Aged Lime Putty
Natural Pigments Aged Lime Putty is of the
highest purity for intonaco and other plaster
coats. This lime putty comes from our own lime
pit, aged at least two years and has been
extensively tested for use in fresco. With lime
of this purity it is possible to create brilliant
fresco painting that will have excellent
permanence. Also, can be used for a variety of
plaster finishes, such as marmorino, Venetian
stucco, scraffito and scagliola. Slaking
quicklime for a long period of time enhances the
workability and body of lime used in construction
and restoration applications.

Slaked Lime (Calcium Hydroxide)
Perfect medium to make lime putty, milk paint,
limed resin Calcium hydroxide, traditionally
called slaked lime, hydrated lime or pickling
lime, is a soft white powder and obtained when
calcium oxide (called lime or quicklime) is mixed
or "slaked" with water. The name of the natural
mineral is portlandite. A suspension of fine
calcium hydroxide particles in water is called
milk of lime. The solution is called lime water
and is a medium strength base that reacts
violently with acids and attacks many metals in
presence of water. It turns milky if carbon
dioxide is passed through the solution, due to
precipitation of calcium carbonate.

Pumice
This grade of white pumice is used to polish
surfaces on wood, and added to chalk and gesso
grounds to give it tooth. Our pumice is a
near-white, milled volcanic glass that has many
uses in fine arts. Add pumice to paint to make it
appear mat when dried, to add texture and to
increase body without tinting the color. Pumice
can also be added to grounds to give it "tooth"
and as an abrasive to smooth and polish
substrates and grounds. This grade of white
pumice is used to polish surfaces such as wood,
and added to chalk and gesso grounds to give it
tooth. This grade of pumice is white so it will
not discolor grounds.

Perlite
Perlite is a amorphous volcanic glass that is
processed so that it is greatly expanded and
white. It can be used in painting grounds and to
increase the bulk and give texture to paint. Our
perlite comes from the Nu-Alexite and Socorro
perlite deposits located in New Mexico, U.S. The
ore is formed by magmatic processes, usually in
"domes," that over geologic time periods entrap
water into the matrix. The mechanism through
which this occurs is not completely understood,
however, it is this entrapped water which gives
perlite ore it's unique ability to expand.

Pozzolana
Pozzolana is ground vocanic ash composed of
siliceous and aluminous material from Pozzuoli,
Italy. Use in fresco painting to make hydraulic
plaster for stronger walls. Pozzolana, also
known as pozzolanic ash (pulvis puteolanus in
Latin), is a siliceous or siliceous and aluminous
material which reacts with calcium hydroxide in
the presence of water at room temperature (cf.
pozzolanic reaction). In this reaction insoluble
calcium silicate hydrate and calcium aluminate
hydrate compounds are formed possessing
cementitious properties.
