Nice one! Yes, Osmo oil I used can Sand between coats, but literally like wiping with the paper not sanding. Then second coat. Sanded with 240g
No, No and Thrice No!! Horrible things! Nothing designed better to blunt the edge of nice sharp cooking knives than glass chopping boards!. My beautiful sharp japanese cleaver will virtually cut a ripe tomato just by resting on it. If I ever caught someone using it on a glass chopping board............... BTW - Ace job!
