Can I Dissolve Through Tempered Glass?

I test to see if I can successfully make a hole in tempered glass without shattering it by using chemicals instead of abrasives.

  • It might have worked if etching had continued from one side, rather than flipping it. That would have removed the sensitive tensile center while it was still supported by the compressive layer on the bottom. By flipping and removing both outer compressive layers, only the tensile center was left, getting thinner and thinner. It’s hard to imagine any conclusion where the thin membrane under tension doesn’t crack. Therefore, etch all from one side, so the final membrane is under compression instead.

  • Quick research shows that it is also possible to anneal tempered glass, drill your holes, and then re-temper it. properly tempering glass is very difficult for the homegamer, however.

  • This one is interesting to me. I work in a glass factory, currently laminating wind shields but spent years tempering for back lites and sun roofs. I used to get sprayed with glass cullet when they would break while quenching. And throwing away rejects / testing we broke many thousands of pieces. Can be satisfying stress relief sometimes

  • Inside a piece of tempered glass, it's the central layer that is being pulled. When you dissolve through the central layer to weaken it enough, it could no longer hold the pulling tension and caused the explosion. From this perspective I would say there is no way to cut apart the central layer of a piece of tempered glass due to the pulling tension on it.

  • what if you continued on the same side?- the way it was done, the last piece of glass still intact was under tension- perhaps doing it the other way around would have made it more stable, dissolving away the compressed glass last

  • This ain't rocket science, glass is heated to cherry red . Then the glass is extruded from the oven , jets of cold air cool the two surfaces the center of the glass is still molten. When the core cools , you have a potential spring . Any crack that goes to the center of of the thickness of the glass, causes the entire sheet to fracture. The number in the corner of side window glass in your car is the number of pieces you get when you break it. That's what DOT 50 means , a 6 square centimeter piece of tempered glass will break into 50 piece.

  • thats pretty interesting, in fact i wonder if we could estimate the tempering-stresses based on the initial and end-thickness. since the process is so slow, you find exactly the thickness where the static equilibrium of forces cannot be fulfilled anymore because the tensile strength got exceeded.... :)

  • Is HF that dangerous? It really only dissolves two things - glass and people! So yes it is very dangerous! If you get it in your skin it moves into you and finds your bones. It reacts with the hydroxy apatite crystals in you bones which then forms a fluoridated crystal structure that is bigger. The crystals now do not fit together properly weakening the bone and causing considerable bone pain.

    Dean HaynesDean HaynesÅr sedan
  • I say try again, but balance the glass, give it feet around the spot you want to make the hole and feet on the corners. It's a possibility that the acid weakened the glass enough, that pane's own weight shattered it and the removal of the pane from the bin may have caused a mound or two in that powder to unbalance it. Just a thought...

  • Hey what if you found a way to stabilize the tension around the area you are dissolving? I'm not an expert but if you want to put a needle through a baloon, you put tape on it, and get the needle through without popping the baloon so long as the tape is on there. Is there anything similar for tempered glass? Like some epoxy you can vaporize through the glass in an area? I don't know what I'm talking about but curious.

  • Ehhh... If you heat the piece of glass in an oven while it does this, is that cheating? At any rate, you need a way to relieve the stresses in the glass before inducing them again to resume the strength of the tempered glass. You can do that by immersing it in a bath of heated, concentrated salts. The commercial example is a beer bottle, which is soaked in a solution of magnesium sulfate to leech out the sodium and potassium hydroxide from the glass. They do this for reasons beyond altering the glass strength (it prevents the alcohol in the beer from reacting with the glass and throwing an off flavor), but it does make beer bottles stronger than non-ion exchanged bottles. Ions of smaller atomic radii can diffuse into the glass more readily than large ions. Lithium is good at this, but it causes brittleness and hardening in the glass after the fact. The lithium ion is probably too small for most things. Boric acid can induce stresses into glass, but i don't know how controlled it is. It also increases the melting point of the glass, in case that matters. All alkaline salts, like potassium or sodium hydroxide react directly with glass too. If you can get the glass and sodium hydroxide hot enough, you could just drop molten sodium hydroxide onto it and it'd eat through it, but it'd still probably explode at that point. Any who....
