PROOF OF CAST GRANITE CASING STONES ON THE SPHINX TEMPLE
IN GEOLIGY Granite forms deep, slow, and under pressure — so gases can’t form bubbles. Rocks that form fast and at the surface (like pumice) do get bubbles.
That’s a great question — and it touches on how granite forms and what it’s made of.
Here’s the key idea: You can’t get air bubbles in granite because granite forms deep underground from slowly cooled molten rock (magma), under high pressure, where there is no air.
Let’s break that down:
1. Granite forms underground (intrusive igneous rock)
Granite crystallizes slowly as magma cools beneath the Earth’s surface.
Because it cools so slowly, gas bubbles (if any) have time to escape before the rock solidifies.
2. High pressure environment
Deep underground, the pressure is immense.
Any gas dissolved in the magma is kept in solution — it doesn’t expand into bubbles like it would near the surface.
3. No air underground
There’s no "air" (like oxygen or nitrogen gas) in the magma chamber.
The only gases present are volcanic gases (water vapor, CO₂, SO₂, etc.), and under those pressures, they stay dissolved.
4. Contrast with extrusive rocks (like pumice or basalt)
When magma erupts at the surface (as lava), the pressure drops suddenly.
Dissolved gases expand and form bubbles, which can get trapped as the lava solidifies — that’s why rocks like pumice or scoria have vesicles (gas bubble holes).
OR THIS IS WHAT IS REALLY GOING ON
💨 1. Entrapped air during casting
When liquid or semi-liquid granite mixture is poured into a mold, air can get trapped if the mix isn’t properly vibrated or degassed.
If vibration or vacuuming is insufficient, small pockets of air remain.
Once the mix hardens, those trapped bubbles become voids or “blowholes.”
Over time, if the surface layer weathers or chips away, one of those voids can become exposed — just like what you’re seeing in your photo.
🧪 2. Resin or cement shrinkage
If resin or cement binder was used, shrinkage during curing can pull the material away from the aggregate in certain spots, creating hollow areas that look like air bubbles.
🔥 3. Thermal or chemical breakdown
If the casting was exposed to heat or weathering, differences in expansion between the binder and the granite pieces can cause debonding, which can enlarge a small void into the cavity you now see.
🧱 4. Appearance of a “bubble”
The smooth, concave inner surface is typical of a void formed around a trapped air pocket, not of natural granite crystallization. It looks like a popped bubble because that’s literally what it was — air that couldn’t escape before the material set.
So in short:
The “air bubble” is a casting defect — trapped air or gas within the poured granite mix that became sealed inside, then later exposed when the surface layer cracked or eroded. That “air bubble” makes perfect sense once you remember how cast granite is made. When crushed granite, binder (like resin or geopolymer), and pigment are mixed and poured into a mold, the mixture traps tiny pockets of air.
If the mix isn’t vibrated or vacuum-degassed properly, those bubbles can’t escape. As the material cures, those trapped pockets stay sealed inside. Later, when the surface wears down, chips, or is cut through, one of those voids can suddenly appear — exactly like the one in your photow.
