    hantremmer got a reaction from nancylee in Beginning wheel throwing projects   
    I'm practicing cylinders again.  Can someone give me a height to aim for when throwing with 1kg / 2.2lb of clay?  I need something to aim for, even if it's difficult.  I'll set a gauge up so I can keep trying to hit that height.
    Incidentally, here in the UK we call this # a hash sign.  I still find it confusing when people refer to it as a pound sign, which is one of these: £.

    hantremmer got a reaction from LeeU in 6,000 year old pots were used as babies' bottles   
    A study of tiny clay pots with small spouts discovered at archaeological digs reveals that the vessels were likely used as milk bottles to feed babies. The specialized pots have long been found at sites around the world, and scientists have speculated that they may have been used to feed children or the sick. By looking at the lingering traces of ancient food inside these clay bottles, scientists have finally unlocked their secrets.

    Drilling a wheel head isn't too difficult. Most of them are aluminum, so they drill easily. The holes should be 1/4", and 10" apart on center. Bat pins are 1/4-20 socket cap screws. You can center up a good bat and mark the holes as a starting point for your measurements. Use a punch first, then drill with a small bit, like 1/8" to start, and work up to the 1/4". Go slowly, and keep checking your drill from two sides to keep it fairly plumb. If it's not 100% plumb it's not a deal breaker. If you mess up, you can always drill a new set of holes a couple inches away from the bad ones. Extra holes in the head won't hurt anything, or you can fill them with JB Weld exoxy putty.

    Thanks for all the replies.  I manged to get it off.  
    I think the platter is 6-8mm thick and a little over 13" across (my wheelhead isn't 14" as I first thought, so my dimensions were off).
    I wired off with a curly wire.   I had to use a 3mm thick piece of cardboard as a wareboard, so I lifted the platter up a little and placed the 'board underneath.  Repeated a few times.  WHen the platter was half way on I lifted it gently by the rim and placed it.   The rim deformed a little and the platter was floppy, but not as badly as I expected.   I left the rim thick, which helped. 
    My Shimpo didn't come with holes for bat pins, but it does have marks on where to drill. So I'm thinking of drilling fresh ones or buying a already drilled wheelhead.

    Its most likely to thin at this point. You could re -wedge that clay when its still wet and throw one with a bit more clay so its thicker.

    14” is tough and any crease you put in it will likely reappear because the clay has been stretched locally so I think really tough to get off without bending it. I agree with the rewedge with some more clay and throw it on a full batt. Sorry, just my opinion.

    Keep the wire tight and press down against the wheel head as you drag it across.   I spin the wheel slowly as I do it.  I cut plenty of crooked bottoms before realizing that I was inadvertently coming up as I moved the wire.

    I have seen people throw large 14 inch or so plates with no bat, and lift them off the wheel holding only one edge with both hands lift, and it bends all over, then they lay it on a ware board and it flattens right out. Think I can do it! NO. . . dang it!
    I throw mine on bats, just threw a 24 inch ring on a bat for the wall of a long bread dish for communion set order.  assembled with a slab base and decorated with same stamps I used on the two chalices for the set.

    Invest in some pottery "Scoops".  Thin pieces of metal used to get under the bottom of soft wares, on the wheel.  If you don't have those, you can just use a piece of sheet metal, or something of the like, to achieve the same purpose. 
    Alternately, when it is set up enough, just try and scoot it off the wheel head, to the side, on to a bat or ware board.

    I might have read this here, but when my MDF bats warp I stack them one atop the other and put a heavy weight on them and leave them for a couple of days or so until they flatten out.  When they warp again, I flatten them again.

    Update -
    The ink has started to appear underneath the pot where it's unglazed, the footring is pretty much entirely blue, though in different shades and darknesses.  It doesn't seemed to have changed colour from the light blue / grey under the actual glaze.

    I bought the registar's ink.   I was told that it writes blue, but oxidises black.
    I brushed it over the crackle on my pot a few days ago.  It brushed on blue, but hasn't gone black.  The colour has shifted from blue to an egg-shell blue / slight grey.  It's not as vibrant.
    Maybe it will continue to change in the coming weeks or months, but it's not  what I hoped for.  That's OK though, because this was an experiment.  I don't have any reason to think it's an issue with the ink.
    There was also a lot of feathering in the cracks, where the ink has seeped into the clay.  Perhaps I used too much or it's some other reason.  The glaze has crackle, but that's not its selling point.

    hantremmer-
    Even if it was a pot to be bisque fired, the person who did the stamping should be informed that their choice of stamp ink contains metallic oxide(s), assuming it was stamped prior to firing the piece. If it was stamped after the firing, and the ink contains no metal oxide(s), it may burn off in another firing. Try having it re-fired. After all, what do you have to lose?
    Regards,
    Fred

    Shouldn’t have any difference if you didn’t have other effects (i.e. metals or combustibles attached or in proximity).

    You need to ask  if applied post or pre firing and what is in the ink.
    That way you can act accordingly.

    Hmmm doesn’t ink burn off (if it is the appropriate ink)?
    whether bisqueware or greenware or terra sig or slip should the ink not leave any residue?
    esp a clay studio I would imagine uses the appropriate ink. 
    I would take a picture and fire and see. I am though concerned about the terra sig you rubbed. Might leave some mark. 
    One time I used ink thinking underglaze.  The result was bad. Nothing. So disappointed.  Lesson learnt. Ask. Don’t assume!

    If the ink has iron or other metallics, it might not all burn out but leave a shadow. Very poor studio management, to let the pots be stamped that way, maybe the stamper was told not to handle the pots and, hopefully, the ink is made of non-metallics.

    I'm wary of anything to do with fur, especially in countries like China.   We don't know how the animals are kept or treated; some brushes made with 'wolf hair' are actually made using weasel hair and my assumption is they'd be kept in very small cages.
    Sputty -
    Thanks for the links. I hadn't heard of those shops. I went with three goat hair brushes in small, medium and large from Jackson's.
