A Practical Polymer Clay project I completed a while ago.... more on that in the future!
As I reported previously, in this article here about the Polyurethane peeling off of my pieces. (And yes, I used the exact kind recommended by many reputable Polymer Clay Artists). I had to sand off all the Polyurethane and opted for sanding, buffing and waxing. Well, since that article, I have just read from The Blue Bottle Tree's Ginger Davis' Article, that the Renaissance Wax that came highly recommended by one of my favourite Poly Clay Sites - Isn't as protective as I believed it was. The Blue Bottle Tree says it isn't as protective to pieces with Mica powder on the surface, it may even remove it and that there are even more expensive ways to achieve the waxed effects.
Needless to say, initially, I felt confused about who to believe and what I should do. I am not dissing all the valuable lessons from those I have learned and are learning from...not at all. I am saying that it is my fault for not researching on my own, by actually doing my own tests. Always have been lazy that way...finding a teaching and then devouring all they have to say, basically parroting them without questioning anything. Learning lessons the hard way means those lessons stay with you forever. Conflicting Messages?
After countless attempts using recommended finishes, I personally recommend that if you want to seal or offer a glossy surface to your pieces, do your research. I have found conflicting articles by artists who I have learned from. It seems that some of the same methods and products when used by me, don't always works as described. Doesn't mean they were wrong. Maybe I do things differently and made a mistake?! Possible.
Regardless, I foolishly (in the beginning), just embraced, without question advice by purchasing and using specific glazes and such and covered a tonne of beads. (You know how much work that is!)
And then weeks later (sometimes even days later), when I went to use my beads or pendants, I discovered the surface to be sticky and ruined! Can't tell you how frustrating that can be. :o( Not that any of the advice I gleaned was wrong or anything. It just means I have learned that lessons need to be learned through trial and error on my own, not just following others without question.
Yes as many of you may know, there are definitely well meaning tutorials from less experienced clayers (I assume) who give advice that ends up contradicting those Polymer Artists that have great reputations, the ones I trust far more, such as some of my favourites: the Polymer Clay Tutor, Christi Friesen, Katers Acres, and now, Blue Bottle Tree and Unruly Housewife. If I hadn't learned from these guys, then I would be making even bigger mistakes. So I strongly encourage endless hands on experience and research.... Some Final Thoughts....
After too many disappointing glazing moments, I highly suggest to do your own testing on small amounts to avoid wasting your time and money. Bummer is, I bought one litre of Polyurethane and other glazes, now I will not be using them on clay! Be sure to research the terrific articles and videos by the many great poly clay artists online, but don't just assume every word of advice will work for you....test them out yourself or you'll learn the hard way like me
As we create, we are always learning, right? Right! We learn from watching others create as well as from actually working with whatever your favourite art making material is. Or if you are me, you are wanting to learn and try out a variety of creating methods. For me these past couple of years, it has been all about learning the best ways to work with polymer clay. It was love at first sight. Working with polymer clay means I can use colour in a three dimensional way. For the first half century of my life, my favourite art making materials were two dimensional, acrylic paint, coloured pencils and such.

Treating The Surface Of Polymer Clay
One of the many lessons I have learned from the many great online polymer clay artists was that the best product to use if you want to glaze your baked clay is, water based polyurethane. So I bought a huge can and spent two days straight glazing my recent pieces.
Because I have also learned that it is far better to create my polymer clay pieces as smooth as possible. Unless you want texture. If the surface is smooth, it can be left or barely sanded, waxed and buffed or glazed and look great. However, it turned out that because my pieces were too smooth, the polyurethane on many pieces peeled. I like to test all pieces after my multiple failed attempts at using other glazes such as triple thick. Some end up sticky and gross. In fact, that has been number one pet peeve. Polyurethane, perfect, no sticky icky surface. It was when I tried to see how durable the shiny surface was with my finger nail, that I discovered the glaze cold peel like good sunburn does. Okay, I use to like peeling sunburnt asking (my own of course!). Needless to say, I was very disappointed.
Here are some pictures to document what happened....
This wasn't all that I glazed, but you get the idea... Wanting to know what I did wrong, I researched some more and discovered that polyurethane can peel because of natural oils the is on our hands, so you can use rubbing alcohol to wipe the surface clean of oils. As well lightly landing with a high grit sandpaper first helps it adhere. For me, it just became too frustrating because I didn't research as much as I should have. To Glaze Or Not To Glaze, That Is The Question!
As you may already know, you do not actually have to put a finish on polymer clay. The clay is far more durable than any finish. A coating of your choice (I a sticking with polyurethane used properly) is helpful if you have glitter or some such thing that you feel may rub off. Mica powder like Pearl Ex actually is fine if rubbed on in one layer onto unbaked clay. If you want to cover it before with a thin layer of liquid clay or after baking with a glaze, that is an option we have.
Surface Before The Polyurethane
Personally, after spending more hours sanding OFF all that peelable glazing, I concluded that sanding, waxing with Renaissance Gallery quality wax and buffing or just leaving it as is, will be my choice for surfaces of clay. UNLESS, the poly clay piece is a figurine or something that won't be worn or used like beads and cabochons.

Sanding Tips:
Because Polymer clay is so fine and can enter through air passages, it is best to sand using wet/dry sandpaper in a pan of water or because I physically can't do that, I have a tub of water next to my work space. Then I dip my sandpaper and piece in the water, lay them down on a towel and begin sanding. If the surface has roughness then starting with a number 600 should work to get the hard parts off. I have to keep dipping in the water because the polymer powder builds and clogs my paper fast.
If your pieces are as smooth as mine started out, 800 to 1000 works and I even have a 2000 grit paper to finish off with if I want.
Without waxing, I personally wouldn't be able to polish my pieces hard enough. I know of other artists who don't wax. They sand and then use a cotton denim or jean fabric to buff out the clay and it gets super shiny. My hands are not strong enough to do that, so I put a thin layer of Renaissance wax and let it dry for ten minutes and then polish with a soft cloth. I love the finish. So if I can achieve a nice buttery finish with my weak hands, anyone can! Imagine what you can do with healthy muscled hands!!

My flowers are okay with a thin layer of polyurethane. I love this piece.
