1. Ga shadawn hku nna: 6, 7, 8, 9, 10, 12, 15, 18, hte 20 mm galu ai hku nna lu mai ai.
2. Glass arung arai hku nna:
Sodium glass (sh) limestone glass): Ndai zawn re ai glass gaw n-gun n rawng ai majaw, hka lim ai shara hta n-gun n rawng ai sha, n-gun n rawng ai (weathering) byin chye ai. N-gun n kaja ai majaw, loi loi hte daw mat chye ai. Miwa mung hta lang ai glass hta 80% daram gaw ndai zawn re ai glass ni rai nga ai.
Lead glass (red lead glass ngu nna mung shamying ai): Shi a n-gun, jak rung, wan n-gun, tsi mawan ni hta n-gun n rawng ai, n-gun n rawng ai, nhtoi htoi ai atsam ni gaw sodium glass hta grau kaja ai. Shi a nbung laru hpe ninghkap lu ai atsam hte service prat gaw sodium glass hta grau ai. Mungkan ting hta, lead glass hpe grau nna lang ai tubing amyu langai mi rai nga ai. Miwa mung hta gaw, shi hpe jai lang ai lam gaw 20-30% daram du sai. Hpaga galaw ai ni hte quality tsaw ai hpe tam ai ni gaw neon nhtoi a matu lead glass hpe law law lang lata ma ai. Lead glass hpe lead rawng ai hku nna matut nna garan ginhka ai: n-gun ja ai lead glass, lapran tsang lead glass, n-gun n law ai lead glass.
Nsam rawng ai shingnip shingna: Ndai shingnip ni hpe sumla ka ai shaloi, nsam rawng ai shingnip shingna langai mi pru wa ai.
3. Neon hka htung ni a kata maga hpe ka-up na matu lang ai phosphor arung arai hku nna garan ginhka ai:
Neon tube law malawng hpe "ordinary phosphor" hte ka-up da ai, dai gaw manu n-htuk ai hte, nsam amyu myu ra kadawn ai lam ni hpe mung, madung hku nna hkap la lu ai.
"Tri-color" phosphor (rare-earth phosphor ngu nna mung shamying ai) gaw, shinggyim masha ni lang ai phosphor hte shingdaw yang, grau kaja ai nhtoi, chroma, hte nsam nsam ni hpe mu lu ai.
4. Phoshor coating galaw ai ladat hpe hka- hpe madung tawn ai coating hte adhesive coating ngu nna lahkawng hku garan nna galaw ai.
Hka- hpe madung tawn ai coating hta, phosphor hpe alcohol (sh) ketone solvents hte kayau nna, hka htung kata na bunghku ntsa de chya nna, shingra tara hku hkyet mat hkra galaw ai.
Adhesive coating ngu ai hta, phosphor hpe adhesive hte kayau nna, hka garan nna, wan wut hta hkyet kau ai. Shi a viscosity hte fastness gaw hka- hpe madung tawn ai coating hta grau kaja ai hpe mu lu ai.
