A kiln shelf is not necessary to do glass fusing, but it is extremely helpful to have air circulating around your glass pieces. The circulating air helps to ensure that your glass is heating at an even temperature. Yes, you can fuse on the kiln bottom, but try to place your items on posts so that you achieve the needed air circulation around your piece.
