Posted 27 Feb 2013A side issue to glaze disposal that I have been wondering about: What do you do with the water that you use to wash out the brushes and pouring utensils when you glaze? ( I use commercial glaze and brush on almost all of my glazes.) There is quite a bit of sediment in the bottom of the bucket. I have been dumping the water in the far corner of my back yard but now have a new puppy that likes to eat grass and am a little concerned dumping the water with the sediment in the bottom.
Settle out all the sediments til the water layer is clear, dry them out, and then they are needing to be disposed of as "unknown content" potentially toxic wastes. If you are a private hobby potter...... use a household hazardous waste day. If you are a business...... you have potential other issues. But likely you are what is known as a a "small generator"...and below the regulatory threshold for needing a toxic waste handler.
It actually is a bit of a conundrum for the folks that are "in between". How to get right of the stuff. You CAN contract with a waste handler. But it is expensive. But you typically CAN'T use the "household" days (legally).
Make a THICK bisque fired stoneware bowl "crucible". Put the dried out old sediments into it. Fire it to a temperature that the mass sinters into a hard fused lump.... but does not metly into a glass. Throw it in the landfill.....it is pretty stable. FOr a cone 9-10 stoneware firing operation........ firing this to about cone 4-6 is usually adequate.
If you are not using soluble materials in your glazes .... the clear water content should not be an issue to opour on the grass. Get the MSDSs for the commercial glazes to figure out what THEY are using in the mixes.
Thanks for the information. I don't generate much waste so I think your suggestion to fire the sediments is probably best for me. At the community studio where I took classes, we just washed everything down the drain since they had a trap. Don't know what they did with the solids.

Posted 7 Feb 2013Hi
Just cruising around in the web and found this site. Thought it was interesting http://www.veniceclayartists.com
Thanks for sharing. I checked it out last night and couldn't pry myself away for two hours.
Posted 3 Feb 2013Hi All,
Long time lurker, first time poster. I'm just starting to experiment with underglazes and have a question. I keep seeing articles that talk about applying them to leather hard, bone dry or bisqued clay. Would you ever want to apply them to wet clay or would that cause the pot to colloapse?
I just had week with my four year old granddaughter and we used Amaco Velvet underglazes on cone six white clay. The bowls with the snakes and the turtle were painted bone dry the once fired with clear Amaco glaze. The other two bowls were painted on bisque fired bowls, glazed with clear on the inside and Potter's choice on the outside. All were fired together to cone 6. Colors come out darker that you would think, so we mixed some white with the dark green to make it lighter.
Hope this helps,
Posted 28 Jan 2013My goodness that Ancient Jasper is beautiful. One thing I learned about glazing ware using the Potter's Choice glazes is not to talk to anyone, it is too easy to lose count of the coats when applying the glaze; especially when brushing it on.
You're right, it's easy to get over enthusiastic in trying to get the desired result. I have never had a problem before but this time I really wanted the variation in color to be great so I went a little heavy. You can just see the glaze run under the handle of one of the mugs. Still amazed at how it ate through the shelf!
