A recent visitor to my site asked:
Hi Eric, I was reading through your site about acid etching, I am looking into doing glass etching by means of hydrofluoric acid, but how ever I am doing alot of research as we all know that this is a dangerous chemical, what I would love to know is the whole process used to get such results, what other chemicals would be required to achieve such results, and what HF percentage is required to achieve this result.
Your assistance is highly appreciated.
My response:
I provide the most basic information about hydrofluoric acid etching and don’t actually use it because sandblasting is a more preferred way for hobbyists. Sandblasting is definitely safer and is the process pretty much dominates this industry today.
That acid is so dangerous that it is known to penetrate through the skin and etch or eat at your bones. The other safe option is to use the chemical cream, but that doesn’t give you professional results or sandcarving effects. Sorry I can’t help you any further with that.
My question for you:
Does anyone reading this post use hydrofluoric acid? It would be great to hear from you and see how many people still use it.

Yes…we use Hydrofloric acid to etch Dental crowns. And we need to do it intraorally. As long as there is no splatter and proper protection is used and careful removal…its not that scary
