Knowing now that a hydrometer reading is relative rather than absolute, and
with the advise of the other clayart members who shared info on hydrometer
usage, I would get one immediately if I knew how to measure the specific
gravity of a super-refined terra sigillata such as you make. Would you
consider sharing your secrets for obtaining a "high-luster" , "one-coat",
"single polishing" terra sigillata? Your recipe? Information on adding the
colorants you use? Also, when you recommend the sig to be applied: i.e.
leatherhard, dry greenware, bisque, etc? Which cone do you fire to? Do you
apply to a low-fire clay body or high fire?
Thanks!
