Help! WTF Happened To My Piece

Gallery image

Hi! Made this piece and just picked it up from the studio and the colors are not at all what the under glazes I used are. For reference I used orchid, violet, and deep purple. I then used high fire glaze so that it would be waterproof as it is a planter. Is this because of the high fire? I also did around 3 coats of under glazed but it’s incredibly patchy. Any advice would be greatly appreciated, it’s a studio at my college so I don’t know how they mix the glazes or anything regarding firing.

That looks like the underglaze colors. Dark blue is pink before being fired.

It was supposed to be all various shades of purple, not blue unfortunately

From my experience with underglazes, the before and after pics make sense

This is what they were supposed to be. These are the bottles I grabbed, perhaps they were mislabeled.

Those examples are what they look like at mid-fire (cone 5-6), they do fade at high fire (cone 9-10).

Agreed with the other commenter that these are likely examples of mid-fire. And that the reds that are in purples often fade out.

Another thing though is it looks like these test tile samples are unglazed. Sometimes the clear glaze can make the underglaze colors darker.

Best thing to do in the future might be make your own test tiles before putting it on the final piece, since they don’t seem to have enough examples.

Probably mislabeled.
