Does sodium hydroxide etch glass?

NaOH was more reactive than KOH with E-glass fibres; at times we found NaOH to etch glass fibres up to twice the magnitude of KOH. Increasing the concentration and temperature of the alkaline solution resulted in an increase in the reaction rate.

Does NaOH damage glass?

Sodium hydroxide slowly reacts with glass to form sodium silicate, so glass joints and stopcocks exposed to NaOH have a tendency to “freeze”. Flasks and glass-lined chemical reactors are damaged by long exposure to hot sodium hydroxide, and the glass becomes frosted.

What chemicals will etch glass?

A chemical etching spray (typically hydrofluoric acid) dissolves unprotected glass areas to etch the desired image. The resist is then selectively removed, exposing the etched pattern on the glass.

What is the acid used to etch glass?

hydrofluoric acid
The object is then immersed in hydrofluoric acid, or a mixture of dilute hydrofluoric acid and potassium fluoride is applied to etch the exposed areas of glass.

What chemical can dissolve glass?

Hydrofluoric acid
3.3. Hydrofluoric acid is a solution of hydrogen fluoride (HF) in water and is a precursor to almost all fluorine compounds. It is a colorless solution that is highly corrosive, capable of dissolving many materials, especially oxide and its ability to dissolve glass has been known since the 17th century.

Why should NaOH not be stored in glass bottles?

NaOH reacts with the CO2 present in the air over the solution inside the bottle.

Does muriatic acid etch glass?

Typically, products containing muriatic acid or phosphoric acid are best for removing hard water stains from glass. However, while the acids in oven cleaner will remove the stains, they can also dissolve the paint or glazing around a window—which is probably something you want to avoid.

Will hydrofluoric acid etch glass?

From Wikipedia on hydrogen fluoride: “Although hydrofluoric acid is regarded as a weak acid, it is very corrosive, even attacking glass when hydrated.” On hydrofuoric acid: It etches glass “by reacting with silicon dioxide to form gaseous or water-soluble silicon fluorides. “
