    I’ve had the green one for 5 years and I throw some water on it and grind the bottom off and it’s soft as a babies bottom! I grind the bottom of every single pot and that is one of the things I tell all of my customers. It won’t scratch your countertops or your table tops and it is the best tool I have in my studio! Sometimes I even grind off drips and it is amazing! I’ve had it for 5+ years and I love it.

    For quite a long time I've watched my peers use this Diamond Grinding Disc. I have a body of work that uses terra sigs, so I wasn't keen on using this product in the past because I didn't want to disrupt the sigged surface. Since I've been working in porcelain and stoneware along with my terra sigged body of work I've been using a Diamond Grinding Disc from Diamond Core Tools and it is incredible! So easy to use, makes the feet of my pieces extra smooth, grinds off alumina hydrate crud (I apply dry alumina hydrate to my kiln shelves rather than kiln wash, but this product would be fantastic for those pesky lil kiln shelf buggers that stick to the feet of pots as well), and it is honestly pretty damn fun to use. Thank you Diamond Core Tools!

    Wow. So I was slightly concerned how my earthenware wild clay would handle being ground with this, you know- all the bad scenarios ran through my head- but there was a wobble that needed fixing! 60 grit performed INCREDIBLY! It took all of 2 minutes no lie. I sat dumbfounded thinking of all the time I’ve wasted in the past…. NO MORE!

    Perfect for Leveling

    I use these bats to pull off any wobble on the bottom of my pots. Levels them in 10-15 seconds. Essential studio tool.
