			<content:encoded><![CDATA[<p><strong>How to pour the liquid / slurry into the ceramic mold</strong></p>
<p>Sebelum anda menuang cairan/bubur keramik kedalam cetakan gypsum, periksa dulu cairan dangan terlalu encer atau terlalu kental. Cara mengukur bisa anda lihat <a href="http://keramik88.com/ceramic-problems/how-to-test-your-slip.html">disini</a></p>
<p><a href="http://keramik88.com/wp-content/uploads/2011/10/menuang-cairan-bahan-keramik.jpg"><img class="size-full wp-image-3157 alignleft" title="menuang cairan bahan keramik" src="http://keramik88.com/wp-content/uploads/2011/10/menuang-cairan-bahan-keramik.jpg" alt="" width="145" height="220" /></a></p>
<p>&nbsp;</p>
<p>Setelah memenuhi syarat yang di anjurkan, siapkan cetakan, buka belahan cetakan satu persatu, bersihkan sisa-sisa bahan yang kering bekas cetakan sebelumnya dengan menggunakan kuas, lebih baik lagi bila anda menggunakan semprotan angin dari compressor.</p>
<p>Bila tidak bersih, bahan sisa yang kering akan menempel dan masuk di hasil cetakan yang baru, mengakibatkan terpisahnya bahan kering dengan bahan yang baru dicetak, akan memisah menimbulkan retak, sehingga tidak bisa dipakai.</p>
<p>Setelah bersih, pasang kembali belahan cetakan menjadi satu, diikat dengan ban dalam bekas mobil, yang digunting selebar 1-2 cm, tergantung besar kecilnya cetakan yang digunakan. Pastikan karet pengikat benar kuat, karena bila tidak tekanan dari cairan keramik akan mendesak keluar, cairan/bubur akan keluar melalui celah cetakan.<span id="more-3156"></span></p>
<p>Gambar diambil dari http://www.caribicdesign.com/process.php</p>
<p>Sekarang anda bisa mulai menuang cairan/bubur keramik . Tuang perlahan jangan berhenti  jika belum penuh. Karena bila anda berhenti ditengah, aka nada garis melingkar pemisah, terutama bila cairan yang anda gunakan terlalu kental.</p>
<p>Tunggu 10-25 menit , tergantung jenis bahan dan viscosity bahan, sampai pada tepi cetakan membentuk lapisan  yang lebih keras, biasanya sekitar 4-6 cm ketebalan, tergantung besar kecilnya cetakan. Semakin besar, harusnya semakin tebal. Semakin tebal, memerlukan waktu yang lebih lama. Saya biasanya menempatkan jam dinding yang agak besar agar mudah dilihat.</p>
<p>Setelah menunggu beberapa waktu sampai ketebalan yang dikehendaki, atau melihat jam dinding dan waktunya untuk menuangkan kembali cairan/bubur keramik  dari dalam cetakan ke tempat tuangan yang berupa saluran menuju sumur pengaduk cairan/bubur.</p>
<p>Tunggu lagi 20-25 menit, tergantung juga bahan yang dipakai, biasanya yang thixotropynya rendah lebih cepat. Bila terlalu cepat, bahan masih lemah/lembek/lunak bentuknya akan berubah dan susah dikeluarkan dari cetakan, kalau terlalu lama akan retak terutama bila cetakan berukir, cetakan cangkir atau teko.</p>
<p>Cetakan yang sudah dipakai 3-4 kali harus dikeringkan, karena sudah mengandung banyak air. Bisa dijemur di panas matahari selama  1-2 hari, atau dibiarkan di suhu ruangan 3-4 hari, atau dengan pengering buatan, asal tidak lebih dari 60 derajat celcius</p>

<em>Casting:</em> Video ini memperlihatkan cara mulai menuangkan cairan/bubur keramik ke dalam cetakan, sampai mengeluarkan dari cetakan. Tahap demi tahap anda akan lebih mudah memahami proses mencetak menggunakan system tuang atau casting.</p>

			<content:encoded><![CDATA[<p><strong>Ceramics<br />
</strong>Originally from the Greek <em>keramos</em> meaning<em> </em>pottery.<br />
Of or relating to the manufacture of, or any product such as earthenware, porcelain, or brick, made essentially from a nonmetallic mineral such as clay, by firing at a high temperature.</p>
<p><strong><br />
Clay<br />
</strong>Clay is the basic material of pottery and has two distinct characteristics &#8211; it can be moulded and it hardens on firing to form a brittle but otherwise virtually indestructible material that is not harmed by any of the corrosive agents that attack metals or organic materials.</p>
<p><strong>Pottery<br />
</strong>Pottery is made of clay and is permanently hardened by firing in a kiln. The nature and type of pottery is determined by the composition of the clay and the way it is prepared, the temperature at which it is fired, and the glaze used. There are three basic types of pottery; Earthenware, Stoneware and Porcelain.</p>
<p><strong>Earthenware<br />
</strong>Earthenware was the first kind of pottery made, dating back about 9,000 years. In the 20th century, it is still widely used. It is pottery that has not been fired to the point of vitrification and is thus slightly porous and coarser than stoneware and porcelain. It is made waterproof by the application of a tin or clear glaze. Nearly all ancient, <span id="more-2754"></span>medieval, Middle Eastern, and European painted ceramics are earthenware, as is a great deal of contemporary household dinnerware.</p>
<p><strong>Stoneware<br />
</strong>Stoneware is pottery which has been fired at a higher temperature than earthenware, such as to partially vitrify the materials and make them impervious to liquids even when unglazed. Stoneware is extremely strong and as it is non-porous and does not require a glaze.</p>
<p><strong>Porcelain<br />
</strong>Porcelain was first made in a primitive form in China, hence its common name <em>china,</em> and is a vitrified pottery with a white, fine-grained body that is usually translucent, as distinguished from earthenware which is porous, opaque, and coarser.  The word porcelain is derived from <em>porcellana,</em> used by Marco Polo to describe the pottery he saw in China. There are three types of porcelain &#8211; Hard Paste, Soft Paste and Bone China.</p>
<p><strong>Bone China<br />
</strong>Bone China is a hard-paste porcelain containing bone ash. The initial development of bone china is attributed to Josiah Spode the Second, who introduced it around 1800. Bone china is stronger than hard-paste porcelain and easier to manufacture. It is strong, does not chip easily, and has an ivory-white appearance.</p>
