Crystalline glazes?

Hi again guys :-)

Just in case anyone is wondering, I managed to punch a hole in my biiig bowl as I was turning it (actually while I was testing to see if the bottom was getting thin!). Dropped the big bowl for now (into my recycle bucket) and have managed to finish a shallow bowl with a "half little bowl" inside that is for tea candles - you put holes in the big "dish", so the light from the candle makes patterns on the wall. Now all I have to do is transport it safely to the kiln! HELP! Hehe!

Anyway - back on topic. One of my fellow students is a chemistry-something-or-other and understands this glaze stuff something mean! She has lately been fascinated by the crystalline glazes, and I can see why, after having viewed a few pictures.

I was wondering if any of you do crystaline glazes or have links to good information, recipes or pictures about the technique. My friend is French, but reads both English and Greek, if you have links in any of those languages - or if you would like to share your information on here, we would both really appreciate it. She doesn't "do" newsgroups, so I thought I would ask for her.

Thanks for all input!

Do a Google search for Fara Shimbo. She is really a guru on crystalline glazes, and as I recall there is quite a bit of info on her Website.

Thanks Bob! I got 402 hits and have forwarded your tip to my friend. But of the 402, I am not quite sure which is her own website - it didn't top the list.

Anyway - I am sure my friend will probably have a look at all 402 hits anyway! ;-)

Thanks again

Marianne

A couple of years ago ceramic monthly had a very good article about crystaline glazes at cone 6. I think you can order back copies on the net. Might be worth a try. A

I was sorry to hear about your hole through your bowl experience. If you care for the future - if it is a piece you really want to save next time, there are many ways to recover a piece this has happened to. We have successfully put a 'Band-Aid's on bisque pieces that have gaps to cover. Glaze as you normally would then take a flattened piece of clay that you place over the hole or gap to cover generously (enough to still overlap edges of gap with shrinkage of the green clay considered but it should be 'thin' enough that it is not 'a thumb in the eye' - subtle) and put glaze on top of the bandaide. You can make the bandaide a decorative shape (star, shell, bird, flower) and it adds to the piece. This works for cone 6 firings where the glaze fits both the greenware and bisque ware. You can also on the greenware add a clay 'Band-Aid's. Take a flattened circle piece of clay and add over the 'hole' after having scored the edges of both pieces where they overlap and having added slip for glue. Wrap this nicely so that the moisture equalizes on both pieces (you can use a rib to smooth things to your liking). Once you are throwing more than you know what to do with you probably won't want to make this effort but when you are first starting out and each piece represents a large investment for you this is a relatively easy, fast and inexpensive investment of time and effort and can actually give you a 'learning' experience in decorating. Sorry to hear about the bowl.

Hi Dkat :-)

I have gotten to the stage now, where I just let it stand to dry thoroughly, then dump it in the recycle bin. I couldn't do that to start with - but now that I know I can make a new piece without spending hours centering, it is not so heartbreaking.

Actually, I spent hours making perforated plates to hang on the wall this week, but the perforated sides of the plates (just 2) dried too quickly and they cracked too much, so they are now also in the recycle bin. I consider my recycle bins proof of learning. No matter if a piece goes in there, I have practiced and learned something in the making anyway.

I have a new big bowl in the kiln now, so looking forward to glazing it :-)

Thanks for the sympathy, though - and the tips. If it were a huge piece, I might do something like that. But best of all is to be more careful when turning :-D
