在Cuttlebone上 雕刻圖案, 是既便宜、簡單又具有特色的一種鑄模工具.
其紋理的表現是獨特的,這也是我喜愛它的原因.

烏賊骨
烏賊擁有一個內部結構稱 烏賊骨(cuttlebone),
由碳酸鈣組成具有多孔的及滲透性很強骨結構,
因此藉由它提供烏賊的浮力。浮力可隨意調控-
烏賊能決定下沉或上,就是根據調整氣體與液體進入氣孔的比率 。
各個種類有不同紋理,形狀、大小, 和樣式在"骨頭" 上。
傳統上Cuttlebones 被珠寶商和silversmiths 使用和鑄造成為鑄件。
比較普遍的,現今這種材料常拿來餵小鸚哥和其它寵物鳥作為補充鈣的來源。
cuttlebone 對烏賊來說, 是他們獨一無二的的特點,與其它烏賊親戚截然不同的。
Cuttlebone
Cuttlefish possess an internal structure called the cuttlebone,
which is composed of calcium carbonate and is porous,
to provide the cuttlefish with buoyancy.
Buoyancy can be regulated — the cuttlefish can even decide to sink —
by changing the gas-to-liquid ratio in the chambered cuttlebone.
Each species has a distinct shape, size, and pattern of ridges or texture on the "bone".
Cuttlebones are traditionally used by jewellers and silversmiths as moulds for casting small objects.
They are probably better known today as the tough material given to parakeets
and other cage birds as a source of dietary calcium. The cuttlebone is unique to cuttlefish,
one of the features contrasting them with their squid relatives.
因為cuttlebone 既便宜又易雕刻, 我一口氣刻了三個圖案, 做了三樣作品.
之前上銀飾課學過, 灌鑄的是銀,
這次我們用pewter (錫與鉛、黃銅等的合金)金屬來灌鑄.
Pewter 比銀的熔點低很多, 所以這個模並沒有被燒焦,幸運的話還可以再灌一次金屬.
等金屬冷卻就可以把灌鑄口多餘的部位切掉,
就是一件墬子成品了.

墬子上頭的灌注口鎔渣需要被切除.

左邊的那片是銀的, 右邊是pewter (錫與鉛、黃銅等的合金)
銀的熔點及硬度比pewter 高.
但它的顏色亮度很相近.
I casted both pieces.
I casted sterling silver on the left.
Pewter on the right.
Bright and shine.
A figure. 一個女人的曲線.
This is my favorite piece.
我很喜歡這件作品.
Little sculpture_Moon
unexpected result.
雖然是失敗的作品,但是卻意外的成為一件小雕塑作品.
一個小月亮. 我還蠻喜歡的.
