In Topic: Qotw: Would You Fire Your (Smaller) Work In A Trash Bin Kiln?

My post of end of last week is gone. Boo. That shouldn't happen just by switching servers :angry:

 

Evelyne (and everyone),

 

So here is how that happens.  When the servers change it takes some TIME for the rest of the "net" to get the messages about that change.  So (just making an example) maybe in Ohio and the Midwest.... the other parts of the net THERE know within a few minutes. But on the West coast..... well maybe it takes a day.  And in Poland... it takes 2 days.  And on the East coast it takes 3 days.

 

So it YOU happen to be looking at or posting something to the forums, and you are in a place that has not yet updated the server location information.... your post goes to the OLD server location information and shows up in the OLD forums.  When you look... you see it right there because you are looking at the OLD forums... not the new ones.  Anyone else that happens to be in a place that the info is not updated is also seeing your post in the old forum.  BUT the folks that are in a place that has the NEW forum location info....are looking at the NEW forum.....and they never even see your posting.  Because they can not see the old forum stuff anymore.

 

Then when YOUR part of the world catches up, you no longer see the posts that you thought were there all along.

 

At least that is my understanding of about how this stuff happens.

In Topic: The Better Mouse Trap

Yesterday, 10:27 AM

The BC causes internal hemorrhaging and bleeding.... that is what kills the mice/rats.  You'd have to get them to eat enough of it. The blood loss makes them thirsty.... which is the theory that they will go outside to find water and die there... instead of in the walls of your house.

 

The LD50 (the amount that kills 50% of the test subjects) for rats and mice is about 500 milligrams per kilogram of weight. (0.500 grams)  The average mouse weighs about 50 grams....or .05 kilos.  So they need to eat only a tiny amount........ a little over 2 and a half/100's of a gram. 

 

You'd have to mix it with something they like to eat and hope the BC doesn't add a flavor they don't like enough to avoid it. 

 

Personally...... I'd just got by a trap or some RidEx. ;)   Easier.

 

BTW... assuming the same LD50 is valid for humans...... for an LD50 dose to a human of about 175 pounds...... or 79.5 kilos....... you'd have to ingest about 40 grams of barium carbonate to have a 50% chance of living thru it to tell the tale.

In Topic: Painting On Sinks Found At The Big Box Stores.

04 July 2015 - 01:06 PM

Hi and welcome to the forums.

 

Years ago (longer than I'll admit ;) ) I was a technical glaze consultant for Sherle Waqner International and was doing some glaze development work and research for their lines of sinks, toilets, and bathtubs.  As I remember...... true porcelain,..... the base glaze (back then) were fired to cone 9-10.  Then overglaze enamels and lusters were fired onto those background glazes. 

 

But they make really "high end" stuff.  I think that it will depend on the particular sink and market segment they are targeting. 

 

You might check to see what the individual manufacturer's (Kohler, etc.) sites might give for any clues.

In Topic: Cerdec Degussa Intense Red Acting As A Flux

04 July 2015 - 11:41 AM

Any "wash" put under an applied glaze layer has the potential to have the glaze layer above it not adhere to the bisque.  It is like deliberately adding "dust".

 

SO was it fluxing... or did it just cause the glaze to peel away and then overly thinck... ran.  And some just fell right off and melted on the shelf?

 

best,
