Topic

Other / unclassifiable — a classification, not a measurement. An on-box language model (Qwen3.6-35B-A3B-FP8, prompt version 1) read this channel’s own recent posts on 27 September 2026 and assigned it the closest of 31 fixed categories, at 95% confidence. This is a model’s judgement about what the channel is likely to be about, not a fact this register measured the way a subscriber count or a view count is measured — it can be revised on a later pass, and it carries no weight anywhere else on this page. How this classification works, and why it has no browse page of its own yet.

7 measurements spanning 49 days, net +4. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 83–90 and does not start at zero.

Engagement

19 posts held, back to 2 February 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 19 posts for this entry, the most recent from 15 July 2026. An engagement rate over an empty window would be a number about nothing.

What this channel posts

Measured directly from 2 videos with a duration reading, out of the posts we hold for this channel — not this channel’s whole posting history, only the sample this register has actually read. An exact reading to the second, taken from the post itself rather than from Telegram’s own rounded chrome, so it carries no ≈ mark.

Reaction mix

92 reactions across 19 posts, in 3 distinct kinds. The most used accounts for 56.5% of them.

Every reaction kind recorded on the sample, most used first

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 19 of the 19 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 92 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 19 most recent posts we hold, published 2 February 2026 to 15 July 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

🧱 Annealed, Tempered or Laminated Glass — which one do you need? 🔹 Annealed — easy to cut, breaks into sharp shards. Best for interiors or further processing. 🔹 Tempered — 4–5x stronger, shatters into small safe fragments. Ideal for façades, doors, structural use. 🔹 Laminated — holds together when broken. Go-to for safety, security, and sound insulation.

Glass is a unique material that is transparent, yet can appear colorful depending on the light and the angle of refraction.

❔Did you know how PDLC technology works? The magic of PDLC Smart Glass lies in its unique construction. It typically consists of a PDLC film, which is a thin layer of liquid crystal droplets dispersed within a polymer matrix, sandwiched between two layers of conductive material (like ITO – Indium Tin Oxide) and then laminated between two panes of glass. ✨An ideal solution for offices, meeting rooms, bathrooms, vehi…

Showing the 12 most recent of 19 posts we hold for @glassopenbook. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
