Ukukhupha uboya: umbala wombala ohlaza okwesibhakabhaka wedayi kunye nokwenza isepha

Ukwenza eyakho idayi eluhlaza okwesibhakabhaka

Ukukhula nokukhupha i-pigment eluhlaza okwesibhakabhaka kwi-Isatis tinctoria, eyaziwa njenge Woad. Ekhutshiwe kumagqabi aluhlaza, lo mbala wendalo usetyenziselwa ukudaya nokwenza isepha

Ukuvela kwii-steppes ze-Asia esembindini, iWoad, ekwabizwa ngegama lesiLatin elithi Isatis Tinctoria, iye yalinywa kulo lonke IYurophu neMeditera kangangeenkulungwane . Nangona imbewu yayo ifunyenwe kwiziza zaseFransi zeNeolithic, ubungqina bokuqala bokuba isetyenzisiwe kwidayini yelaphu ivela kwi-Egypt yamandulo. Ubungqina bamva kweedayi zeWoad zivela kwimithombo yamaRoma, iViking kunye namaxesha aphakathi kunye neziza.

Ukuba ndakhe ndadibana nabani na ongaqhelananga nesi sityalo ndihlala ndibathumela kwiBraveheart phantse wonke umntu ombonileyo. Nje ukuba ndikhankanye uMel Gibson epeyinta ubuso bakhe obuhlaza okwesibhakabhaka ithanda ukutshintsha iswitshi ebantwini, nangona kukho impikiswano malunga nokuba amaBritane akhe asebenzisa iWoad ngale njongo.

Ukufakela amaqabunga e-woad emanzini malunga ne-80 degrees Celcius

Kunzima ukukholelwa ukuba la magqabi aluhlaza acacileyo aqulathe ibala eliluhlaza ocacileyo kwaye ndiyazibuza ukuba abantu bokuqala bayifumene njani. Uninzi lwezinto zethu zakudala ezifunyenweyo zibonakala ngathi zenzekile ngengozi kwaye andithandabuzi ukuba bekunjalo ngeWoad. Nangona kunjalo kunamanyathelo ambalwa kwinkqubo yokukhupha endenza ndizibuze ukuba ingaba umntu angakhubeka njani apha emhlabeni.

Ukukhupha iWoad kufuneka uqale ngokufaka amagqabi kumanzi abilayo phantse-amanzi athambileyo njengamanzi emvula. Emva kwemizuzu elishumi amagqabi ayasuswa kwaye axinwe nasiphi na ijusi ngaphambi kokuba alahlwe kwingqumba yomgquba. Ulwelo olubangelwayo luxinekile emva koko kongezwa i-ash ash eqala inkqubo yokukhupha. Isoda ash luhlobo lwe-carbonic acid olunokufunyanwa kuthuthu lweentlobo ezahlukeneyo zezityalo - ikwasetyenziswa njengesixhobo sokuthambisa amanzi. Ngenkqubo yomoya, ukulungisa, ukuhlamba, ukuhluza kunye nokomisa ushiye ngombala wendalo ohlaza okwesibhakabhaka onokugcinwa kwaye usetyenziswe ngokungenammiselo. Ngolwazi oluthe kratya malunga nenkqubo nceda undwendwele Woad.org.co.uk .

Ukunyanzeliswa kokufakwa kunye nomxube

Ukuvumela i-pigment ukuba ihlale kulwelo

Kutshanje ndiye ndadibana nabantu abambalwa abaye bandibuza malunga nokusetyenziswa kwe-woad kulusu kunye nokuba ikhuselekile na. Impendulo yam kukuba iWoad yimveliso yendalo engenabungozi kwaye ikhuselekile ngokupheleleyo ukuphatha nokuyisebenzisa ngaphandle. Ngapha koko usokhemisti owayeqhuba uvavanyo lokhuselo kwiimveliso zam eneneni undivumela ukuba ndisebenzise ngaphezu kwesihlandlo esiphindwe kalishumi isixa sesepha yam esiqulathe oko.

Uboya bunokuba njalo ithathwe ngaphakathi , nangona ndingazange ndizame mna. Isetyenziswa kumayeza esintu aseYurophu nawaseTshayina ubuncinci iminyaka engamawaka amabini, iikhompawundi eWoad kuthiwa zilwa neentlobo ezithile zomhlaza kunye nezifo ezichasayo. Izifundo zabantu ezivela e-China zikwabonakalisile ukuba i-Woad ineempawu zokulwa i-antimicrobial, antibacterial, antiviral kunye ne-antiparastic. [ 1 ]

Kukwakho nolunye ulwazi olungelulo kwi-intanethi malunga nokuba iWoad iyakungcolisa ulusu lwakho. Ndingawucinga umsebenzi wokutsala kule ngcinga: Kuba iWoad isetyenziselwa ukudaya amalaphu ayinakuphinda ifake umbala kuyo nayiphi na enye into edibana nayo? Ndingathanda ukukuqinisekisa ukuba uboya njengombala womgubo imibala yesepha kuphela. Isebenza ngendlela efanayo ne-pigment yamaminerali kwaye iyanqumamisa njengama-granules amancinci kuphela anika inkohliso yokudaya isepha. Ukuze kusetyenziswe uboya njengedayi, iikhemikhali ezongezelelweyo ezinje ngeAlum kunye neSpectralite ziyafuneka ukuze ‘zilungise’ kwilaphu okanye kuboya.

Elinye inqaku elilungileyo kwi-woad kukuba iyaphula ngokulula ngakumbi nangokwemvelo kunee-oksidi zentengiso. Le propati yenza le mveliso ibe yenye indlela enovakalelo lokusingqongileyo kwii-micas, ii-oksidi kunye nezinye izinto ezenzelwe ilabhoratri.

Ngamafutshane, iWoad ikhuselekile, ayizukulonakalisa ulusu lwakho kwaye iyathandeka kwaye iyinyani yendalo yokusetyenziswa kweesepha. Ndiyakonwabela ukuyisebenzisa kwaye ndiyikhulise egadini yam kwaye ndingakhuthaza nabani na onomdla kwiWoad ukuba ayizame nayo.
