Oh my, that was a typo. Yes of course I will be firing to Cone 5 this time, not Cone 05. I’m new to ceramics but not daft or dumb. I am willing to risk firing them all at once because firing one tiny thing in a big kiln has more downside to me that just going for it.

Well nothing blew up. Everything is intact. Obviously the clear glaze is more translucent rather than glossy because the kiln did not get hot enough. So my question is whether I should add a new coat of clear glaze or whether I should just fire to cone 05.

OK, I will cross my fingers and be very careful.

I had already set the kiln running the Cone 05 program yesterday afternoon. I will open the kiln this evening and see what I have. I have reglazed and refired pieces that did not work out before. It’s a risk, but it’s the only option I have at this point - add more clear glaze and fire to cone 5. Thank you for you advice because I will now be more careful to check what cone to fire all the products I put in the kiln.

It’s Georgie’s PG630 Zinc Free Clear Gloss Glaze that fires to cone 6

Amaco Velvet underglaze says fire to cone 04-05. So I I think should be ok. I’m so new to all of this and there is so much to learn technically. There is no detail work on any of the pieces. They are all just one or two colors. So there is no risk of the clear glaze smudging anything. I wiped the bottom edges so hopefully nothing will stick to the kiln shelf. I did add only clear glaze to the interior of each piece, so hopefully that does not cause the clay to expand or crack. We will see…

So don’t bisque fire since I have already glazed with an underglaze and clear glaze?

I created some small ornaments with Amaco terracotta clay no. 77 which has firing temp range of cone 05-5. Recommended temperature is cone 5. I let the pieces dry for a week and have just added a couple layers of underglaze and a layer of clear glaze. I would normally fire my Skutt kiln on an auto program of cone 05 medium speed with no ramp/hold time. But I have never made my ornaments with terracotta and am uncertain about firing. Will all be OK at cone 05?

Thanks for the advice and warning. I think removing the glaze from the bottom rim is my best option.

I am making stands out of high temp wire so they hang above the shelf. I hope this works.

I have made a bunch of conical tree ornaments, I bisque fired them and glazed them today. I would like to glaze the interior of the cone as well as the bottom rim. But that leaves no place for it to sit on a kiln shelf. What is the solution?
