layer of deep firebrick and then apply 2 thick coats of ancient jasper, I get a look more close to the advertised photo.  I also find it pretty with a few hints of saturation gold here and there ;).
