Thanks for the info folks!


In Topic: Planning An Outdoor Stepping Stone Feature

I'd recommend adhering your tiles with commercial 'thinset' to concrete stepping stones purchased from a building supply store.   I've used 15" x 3" round concrete stepping stones and then made mosaic tiles to be added to the top.  My handmade tile pieces are about 3/8" thick. Easy to dry and fire; and when coupled with the concrete base, they're very strong. Not sure how well it would work if you were trying to adhere one large tile.  Using a mosaic approach allows you to adhere the smaller tiles, making sure there are no voids. Then grout around the mosaic.  Using the mosaic approach might reduce the potential for one very large ceramic tile to crack.   My stepping stones have been outside for 2 winters in -5F degree temps with no problems.  

 

Perhaps make 2 of them, install and see how they do over the course of a year.  Adjust your technique if needed and then do the rest.  

 

Good luck!  Nairda   


In Topic: Does Anyone Pre-Weigh Dry Ingredients For Base Glaze?

31 March 2015 - 09:34 PM

When I'm weighing out one glaze, I usually weigh out 2 others at the same time.  I check to see what glazes I'm getting low on.

 

I use 2-gallon, heavy duty zip-lock bags (Walmart) and label them with the glaze name, # of grams and the date weighed.  I take my time, double-checking each material/weight as I go, so as to not dump the wrong thing in the wrong bag.  Usually 3000 grams is the most I mix up at a time and that amount in dry weight fits the bag well.  

 

It's easy to roll the bag around and mix the dry ingredients without creating any dust.  Then, when I'm getting low on a glaze, it's ready and waiting to be mixed. I've done this for years and it works great for me.

Thanks. I went ahead and put about a tablespoon of it in a very small bisqued bowl in my kiln last night to test the outcome.


In Topic: Slab Roller Recommendations

25 March 2015 - 10:21 PM

The Bailey tabletop model is extremely heavy (70+ lbs in one piece) so it's not easy to move out of the way if you have a small work space.  The similar size North Star tabletop model is a little more expensive, but extremely portable (50 lbs) and it comes apart in 3 sections that easily fit on a small rolling dolly under a table when not in use. And the North Star allows for slabs of infinitely variable thickness unlike a shim-board style roller.
