Hello Ahmad, I'll try answering your questions on fast-firing bodies and
glazes.
Monoporosa/Monocottura; I think may be synonymous and refer to ware that is
once-fired (no bisque) to maturity - in the floor tile industry we use the
term Monocottura.
A fast-fire glaze for this product is formulated using frits and basic raw
materials such as, feldspar, kaolin, ball clay, calcium carbonate, silica,
zinc oxide; with great attention being paid to particle size of the milled
glaze.
These products are fired in about forty-five minutes in roller-hearth kilns.
As to the 'Protective Glaze'; this might refer to a 'cover-coat' glaze,
usually clear, used to protect screen or otherwise printed surfaces from
excessive wear.
Sorry, I'm not at liberty to post specific formulae on this list.
Is your friend starting a production facility, and where are you? I may be
able to give you some contact numbers/addresses, depending upon your location.
Cheers,
Alex

Dear friend,
For a friend who is investing on clay products, I need the
following information pertaining to "fast firing glaze" and
"protective glaze."
The following items are of most importance:
- raw materials (percentage of each constituent if possible)
- grain size
- suitable biscuits
- firing conditions
- any other important information that may be needed.
These information would be used in actual workshops.
Thanks for your consideration.
Yours sincerely,
Ahmad Mokhtarifard
