Judy,
I have a few of the Duncan crystal glazes that I got in a batch of stuff I
bought from another potter who was moving. They weren't something that I
would have purchased on my own so I've really experimented with them.
Although the ones I have say to fire them to ^06 I've fired them to ^6 and
yes you do get totally different results on most. However, I've found them
not to work very well on vertical surfaces. Best on horizontal.
Some totally change color at higher temp, some just almost disappear. They
become very very runny at higher temp.

Hi Judy;
Yes, I used to use those many years ago. They were lovely. No special
firing schedule needed at all. As a matter of fact, back in those days of
my low-firing glazes, I used to fire my kiln very fast and everything always
turned out. I would do a glaze firing in about 5 hours! After applying the
glaze, you can dig in and pick out some of the bigger crystals and stick
them here and there on the pot to get effects the way you want.
I have no idea what these used to make those crystal chunks. When I began
firing at cone 6 I was very disappointed to find those glazes were not
available at that temperature. However, re-reading your message you say
they can be fired at cone 5-6? I didn't know that. I wonder if they are
made differently now.

Hi Judy;
Further to my previous message about the Duncan crystal glazes. I took a
look at their web site to refresh my memory about these glazes. They DO
have lead in them, so be warned about that. And I don't think they fire
higher than cone 06.

Yes, years ago we fired Ducan crystal glazes on slipware several times.
Fired To 06. I don't remember the instructions saying they could be fired
to 5-6, but if that's what it says then it must be ok. I do remember that
the label said to keep the majority of the crystals high on the ware, and
this is good advice since the glass crystals flowing is what gives the
interesting effects. Either way I advise plenty of wash on shelves. good
luck and have fun!
