1. Long sais: I gat ol 'thickness' bilong 6, 7, 8, 9, 10, 12, 15, 18, na 20 mm.
2. Long glas samting:
Sodium glass (o limestone glass): Dispela kain glass i no save stap gut na i save bagarap na i save kamap bikpela taim em i stap long ples we wara i stap long en. Em i no gat strong na em i save bruk isi. Klostu 80% bilong ol glas we ol i save yusim long Saina em i dispela kain glas.
2Lead glass (ol i save kolim tu olsem retpela lead glass): Ol samting bilong en i gutpela moa long 'thermal', 'mechanical', 'electrical', 'chemical stability', 'vacuum performance', na 'optical properties' winim 'sodium glass'. Strong bilong en long taim bilong san na sevis laip bilong en i winim tru bilong sodium glas. Long wol, 'lead glass' em i nambawan kain 'tubing' we ol i save yusim. Long Saina, yusim bilong en i kamap klostu long 20-30%. Ol kampani na ol manmeri husat i laikim gutpela kwaliti i save makim 'lead glass' bilong wokim ol neon lait. Ol i save tilim 'lead glass' long 'lead content' bilong en: hevi 'lead glass', namel 'lead glass', na 'light lead glass'.
Ol glas paip i gat kala: Ol i save pulimapim ol dispela paip wantaim kala taim ol i droim piksa, na dispela i kamapim wanpela glas paip i gat kala.
3. Klasifikasen long ol samting bilong 'phosphor' we ol i yusim long karamapim insait bilong ol 'neon tube':
Planti ol 'neon tube' i gat "ordinary phosphor" long en, we i no gat bikpela pe na i save inapim ol kain kain kala.
"Tri-kala" fosfora (ol i save kolim tu olsem 'rare-earth phosphor) i gat gutpela lait, 'chroma', na 'vividness' moa long nomol fosfora.
4. Wok bilong putim 'phosphor coating' i bruk long tupela kain: 'water-coating' na 'adhesive coating'.
1Wata-koting em i miksim 'phosphor' wantaim 'alcohol' o 'ketone solvents' na spreim i go insait long wol bilong 'tube', na larim em i drai stret.
2Adhesive coating em i wok bilong miksim 'phosphor' wantaim 'adhesive' na spreim, na draim long aven. Viskositi na strong bilong en i gutpela moa long wara-koting.
