A glaze problem solved

I use 33% barium carbonate in my copper blue glaze. About a year ago I started getting some bubbleing where it got a little thick. Lots of seconds. I tried other bariums but they all seemed  grainy. Finally Sheffield pottery came up with a smooth precipitated barium. Problem solved.

This material is completely smooth and fine. Overlapping glaze is not rough any more.
