I failed to mention that the composition of the pugged B-mix is different
from the slip version of B-mix. My pugged B-mix came in 50 lb boxes with
two 25 lb bagged blocks each, while the slip was a powder that came in 50
lb bags. I added the water and sodium silicate myself. Got the slip
viscosity down really tight and specific gravity down really tight and that
is really important with slip casting. All the handles for my mugs were
molded and poured solid, This allowed me to make any shape I wanted then
attach it to the mug. and I could repeat the design exactly. While so many
are enamored of the potters wheel, slip casting offers whole new vistas
into clay work.
