I would like to wood burn some designs into a nightstand but may want to add more burning down the road, after I coat it with shellac. From what I could gather, people mentioned to only burn and then seal, otherwise the burning after the shellac could cause issues, like releasing inhalants. Is that really an issue with shellac since it is “natural”?
you can use denatured alcohol as a solvent to strip the shellac later. might be a better option than trying to burn through the shellac
