Qaybaha ugu muhiimsan ee muraayadaha midabka leh waa ciid quartz oo la safeeyey iyo potassium feldspar, albite, oxide lead (qeybta aasaasiga ah ee galaaska), cusbada (potassium nitrate: KNO3; qaboojinta), biraha alkali, biraha dhulka alkaline (magnesium chloride: MgCl, gargaarka dhalaalidda). , sii kordhinta cimri dhererka), aluminium oxide (kordhinta dhalaalka iyo cimri dhererka kiimikaad) Wakiilada Chromogenic ee midabyo kala duwan (sida cagaarka jaalaha ah ee oxide birta, cagaarka buluuga ah ee naxaasta oxide, iwm) iyo wakiilada caddaynta (arsenic cad, antimony trioxide, nitrate, sulfate). , fluoride, chloride, cerium oxide, ammonium salt, iwm).Muraayadaha Crystal waxa lagu dhalaalin heerkul sare oo ah 1450 ° C, farshaxannada muraayadaha waxaa lagu soo saaraa heerkul hoose oo ah 850 ° C ~ 900 ° C iyada oo loo marayo habka wanaagsan ee dewaxing iyo isku dhafka midabaynta.Ingiriisi, galaas ka kooban isku-dhisyada rasaasta waxaa guud ahaan loo yaqaan crystal ama galaas crystal sababtoo ah gudbintiisa iyo hufnaantiisa, kuwaas oo la mid ah crystals dabiiciga ah.Shiinaha, waxa loo yaqaannaa galaas.Sida nooc ka mid ah galaas crystal midab leh, saamiga xeryahooda sunta rasaasta lagu daray galaas midabka (ka dhigaysa alaabta galaas leeyihiin index refractive sare oo eegi hufan oo dhalaalaya. Hadda, inta badan alaabta loo isticmaalo tuurista ka kooban yahay in ka badan 24%).Qeexitaanadu way ku kala duwan yihiin waddan ilaa waddan, sida 10% Midowga Yurub iyo 24% ~ 40% Czech Republic.Guud ahaan marka loo eego, marka saamiga oxide-ka rasaastu uu gaadho in ka badan 24%, galaasku waxa uu leeyahay gudbin wanaagsan iyo index refractive, sidoo kale waa ka culus yahay oo jilicsan yahay.
Jahwareerka magacyada muraayadaha midabada leh iyo waxyaabaha la xidhiidha ee taariikhda ku jira ayaa horseeday isfaham la'aan iyo isfaham la'aanta muraayadaha midabka leh."Tayle dhalaalaysa" iyo casri "Boshan sameeyey muraayad midab leh" ayaa ah tusaalooyinka ugu cadcad.
