I am currently designing & engraving a range of pot trivets to trial at market
I have purchased Spice Kitchen Hot Pot Stand in round and square. The round ones feel different in texture & firmness. They have a burnt appearance where they have been engraved and feel like they need to be sealed post engraving. I have found for best results only use square trivets if using this brand they have a softer finish and love to be engraved
