Replying to Chipping

my public enemys chip a ton so yesterday i decided to burn all the strings of p tex falling off the top sheet, because they were really bugging me(i know it doesnt effect the ski at all) and then i blew it out when it hit the topsheet. i did one by the binding and when it started to burn it got all flakey and there were these black flakes in the air. Did i burn the core or the sidewall? Will it mess up my works and functions? Im freaking out
