A working link is

"What Has Worked for Me

I have only microwaved simple bowls, or tiles. The objects have all had a fairly even wall thickness, and have not had handles or other added parts."


These would all be thin objects, probably 1/4" or less. IMHO anyone contemplating zapping mud should read the whole post to see how Peter does it without flying shrapnel.

Dear Pam,  To my previous post I should add a warning that if not done properly, clay could explode in a microwave oven.  To read how an artist has actually used the microwave with clay go to the link below  http://opopots.blogspot.com/2009/06/using-microwave-to-dry-clay.html  There are plenty of comments to the blog.  Clearly microwave cannot be used to "fire" clay; it can used to "dry" clay. But that gives sufficient strength to the tiles that the blogger writes about.

papercrete/paper adobe. I have stopped using cement long ago and only use clay  for a binder in my blocks. I use cardboard for the pulp and it works very well  indeed with clay. I don't even use much clay as I have found that very little is  needed, perhaps one small shovelful per block. I too am not much on details but  rather focus on results. I also make blocks with only cardboard pulp and they  work very well and are of course lighter than the blocks made with clay. The  idea that clay does not adhere to anything  is rather ludicrous as it sticks to  everything and is a pain to remove when it dries. It also expands when subjected  to water, which is why basement and foundation walls in heavy clay soils benefit  from a layer of gravel next to the concrete.    --- On Fri, 5/20/11,  ashokchand2000 <ashokchand2000@...> wrote:

In a papercrete mixer put the newsprint and water but do not put in the cement  and run it.  What will result?  In my understanding, the mixer, working as a pulper alone, will shred the  newsprint into wood fibre and mix air in the mix making it quite light and  foamy.  If you add cement to the mix, papercrete results. So what is different in the two experiments?  Cement actually coats the shredded newsprint (wood fibre) with itself protecting  the wood fibre from the environment so that it no longer decays. Also, to some  extent,the cement expands and fills the voids created by the mixing. The long  setting time of papercrete allows the voids to gather some strength.  Clay has no natural affinity to anything. That includes wood fibre. It will not  coat individual wood fibres but will mix between the wood fibres.   It does not expand on coming in contact with  water.  This suggests that the resulting mix will have very poor strength and will decay  with time.

  How about starting out by substituting clay for cement in the same amount then  adjusting from there. Please share if you do this. I have been doing it and am  having good results, but seem to think more clay than cement is required. I am  serious about your sharing your results. Attention to detail is not my forte.
