  2. June 19 IRC logs: "P6:36:49 <Fishlips> loving the new glass" (23:36 UTC)
  3. June 19 IRC logs: "P5:59:14 <Notch> I might just revert the glass to the horrible non-transparent texture from the screenshot" [...] "P5:59:49 <Evil-Ville> I actually liked the old glass more Notch" [...] "P6:19:32 <Notch> I'm switching glass to a non-semi-trasparent texture" [...] "P6:25:51 <Redshift> yeah windows definitely need to be less opaque, personally i think they should have no texture, and just a slight hint of opacity" (22:59 to 23:25 UTC) | "the screenshot" refers to "Glass (looks pretty bad..) and sponge!" – Notch, June 16, 2009, Tumblr | The opaque glass texture refers to the Glass JE1.jpg 0.0.19a texture.
  4. June 22 IRC logs: P1:17:31 <Haruhi2> the version that was semi-opaque looked more like ice than glass [...] then the version after that was fine [...] then he changed it a bit and now it doesn't really look like either
  5. June 19 IRC logs: P6:18:11 <Notch> should I take out the random vanish? [...] consider it done
  6. June 19 IRC logs: P6:00:40 <liq3> OH I see. Make sure thehre's a level of water above both sponges and it'll flood the remaining one. [...] Notch: You going to be able to hotfix it? [...] P6:02:10 <Notch> maybe..
