William -
I have found that any very soft cloth works well - old cloth diapers,
flannel, or tee shirt material - but BE SURE to remove any seams, pockets,
buttons, etc. Use only the part of the cloth which has no seams.

I have started using terra sig as a burnishing slip - it gives a better
burnish than any other slip I have used. After burnishing with a polished
stone, I finish burnishing with the tip of my finger, and I can get a satin
gloss almost as shiny as glass.

One of these days I'm gonna get me a website and show ya!

I use very fine sable watercolor brushes when I apply terra sig. Brush holds
lots of liquid, brush hairs never fall out, and you rarely see brush

Dip or pour. or use better brushes.

And something about observation, my new batch of white sig covers in one
coat as opposed to 4 with previous batches. Same specific gravity, same
bisque temperature. Hmmmm. Ok, so now we only dip once. ;-)

Dear Luke Lamar,

You say <sig.>>

The last time I priced a good Sable for water colour painting I was =
quoted about Au$120.00 for a No 12. I this the sort you are talking =
about, Kolinsky Sable from W & N.

I got a nice Chinese Deer Hair a couple of weeks ago, a good fat body =
about one inch diameter and white hair about three inches long for =
Au$14.00. Nice tool.

Best regards,

There are so many good man-made brushes available now.
So why deplete the stock of wild animals still further?

It is by our sensible choice of materials that we can make a difference.
Even if it is only a small amount of hair from a hare.
