Air Dry Clay – Grace Clay : Another Discovery

I’m always discovering something new about air dry clay, in this case, Grace Clay. I bought some grace clay recently, and when it arrived, I pressed on the package to get a sense of whether it’s a fresh pack of clay or not. When it didn’t feel as soft as another batch of clay that I’ve got, I started investigating.
I studied the packaging and pressed on both packets of Grace Clay again (bought at different times). I suddenly thought of how my mom taught me how to tell if a fish is fresh when buying one in the market. One of the ways to tell was by pressing the meat with your finger. It should be resilient enough so your indentation disappears. If your fingerprint remains, move on.
Now, simply reverse this theory for testing Grace Clay. If the indentation remains, or it takes a longer time for the clay to revert back to its original shape, then it is a fresh packet. If it feels hard, move on.
I flipped to the back of the packaging and started to look for signs. Noticing a difference, I seriously wonder if this was the cause of it. I also did a search on the internet to find images of Grace Clay. I specifically wanted to see the back packaging (Not the front). But all I found are images of the front packaging which wasn’t helpful in my research.
Are there even “grades” for Grace Clay? But the packaging seems to indicate so. Even a non-clay user whom I asked thinks that it refers to Grade A and Grade B from the print. What do you think?
I did the finger indentation test just to show you what I meant. Below are the results.
This means details being sculpted on the Grade B clay would show up less obvious than on Grade A clay since it would spring back slightly, compared to Grade A which is softer and likely to hold details better.
I then tested the Grade B Grace Clay texture. I was thinking that maybe the finger indentation test was just psychological on my part. Maybe there would be no difference. I can recall very clearly how Grade A Grace Clay felt like on my fingers. It was very moist and soft. I can definitely say there is some difference. It’s not as soft as Grade A. Grade A also tend to retain its softness very well even after you’ve opened the packaging and keep it in good condition as what I’ve described in my tips here.
Does it mean it’s Doom’s Day?
This might be what you’re most concerned about. What does it mean to you as a user? Unfortunately, there really isn’t a good or bad because everyone sculpts different things in different sizes. How fast they consume the clay, and how well they keep their clay are other factors to consider.
Sure, of course everyone wants the best Grade, considering if my suspicion is true that there really is a Grade differentiation for Grace Clay. Based on my personal experience, the Grade A Clay keeps really well even for over a year. It remains soft. But what if you didn’t know beforehand, and you already have a Grade B clay sitting in your cupboard?
I always think that there are ways to work around it. Although you can’t change the texture of the clay, but you can think of what are the things that you can use it for and how you can use that to your advantage. What about making bigger items, or items that does not need that many fine details but still in good, long lasting durable quality?
This might also be a good experimental opportunity to mix it with other clays to see what results you can achieve.
You should always also consider these questions when buying your clay.
  • What kind of things are you making them with mostly? (this should give you a rough indication of usage each time)
  • How often would you be using the clay? (Once a week, everyday, every other week, once in a blue moon?)
  • Would you be able to store it well until the next time you are using it?
So what is the Grade of your Grace Clay? Start flipping to the back of your packaging and inspect it today. I would love to hear from you, so I can continue to investigate and research. Would we even discover a Grade C or D? Or was it a batch number? Let me know. :)


  1. Phew! I got a Grade A. Thank you for the discovery.

  2. So glad to know yours is a Grade A. Thank you for taking the time to check and commenting! I am curious to know if there are other Grades besides A and B..

    Happy New Year!!

  3. ooo!!! i seldom stock on my Grace, buy as and when i need it, never noticed this either! Thanks for highlighting it! I will head back to the office and check it out too....

    i've also discovered that some packs have a production date sticker on the back, i do not know if this depends on the supplier or no? anyhow, interesting! HRM HRM i love posts like this LOL


  4. ohnoes, mine's a Grade B! i do wonder about whether the differentiation is for local/export too, i got mine direct from Japan, so i'm really wondering about it.

    However, i did a 'press the fish' (XD ) test like you did, and mine was really soft. then again this was a recent purchase (maybe 2 mths ago?) so that might have set it apart.

  5. I found this article.

    my pack is E3-GRA-C
    the E means the production year (only goes up to F)


    then the 3 after the E means the month, so its produced in 2011 March but i still couldn't find out the GRA-"C" means, but doesn't seems like its the grade

  6. Hi Grace

    Thank you for sharing more information with regards to the alphabet and corresponding years of manufacturing! Certainly very helpful! :)

  7. Mine says CA-GRA-C
    Grade C?

    I just started using Grace Clay. I left my charm to dry and as an experiment, I bend the cookie. It cracked with white lines! Does this usually happen? Does it mean that the charms made from Grace isn't good in withstanding abuse of being a handphone strap? Please advice!

    Thank you!

  8. Hi Fuyumi,

    I find it hard to make a proper diagnosis without knowing the full details of your experiment, so I cannot comment on it. But in general, Grace Clay is an extremely durable clay and it can be used to make charms. Keep experimenting and have fun! :)

  9. I got both GRA-A and GRA-C and C does feel firmer by touch. I did point out to the store owner when I saw her stock coded as C and asked if she knew. She said those were her new inventory and she still got half a box behind her cashier. She looked at the order form and there was no choices on grade. She said she would ask her purchaser, but I never found out if she did.

  10. Thank you for sharing your findings. :) Do update again if you happen to find out more from the store owner. :)


Thank you so much for leaving me a comment! I appreciate you visiting my blog, and taking the time to read and leaving me comments! I do read all of them :)
