In Topic: Glazed Mugs Safety

29 March 2017 - 04:51 PM

To expand a bit on Mark's comment...  I would say: "It depends..."

 

For the specific piece you described - if the "glaze" is peeling off, then I would have to assume that particular piece is NOT food-safe - for the simple reason that I would not want to ingest the material that's peeling.  (I would also question whether it is actually a fired glaze that's peeling off - or some sort of paint or other coating that was applied after the piece was fired.)

 

For ceramics in general, there are several factors that can affect whether a finished piece is "food safe":  Clay body composition, glaze ingredients; how it was fired, and even the current condition of the piece, all can make it "safe" or "un-safe". 

 

One would have to know at-least the first two factors I mentioned, to even guess whether a piece is safe. Even manufacturers who label their clay and glazes as "dinnerware safe" state that "Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination."


In Topic: Identify My Clay

Color looks a lot like "terra-cotta" flower pots - but that doesn't mean the clay is anywhere close to the same.

 

My guess would be a pit-fired earthen ware - but I've never worked with either pit-firing or earthen-ware, so just a guess.

 

It would probably help if you could tell us where "in the area" is. (Don't have to give an address - but if it really is locally dug, knowing what county & state would definitely help narrow it down.

Are you saying he doesn't think you should have the double sink draining into a single 2" drain ?

 

It is pretty standard for the two sides of a double sink to join together into a single drain, using a 'T' fitting under one of them.  (If you have a double sink in your kitchen, look under it - you'll most likely see something like this (It will look a little different if you have a disposer, but is functionally the same.):

A double laundry sink would usually be configured the same.  Installing a clay trap on one side, before it feeds into the "T" would be no different than having a disposer on one side of your kitchen sink.

 

 


In Topic: Here Is How To Get Wax Resist Out Of A Brush

Makes sense.  I've used boiling water to get candle wax out of glass candle holders - but I would think the metal part of a brush would cause problems in a microwave.  I'm thinking boil the water first - then put the brush in it - would be a safer method.

.... mostly I just want to have my utility sink and the washing machine inside, and the only place to put them is next to each other over where the laundry fixtures were when they built the house. 

 

Do you have room for a double laundry sink ?  If so, you can probably configure the drains so that only one side goes through the clay trap (similar to a disposer under a double kitchen sink).  Then, you do all of your clay cleanup on one side - and everything else, including the washing machine, on the other side.
