Chii Chinonzi Crystalline Glazes?

Crystalline glazes ndeyezvipfeko zvinotarisa zvinoratidzika zvakajeka uye zvakajeka kukura kwekristasi mumatrikisi emagetsi anoputika. Kunyange zvazvo makristani akawanda haasi aya makuru, mamwe anokwanisa kukura kusvika mana kana mashanu mucheka mukati mechiratidzo che glaze.

  Makristori muGlazes

  Invisible makristasi anogara mune dzakawanda kana kwete yakawanda. Mune matte glaze mavara uye mazhizha anogadzirwa nemigumisiro ndiwo matambudziko emarudzi akawanda emakriststals kana makristasi ari maduku zvokuti haaoneki kune ziso rakashama. Iko macro-crystalline glazes, kana inowanzozivikanwa sekristalline glazes, ine makristasi anokura akakwana zvakakwana kuti aone.

  Iyo inopisa pamubhedha unoputika kazhinji inonzi amorphous supercooled liquid. Sezvo glaze yakanyauka uye yakanyoroveswa mumoto , magirasikoro akabatanidzwa pamwe chete mumakumbo asina kumira. Mvere dzinoitika kana iyo inotonhora inotonhorera zvakakwana kubvumira mamolekyu kuti awedzere uye anopisa zvakaringana kwenguva yakakwana kubvumira mhepo dzemazaya kuti dzizvigadzirire pachavo mumakumbo akaumbwa, kana makriststals.

  Mavhenekeri Anooneka Sei Form

  I-macro-crystals inowanikwa mu crystalline glazes fomu yakakomberedza nucleus yediki duku titanium oxide kana zinc oxide crystal. Mumamiriro ezvinhu akanaka, zinc uye silica oxide molecules dzichatanga kuzvibatanidza pachavo kune nucleus crystal. Izvi zvikwata zvemakemikari zviri mumarongwa chaiwo, izvo zvatinoona semakristasi.

  Kuti izvi zviitike, panofanira kuva nenguva yakareba pamatambo ekudzivirira kuti zvibvumire nguva yekristini kukura, uye glaze inofanira kuva neyakanaka yemakemikari. Iyi ndiyo yekutanga yezvinhu zvitatu izvo zvinyorwa zvinogadzirisa nazvo pazvinoshanda nekristalline glazes.

  The Firing Schedule

  Mvere dzinotora nguva yakareba kuti dzikure. Kuti izvi zviitike, girazi inofanira kuramba yakanyungudutswa kwenguva yakareba. Kupinza zvirongwa zvekristalline glazes kazhinji zvinoda nguva yekudonhera pamagumo ekuwana kwekushisa, pamwe chete nechepasi-kudhonza .

  Kazhinji, makristuru anotanga kuumbwa senhengo dzesinga-dzakafanana munenge 2084 F (1140 C). Kana kutonhora kuchiitwa munenge muna 2012 F (1100 C), chimiro chechipiri-axehead chinowanzomuumba. Kubata kutonhora kubva muna 1994-1850 F (1090-1010 C) kunokurudzira chimiro chekufamba. Makristasi akazara akazara akapa maruva-akafanana.

  The Chemical Glaze Composition

  Kazhinji, crystalline glazes inowedzera-moto inopenya uye inoda kuti zvidimbu zvikamu zvezinc, titanium, kana lithiamu. Lithium inokwanisa kukurudzira kristini kukura kunyange mumusana wekushisa.

  Crystalline glazes yakaderera kupfuura yakasarudzwa mu-alumina yavo. Mukuwedzera, chiyero chemahara silica mumasikati maviri uye muviri wevhu unofanira kuchengetwa kusvika padiki. Kana zvisina kudaro, cristobalite inogona kuumba, ichiita kuti pombi iwedzere kunetseka uye inotanga kutyisa.

  Nemhaka yezvinodiwa izvi, crystalline glazes inowanzova yakasimba. Ikoti inofanira kubudiswa pamusana webhisiki-saucer (ona mufananidzo) kubata zvose zvinodonha. Pasi yehari yacho inogona kuve yakasvibiswa uye yakasvibiswa mushure mokunge yabviswa kubva mumoto.

  Glaze uye Crystal Coloration

  Nemhaka yekristol's molecular structure, vamwe vevarai chete vanogona kupinda uye vagozora kristall. Aya ndiwo cobalt, nickel, mhangura, iron, uye manganese. Zvisinei, zvichienderana nemakemikari maitiro, mavara aya haasi ose anoita nenzira imwechete.

  Cobalt ndiye ane simba; iyo inokunda kukwezva kwevamwe mavarai uye inopinda mukati mekristini chimiro chega. Somuenzaniso, kana cobalt uye manganese zvose zviripo, cobalt inopinda mumakristasi achiiita bhuruu, uye ma manganese acharamba ari mumatrix, zvichiita kuti iite. Kana cobalt isipo, nickel inotora mberi inotanga kupinda mumakristini, zvino manganese, ipapo mhangura. Mhangura, kana iga yoga, ichapenya glaze uye kriststal zvakarurama.
