![]() Sunni did an experiment on using translucent liquid clay instead of glue (on eggs…would work as well for wood?)… she tried both baking the TLS beforre adding her clay (cane slices) and also adding clay over the still-wet TLS. ….for later painting or varnishing, raised grain is bad news and must be sanded smooth …but for using with clay, but I’m curious to know whether the fuzzy fibres might not mesh with the clay, thus creating a good mechanical bond? …And does the glue provide a mechanical or a chemical bond, or both, with clay ? Karen G. ….If applied while the wood was still warm from the oven, I think you’d get a near perfect moisture seal that way. JeanneĪnything water based which is applied to wood will ‘raise the grain’, making the wood a bit fuzzy as the wood fibres absorb the water… but once dry, the primer paint would really seal the wood preventing it from absorbing any moisture. …I ended up putting a layer of gesso on the wood before covering with clay. ….painting with acrylic seals the moisture in the wood (all wood contains moisture no matter how long you try to dry it). She painted the frame with acrylic paint first, no other treatment necessary before applying the clay. ![]() One more solution to take care of moisture in unfinished wood… Donna Kato decorated a frame with polyclay on HGTV recently. The only time I have incountered cracks in my clay is when the clay is uneven in thickness. ….I cover my wood with Elmers ‘wood’ glue first. …I usually bake again at this point(?), before I apply the cane slices, or whatever. …then your clay “base” layer should stick quite well to the surface. …I coat my wood eggs with Sobo glue before baking (let dry completely). even tenting or enclosed baking can moderate the temp too let the glue dry completely before adding any clay (or moisture in the glue can bubble up because it has no way to escape) …may also help to let rest at least a while before baking, and bake and cool as gradually as possible. …a layer of white-type glue (like regular Elmer’s or Sobo). Jon Anderson uses armatures under his clay coverings from scrap clay or hand carved wood…after applying slices, he bakes “for a period of hours “further reducing the images (?) and tightening the spaces (?) between the individual tiles… process may create crazing or tiny fissures in the clay”… (wood not completely dried out, or ?) … …this might also depend on the size of the wood object –or natural material like a gourd, nut shell or piece of bark– and how “dried out” it is already… it’s probably fine to dry most anything at 150-200 degrees, for a lot longer too this will help prevent the moisture present in unfinished wood from expanding during the later baking and causing bubbling or cracking in the clay covering. at 250-275 degrees (soft woods?) to dry them ou t completely. When covering unfinished or raw wood items, you must heat the wood for about 15 min. NOTE: do not do ice water plunges (to increase clarity of translucent clays) with polymer-covered wood items unless they are completely sealed first (the wood may swell and crack the clay) … may be okay though if the plunge is very brief? You need to dry it in the oven before you coat with glue. She’s not only a very nice person, but she has a great book on weekend projects called “The Weekend Crafter – Polymer Clay”. But then again, I’m really into miniatures and sculpture. ![]() As for books, my favorite authors are Sue Heaser and Maureen Carlson. You can also check out it’s one of the best polyclay sites out there. Also, make sure there aren’t smudges or oils on the wood. I’ve found that drying the wood in a 200 degree oven for about an hour then leaving it in overnight while the oven cools is a great help. If possible, try to use an accurate oven thermometer!! It really helps. ![]() They are very unreliable as far as heat regulation goes, and you are much better off baking a project that’s say, bigger than a golf ball, in a regular oven. I have one that’s probably 10 years old it works like a charm. Here’s my 2 cents worth, too! I’ve found that in my 12 years of being a polyclay frEAK that toaster ovens are often in need of an exorcism.
