ABSTRACT
The topic of utilizing cassava and freshwater snail (Agurong)
as raw materials for producing colored chalk is an interesting
and innovative area of research. The study aims to develop an

Freshwater
snails
(Agurong)
are
abundant in the Philippines, mostly in rural areas. However,
almost all of the people discard the shells with no further
use, resulting in a great number of shell waste. This waste
can be repurposed as the main material of chalk, which is
calcium carbonate. As 98% of the composition of a freshwater
snail (Agurong) is calcium carbonate, it is a great substitute

INTRODUCTION
The “Jagora Asperata” is a species of freshwater snail
that is unique to the Philippines and can only be found there.
(Madhaystha, 2019) There is plenty of marine and freshwater
life that is important and valued by Filipino people. Out of
2,400 species, at least 65 species in the bodies of water have
solid
commercial
value.
While
Freshwater
Snails
(JagoraAsperata) and Asian Clams (Corbicula fluminea) are the
most abundant species present in the Philippine waters.These
species are abundant and well-known to spawn all year in the
country. It is considered a delicacy in many parts of the
region,
mainly
because
it
is
believed
to
have
nutritional
value and source of low-cost protein. Because of the high
demand for these shells, it has also been a great number of
shell waste. In general, when the flesh inside the shell is
removed the waste shell is discarded with no further use. But
the wasted shell still has a usage, wherein it is used in
making chalk and also helps lessen the waste shell that is
dumped anywhere by most people.
According to Hobart King(2005), chalk is a variety of
limestone composed mainly of calcium carbonate derived from
the shells of tiny marine animals known as foraminifera and
from the calcareous remains of marine

algae known as coccoliths. On the other hand, according to
bioone.org freshwater snails(Jagoraasperata) are composed of
95-99.9 % calcium carbonate by weight. The Freshwater snail,
also known as agurong in its native habitat, served as one of
the subjects of this research that is used in making chalk as
it has the main element needed in the production.
Chalk is used all around the world. The main function of
chalk is of course to write, mostly used by teachers and
students in school. The chalk made out of Freshwater snail is
safe because the concentration of the calcium carbonate is
less compared to commercial chalk that’s why the chance that
it
irritates
the
eyes,
skin,
respiratory
tract,
mucous
membrane, and digestive tract lessens. They are also a lot
cheaper than using whiteboard markers and whiteboards. Also, a
typical Filipino school setting uses the traditional way of
teaching which is using chalk and blackboard.
Cassava flour is made by grating and drying the fibrous
cassava root. It is a great substitute for wheat and other
flours, and is a versatile ingredient that can be used as a
thickener in a variety of food recipes and products. One of
the key properties of cassava flour is its ability to absorb
water and create a thick, creamy consistency, making it a
popular choice for thickening products. When using cassava
flour as a thickener, it is important to measure the flour

accurately, as too much or too little can affect the texture
and consistency of the final product. It is also important to
be aware of any allergies or sensitivities to cassava, as some

A. The Making of Cassava Flour
1. Peel the cassava and chop into small pieces to make it
easier to blend.
2. Put it in the blender and pour in a few cups of water.
Blend until the mixture is fine and uniform. Take the ground
cassava and wrap it in dry cloth. Press the cloth tightly to
fully flush out excess water.
3. Put the ground cassava out in the sun to dry.

B. The Making of Agurong Powder
1.Thoroughly clean the agurong shells inside and out, then
prepare the bamboo stems and put the cleaned shells
in it. Start a fire under the bamboo and let it stay for 10-20
minutes until the shells become fully white.
2.Once the shells turn white, put out the fire and let it cool
down before taking out the shells and wash the shells again to
clean out ash and dirt.
3. Crush the shells under mortar and pestle until it becomes a
fine texture.

C. The Making of the Chalk
1. Pour in 1 cup of cassava flour and 1/4 cup of agurong
powder in a bowl and add 1/2 cup of water and 3 drops of
liquid food color and mix until a uniform texture.
2. Put it in a small hollow bamboo and let it dry in the sun
for 5 days. After 5 days, split the bamboo in half and take
the chalk out.

not perform well after being soaked in water. The strokes were
not as visible as they were before, indicating a loss in
quality. On the other hand, the chalk made from agurong and
flour maintained its quality and was still visible and usable
after being soaked in water. In conclusion, the results of the

makes it a suitable alternative for use in environments where
exposure to moisture or water is likely. The test highlights
the potential benefits of exploring alternative materials for

improve the performance and durability of chalk.

RECOMMENDATIONS
The researchers recommended the following:
1. Future researchers could explore these factors and also
investigate the feasibility and scalability of using cassava
and
freshwater
snail
as
a
sustainable
alternative
to
traditional chalk materials. This could include assessing the
availability and cost of these materials, the potential for
local sourcing and production, and the social and economic
impacts on communities involved in the production process.
2. Improving the durability of the chalk made up of cassava and
figuring. Determining the optimal amount of calcium carbonate
that is needed in the production as a reinforcing material
will provide the desired improvement in the durability of the
chalk.
Enhancing
the
durability
can
ensure
that
it
can
withstand repeated use without breaking easily.
3. There were slightly flying-grained dusts of the produced
chalk. Future researchers can consider adding materials like a
small
amount
of
water-soluble
wax/paste
chalk to reduce or lessen the
to
the
mixture
of
amount of dust produced by
chalk. Reducing the amount of dust created when writing or
erasing on chalkboards, making a cleaner and more convenient
option for classrooms.
4. The coloring food used as a tool for the color of the chalk
leaves a stain on your fingers when used. Water-based paint is
a
good
solution
because
it
can
provide
vibrant
and
long-
lasting colors without leaving stains on your skin. It's also

easy to clean up with soap and water, making it a convenient
alternative to traditional chalk coloring methods.
5. The molds are the main component in making chalks. It is
available in plastic, rubber, and bamboo. In choosing a molder
you should consider if it is easy to break or the chalks' are
easy to be removed. To remove the chalk out from the molder
faster and easily, lubricants are used for preparing the mold.
A mixture of groundnut oil and kerosene is used for preventing

molds.
The

protect

surface from sticking the mixture to the mold and also helps
to remove the chalks easily.
