2. Ɛdenam ahwehwɛ nneɛma so:
1 Sodium ahwehwɛ (anaasɛ limestone ahwehwɛ): Saa ahwehwɛ yi ntumi nnyina yiye na sɛ ɛba nsu mu a, ɛtaa sɛe na ɛyɛ frɔmfrɔm (wim tebea a ɛyɛ mmerɛw). Ɛwɔ ahoɔden a enye na ɛnyɛ den sɛ ebebubu. Ahwehwɛ a wɔde di dwuma wɔ China no bɛyɛ 80% na ɛyɛ saa.
2 Lead glass (a wɔsan frɛ no red lead glass): Ne hyew, mfiri, anyinam ahoɔden, nnuru a egyina pintinn, vacuum adwumayɛ, ne aniwa su no korɔn sen sodium ahwehwɛ. Ne wim tebea a ɛko tia ne ne nkwa nna boro sodium ahwehwɛ de so koraa. Wɔ amanaman ntam no, kɔbere ahwehwɛ ne nsukorade a wɔtaa de di dwuma sen biara. Wɔ China no, ne dwumadie adu bɛyɛ 20-30%. Wɔn a wɔyɛ ne wɔn a wɔde di dwuma a wɔhwehwɛ nea ɛkorɔn no taa paw kɔbere ahwehwɛ ma neon akanea. Wɔsan kyekyɛ kɔbere ahwehwɛ mu sɛnea kɔbere a ɛwom te: kɔbere ahwehwɛ a emu yɛ duru, kɔbere ahwehwɛ a ɛwɔ mfinimfini, ne kɔbere ahwehwɛ a emu yɛ hare.
3 Ahwehwɛ nsukorade a ɛwɔ kɔla: Wɔde aduru hyɛ saa nsukorabea yi ma bere a wɔreyɛ mfonini no, na ɛma wonya ahwehwɛ nsukorade a ɛwɔ kɔla.
3. Nkyekyɛmu denam phosphor ade a wɔde kata neon nsukorabea no mu so:
1 Wɔde "phosphor a ɛyɛ mmerɛw" a ne bo nyɛ den koraa na mpɛn pii no edi kɔla ahorow a wɔhwehwɛ ho dwuma akata neon nsukorade dodow no ara so.
2 "Tri-kɔla" phosphor (a wɔsan frɛ no rare-asase phosphor) wɔ hann, chroma, ne pefeeyɛ a eye sen phosphor a ɛyɛ mpapahwekwa.
4. Wɔakyekyɛ phosphor a wɔde kata so no mu abien: nsu-a wɔde kata so ne ade a wɔde kata so.
1 Nsu-a wɔde kata so no hwehwɛ sɛ wɔde phosphor fra nsa anaa ketone aduru na wɔde petepete afiri no mu fasu so, na ɛma ɛyow wɔ abɔde mu.
2 Nea ɛka adhesive coating ho ne sɛ wɔde phosphor fra adhesive mu na wɔde petepete so, afei wɔma ɛyow wɔ fononoo mu. Ne viscosity ne fastness ye kɛse sen nsu-based coating.
