Easy Gesso
An easy way to make real gesso. This is not an
acrylic "gesso" mix. It's the real thing hide
glue and whiting (chalk). But we've made it real
easy Mix equal amounts of warm water and the
Easy Gesso powder, wait a few hours for it to gel
and then warm it until it is liquid enough to
apply with a brush. Can also be applied cold as a
soft gelatinous mass similar in consistency to
tofu. The difference between real gesso and
acrylic "gesso" or primers is silky soft surface
that is absorbent to water-based paints.

Rublev Fluid Medium
Rublev Fluid Medium is a multi-purpose, vinyl
acetate ethylene (VAE) polymer emulsion. Rublev
Fluid Medium dries to a clear, soft and flexible
film. Rublev Fluid Medium is ideal as a sealer
for protecting against Support Induced
Discoloration (SID), a condition resulting from
impurities that are drawn up through an unprimed
substrate as paint dries, discoloring the paint.
Rublev Fluid Medium is also useful for diluting
and extending colors, increasing flexibility and
film integrity, sizing for fabric, and sealing
wood. Rublev Fluid Medium will wet out solids,
including pigments, more readily than other
polymers and is useful for artists formulating
their own paints.

Tempera Ground
Rublev Colours Tempera Ground is formulated with
a polymer emulsion that contains high levels of
titanium dioxide, calcium carbonate and
wollastonite to produce an easily sanded surface.
The surface is very absorbent and specifically
formulated as a ground for tempera painting,
providing a surface ideally suited for egg,
casein and collagen paint.

Verona Red Marble Dust
Verona Red marble ground to medium coarse powder.
Use this marble dust to make grounds, for adding
textural and handling qualities to paints, and as
filler in lime plastic for the intonaco layer of
fresco. Imported from the world-class deposit in
Italy, it is ground to a granular particle size
of 0 to 0.07 mm to retain its crystalline
shape. Marble is calcite formed from limestone
with heat and pressure over years in the earth's
crust. The pressure causes the limestone to
change the particle structure, causing it to
recrystallize. Fossilized materials in the
limestone, along with its original carbonate
minerals, recrystallize to form large, coarse
grains of calcite.

Alabaster
Alabaster (also called satin spar) is a natural
crystalline mineral of hydrated calcium sulfate
mined near Volterra (between Florence and
Sienna), Italy. Softer than chalk (3 Mohs scale
of mineral hardness), its hardness of 1.5 to 2
makes a soft white gesso that is easier to polish
to a smooth finish for gilding bases and painting
grounds. Calcite or chalk, being a carbonate,
effervesces on exposure to acids, whereas gypsum
alabaster, when so treated, remains practically
unaffected.
