First glaze-fire kiln opening

Feb 28, 2006 5 Replies

Words cannot describe the incredible rush I got when I opened the kiln after the first glaze test firing of my pottery experience!



Thanks to the good advice I got from this NG, I felt almost competent going in. Also, again from someone's comment here, I discovered "Mastering Cone 6 Glazes," got a copy and used it as my basis for setting up glaze mixing (I never wanted to only use commercial glazes for some reason).



My wife and I made the trip to the ceramics supplier, got stuff, stuff and more stuff then mixed some tesat batches.



I honestly expected everything to come out black or muddy brown, all the tiles melted and the whole glob fused to the kiln shelf. Surprisingly, it was totally opposite. The glazes were beautiful (Waxwing Brown, Waterfall Brown, Bright Sky Blue, Variegated Blue, Gloss Base Glaze 1 and even an experiment I came up with.) Nothing was stuck down. Nothing melted. The only "near runs" were where I double-coated a glaze and got the total thickness too great.



The only problem I saw was some slight pinholing in the blues. All of them showed it, and none of the browns or the clear base glaze did. I soaked for



15 minutes at peak temperature. Maybe it should have been 30?

Anyway, now I'm *really* into it! Thanks again for the good advice.

Its important to soak the bisque too, then hopefully all the gases have been released and do not have to go through the glaze. Sounds like you had great success and more fun. Welcome to the incurable world of pottery. :o) A

More 'power' to you Fred, I like Annemarie's advice on soaking the bisque, something I hadn't given enough thought to; it's great that after fiffteen years of working with ceramics, people on this NG still have much to teach me!

Thanks to both of you. I didn't soak the bisque before, but I'll start doing it now. Fred

How long do you soak the bisque? At which temp?

Isn't it GRAND?!

I have had trouble with what I call little popped bubbles. There are two sollutions to this - as proved by my dealer, who just refired my pieces 20 degrees hotter, and by my teacher (who usually fires my stuff) by soaking 20 minutes longer. Both sollutions solved the problem.

Have fun!
