A "thank you " to those who replied to my paper kiln enquiry. I did the
workshop in a gale force wind so firing went faster than usual but got
interesting results by adding only copper sulfate and pickling salt to flax
straw combustable- mostly greens,ochres and a bit of purple-pink flashing.
What is the make up of Barnard Slip(also called Blackbird slip)? Someone
recently suggested that it is toxic-true?

Dear T. Howard,
I have worked with Barnard Clay to make a glaze by adding whiting in
increments of 10%, 15% and 20% and get a great black mat which does not run
with the 10%. Can't tell you about toxicity. I always used it on
sculptures. Two to three coats worked great brushed on. You can scratch
through it also for lines. Also used wax resist with good results.
