KESALAHAN CASTING

Kemungkinan akan terjadi kesalahan atau kerusakan pada hasil Casting. Untuk mengatasinya dilakukan penyesuaian atau perubahan. Disini saya mencoba untuk memberikan solusinya untuk mengatasinya.

Susah mengalir : Terlalu lama untuk mengisi cetakan. Disebabkan terlalu kental.

Solusi : Tambahkan air atau tambahkan deflocculant ( Water Glass )

Susah mengeras : Bila keluar dari Continue reading

CARA MENCEGAH PENCUCIAN KIDNEY (DIALYSIS)

Sebetulnya ini agak nyleneh (janggal) diletakkan di web ini. Tapi karena teman saya email, dan Papa saya juga pernah cuci darah sampai meninggal, jadi saya tertarik untuk menempatkan di web saya, kalau kalau ada yang membutuhkan. Ini adalah copas ( copy paste ) dari email aslinya.

Dear all,
Saya Saragih) dapat email dari teman mengenai cara untuk mencegah “cuci buah
pinggang” untuk mereka yang masih baru kena penyakit kidney. Manatahu bermanfaat. Continue reading

Analisa bahan perlu untuk penghitungan bila beberapa bahan digabung menjadi campuran bahan ( komposisi )  bahan keramik, selain plastisitas, penyusutan bahan.  Sebab bahan baru tidak bisa dicampurkan begitu mudah, karena bila tidak tepat akan mengalami crazing ( retak seribu), shivering ( glasir mengelupas), crowling ( kalis), de el el.

Clay, the Driying and Firing proses
Many potters, especially beginners, use prepared clays without much thought. However, there comes a point when it is useful to understand the process that clay goes through during drying and firing. This can help troubleshoot many of the problems you experience with your pieces. Plus it is darn interesting!
Air Drying
Wet clay contains a large amount of water, a minimum of 25% water. When clay starts to dry, water evaporates from it. As this happens, the particles of clay are drawn closer together resulting in shrinkage. Many problems with clay are formed by uneven rates of drying, which create stresses in the clay. Sometimes these stress show up right away as cracks or warpage, other times not until during or even after firing. So it is important to ensure drying is even. This is done by ensuring uniform thicknesses throughout the piece, drying slowly, and even slowing down the drying of certain parts. This has been discussed in several previous tips.

RAW MATERIALS


RAW CLAYS
The theoretical formula for clay is Al2O3 2SiO2 2H2O, an alumina-silicate, but none are that pure and uncontaminated. There are many technical characteristics that define a material as a clay but, for ceramics, the primary characteristic beyond the alumina and silica content is the fact that they are composed of very small flat platelids with a resulting very large surface area with microscopic water between them so they slide on one another and additionally tend to hold their shape. Additional properties of clays are 1) harden when dried and become permanent when fired, 2) shrink during drying and firing, 3) refractory (resist softening at high temperature), 4) heat, sound and electrical insulation.
