Woodturning - Just add Salt and Pepper

I've had these ceramic grinder inserts for sometime, just never got round to using them until now. Wanted to see how long these would take to see if they are worth putting on my website, these two will be on there as the trial pieces and then later on I will start offering these. Just wanted to narrow down the process of making them.

Wood is Apple covered in plenty of Burl, finished in shellac and then buffed. Resin is food safe resin.
