the "sled" honestly looks totally different between the 2 . the newer one is very much darker, which makes me wonder, does it make a difference when firing over texture? will it turn more brownish? more darker blue? the glare in the video is really bad ....
If they were the same you wouldn’t be able to see the line. Also people are seeing a huge difference in their work so this is why they are doing the videos about these. We are ALL seeing a big difference.
How would you suggest glazing the inside of a flower vase like you have. Can you just add a little water to the glaze and pour it into the vase and then dump out the excess?
I'd like to make a suggestion...if you watch this video with the sound off, it will become apparent how much you are moving and flipping your test tiles around such that the viewers have a tough time seeing the differences in the glaze. Please keep the tile STILL or use a stand. You are moving too much! Also, the lighting needs to be adjusted so that there isn't a glare on the tiles. If you want a great video production, think about presentation as well as information you are conveying.
We changed from using a buff clay to a white clay. It's been over 12 eyas since we started making the color label tiles, and at the time we started they were all buff. We have switched to white stoneware for newer glazes since that's what we're using for layering and ads. ~Cara
No I’m not seeing beige it’s a much darker blue than the top colour. I don’t see any brown even holding it sideways as you did you can see it is two different colours
Yes, absolutely, it does. Any semi translucent colors will deepen over Obsidian, not just Blue Rutile. Try a layer of Seaweed, for example. Over black it turns a pretty blue.
I'm afraid it looks more different in the video than it does in person. I was concerned about drift in PC-20 Blue Rutile before doing the sled test, because 3 coats of PC-20 older than 3 years compared to a batch from this year was very different. The sled test reassured me that the bigger difference was that the glaze is going on thinner, not that the color is dramatically different. After this test, however, the Lab agreed to increase the viscosity of PC-20 so new batches are coming out more blue with fewer coats (because coats are going on thicker). PC-20 is a glaze that has experienced more drift than most of our glazes (due to mined resource changes), but with good application it still develops the floating blue. I'll see about photographing the sled test is good lighting to show the similarities. ~Cara
The sled test does look a lot darker with the newer glaze with the lighting here.
The sled test tile shows two different colours. The bottom colour is much darker as I view it?
The newer version of the glaze is MUCH darker than the older version of the glaze. And the flat glazed dish doesn't look at all like Blue Rutile.
Love the information. But I wish they had a better quality camera. It's always grainy, difficult to really see the colors.
To me the colours look quite different too, one blue (newer glaze) is much deeper than the other.

Thank you Cara.
I actually like the darker blue!
Did you ever show the vase you’re working on, once fired?
The two blue shades on the one large tile,, the SLED,, look like 2 different shades of blue,, the one almost looks teal.

Yes, exactly. ~Cara

What was the purple colour glaze you showed us? Is that the colour of the new blue rutile in the jar?
Yes, that's the newest batch of Blue Rutile. ~Cara
Why on earth would the label tiles not be all the same clay? This is beyond frustrating.

I would also like to ask why, when you are glazing a piece you apply two coats at a time and let it dry? You’re actually putting on 6 coats??
I apply glaze to the entire form, smoothing it out, and then let it dry. That is one coat. ~Cara
No I’m not seeing beige it’s a much darker blue than the top colour. I don’t see any brown even holding it sideways as you did you can see it is two different colours
Will one coat of obsidian underneath make it more intense blue?
Yes, absolutely, it does. Any semi translucent colors will deepen over Obsidian, not just Blue Rutile. Try a layer of Seaweed, for example. Over black it turns a pretty blue.
The “sled” clearly looks like a different glaze, and that star dish looks nothing like the older Blue Rutile. Why not just be honest with us?
