## Questions & Answers

**Q: Could you use this on fabric that will not be washed? (Got a galaxy tapestry that I want to dot with invisible stars with it so it up reacts)**
A: It will work with fabric no problem.

**Q: How long will this last on archival printmaking paper?**
A: The longevity can vary over several factors so there is unfortunately no "one size fits all" type of answer for this. Beyond the application surface type we would need to know more details to give an approximate estimate. Best case scenario is usually 5-6 months at least. Would be best to send us a PM so we can get more of the data points needed to best advise for your particular use.

Thank you

**Q: we are looking for a crack identifier in a large tile wall.   we are thinking the cracks might show up better if the tiles were wiped with this?**
A: This ink works best on a porous or textured surface. It will still adhere to smooth surfaces like polished tile. Just not as well as a surface with some coarseness. Should work fine for this intended purpose, but of course recommend to test a small area first to ensure it will meet your needs. 

Thank you

**Q: What flavor is it?**
A: You may need to read the description again. This is a solvent based security ink. It is not for consumption what so ever. Doing so would be extremely dangerous and would 100% land you in a hospital. If you need further explanation on why drinking a flammable solvent would be bad for your health, please send us a private message.
