1 inch unglazed porcelain hex tiles. You can buy them in full sheets or in small quantities that will give you enough to make your tile tool.
Hex tiles are used to make a tile tool for grinding your telescope mirror. They create a channeled tool that works faster and uses abrasives more efficiently than using a regular glass tool. Channel tools are much cheaper than using a second glass blank but require a little work to make them.
