A great knapping stone for both beginners and advanced
knappers, heat treated Novaculite is famous for its predictable flaking and easy
workability. Our current stock is mostly porcelain white to off white with the
occasional band of translucent quartz, grey or pink; some spalls may be the
fully translucent variety.
stone is mined and heated in-house to control quality and consistency from out
of the quarry to your doorstep. Hundreds of tons of overburden and
weathered 'rotten' novaculite must be removed before we see the first spall of
nice clean stone. We only use digital temperature controlled kilns to
ensure that the stone is heated properly to the optimal temperature for the
right amount of time.
We strive to provide the cleanest, blemish free knapping
material within our means. On some spalls however, blemishes do get past us
because not all defects are evident at first or even second inspection. In
efforts to avoid defects as much as possible, we perform a few thinning blows to
ensure that you do not pay for large amounts of waste, over thick spalls, or
fragile/thin sizes that will shatter with the first strike.
Large knapping material requires large billets. Attempting
to knap large stone with too small of a billet will damage the billet and not
produce sizable thinning flakes early on in the process as needed. If you are
graduating to this size material from one of our kits, we recommend adding a
large copper percussion billet to your order. If you are unsure about what you
need, please visit our Flintknapping Buyer's
Guide, or feel free to contact us and we will
be glad to help.
Information on Novaculite
Novaculite is a form of chert found in the Ouachita Mountains of Arkansas and
Oklahoma and in the Marathon Uplift of Texas. Novaculite is considered to be
highly siliceous sediments and may be a product of the low-grade metamorphism of
chert beds. The strata were deposited in the Devonian Period and subjected to
uplift and folding during the Ouachita orogeny of the Pennsylvanian/Permian
Periods. Novaculite is very resistant to erosion and the layers of novaculite
stand out as ridges in the Ouachita Mountains.
Novaculite is a form of microcrystalline or cryptocrystalline quartz. The color
varies from white to grey-black and the specific gravity shows an increase from
2.2 to 2.5. The very hard dense rock is commonly used as a whetstone. It has
been mined since prehistoric times both as material for use as arrow and spear
points and as sharpening stones. Moreover, the upper strata of Arkansas
Novaculite, known as tripoli, has found a niche within the coatings, adhesives,
sealants and elastomer industry as a performance additive or filler. Tripoli is
mined in the Hot Springs area of Arkansas.
word novaculite is derived from the Latin word novacula, for razor
