; Naming
; Naming
Wery named it "frost" because:
Lucite is another name for acrylic glass.
* Musically, it sounds like frosted glass (perhaps to do with the [[timbre]]/[[partial]]s of struck glass)
 
* It is close to [[ripple]][23], but turned inside out, so just as ice is water in an altered state, frost is ripple in an altered state
Wery named the temperament "lucite" because musically, it sounds like frosted glass (perhaps to do with the timbre/partials of struck glass).
 
Some coincidences that make the name "lucite" particularly fitting
* Lucite is often installed in double layers in building, and lucite temperament has two sizes of perfect fifth-like interval.
* Lucite[23] is close to ripple[23], but turned inside out; and lucite is reflective and clear like water, but solid instead of liquid
* Lucite is an especially lightweight material, and lucite temperament is lightweight in the way it only needs 18 generators to reach every 17-limit prime.

=== 34.3edo ===
'''34.3edo''' is contained within 343edo (it is every 10th step of 343edo). It is like [[34edo]] with the [[octave shrinking|octave compressed]] by 11.51 [[cents]].
It has a step size of 34.985{{c}}.
It was discovered by chaseofspades513 and [[YoVariable]] on the [[Xenharmonic Alliance]] Discord server and further described by [[Gordon Wery]].
Compared to 34edo it improves harmonics 7, 11 and 13, at the expense of 2, 3 and 5. Its mappings of multiple-of-2 and multiple-of-3 harmonics are very inconsistent, though some composers may enjoy this due to the potential to play tricks on the listener by having [[octave equivalence]] fall on a scale step one might not expect.
Many temperaments and [[34edo#Scales|scales from 34edo]] can be used here in 34.3edo too.
