  1. Over th'wheel, that's a great idea! I'm looking at repurposing a small workbench to a wheeled cart (a set of 2" casters on Amaz-ing is ~sixteen bucks) - will it fit over my wheel? hmmm

    Bubbles in Glaze

    "Take your liner glaze over top and down" Tony Hansen has a vid on clean glaze boundary, "Liner Glazing a Stoneware Mug" https://www.youtube.com/watch?v=QlZqlsF1rFU To get the liner wrapped further down, and get the clean/sharp transition, a feature that the knife can run against helps. ...also helps to not be in no hurry, as takes a while for moisture absorbed by th' clay from the liner glaze to dry, also takes a good while for the wax to really set up and cut well without peeling.
  3. "Higher electric rates will Reduce your cash flow, and lower electric will oxidize your profits." I'm guessin' rates are on the high end here in CA; that said, we're on "time of use" - "peak" is almost 50 cents/kwh, and "off peak" is about 16 cents/kwh ("partial peak" is in between somwhar). We have a solar array, hence just about always produce more than we use during "peak" hours. Key to firin' the electric kiln is to go on weekends; in winter, all weekend is off peak; in summer, there's a partial peak window 5 to 8 p.m.; if'n I get up early enough, that partial peak can be avoided. Short version: check t'see if there are rate deals available in your area. Note: we're also on tiered usage - if we go over "baseline" kwh for the month, all three rates go up; there are more tiers after that...
  4. If your piece will be bisque fired before glaze fire, perhaps you can have some lil' test tiles bisqued at same time as your piece? From there, try several glaze options on the test tiles (hence, your piece skips one glaze cycle). The test tiles can be simple, try capturing the essence - just one or two "steps" of about the same thickness and add a base to capture any runoff. Just this much would give you an'idea Can you identify the clay? What brand, which one? What's it fired to (temp or cone)? I read "patience" as having to do with creating the tests - on re-read, it has to do with firing schedule, yes? My bad.

    Glaze Chemisty Education

    Local JC doesn't offer glaze chem; there are seven to ten mid fire glazes to use, period. However, instructor got me recipes for most of them (the red, particularly). They do have an Independent Study class option; perhaps later on I'll go back for that and focus on glazes (for "my" clays). My initial journey into glazes was eased by Peterson's book, The Art and Craft of Clay - her explanation of unity makes sense to me! ...there's also a rundown of ingredients in there. Good place to start, imo, and refer back to... Tony Hansen's website and vids, a treasure-trove. Steve Loucks "Easy way to adjust glazes" vid John Britt's book and vids Hasselberth's Frog Pond Pottery website - he has some recipes with commentary on thar. I hope to get hands on his book at some point... This forum, another treasure-trove! There is so much to know! I'd chosen seven recipes, then acquired ingredients to make them; ahead is test, trial, adjust; I can't go back and undo the initial choices - looks like (so far), there were a few good ones (aren't I lucky?).
  6. This one? Looks like good ol' smooth clay. 1925F, yah, that's hot! Looks like glass slump is 600-700 cooler'n'that (which Hitch said a'ready). Make some stuff!

    Studio Design

    me 2.5 cents Insulation under slab well worth considering, depending on location (Ohio?) and floor's depth below grade... ihmo, mopping/hosing concrete is easier when the concrete is sealed - check out the gas station islands; some of them may be slippery when wet, however, there are ways to correct that. For hvac, given the building is well insulated, I love the mini-split heat pumps these days - target your spaces, an' no loss through ductwork.
  9. "...make my budget look like a pittance." Aye that! Looking over what I have into bikes (the pedal kind) - I only have five, two of which get ridden regularly - waay more $ than clay! Add in clothing, tools, accessories, ongoing repair and replacements. Friends an' fam into motorcycles, music, sewing, off-roading, attending pro sports, participating in sanctioned sport (add th' travelling)... whooha, they spend lots o'cash. Beats bein' bored, carry on.
  10. Good question (mebbe some tips on $aving and choosing will get recorded)! Set of tools for local JC class, class fees, ~$265. Used (barely, and over three years transferable warrantee remaining) Hill wheel was ~$900, included fifty lbs clay, two bats, an' some tools. Fifty pounds clay, another bat, ~$50; shipping clay not cheap! ...resolve to make next clay purchase in Hulk bulk. Used kiln from nice lady, $500, included new shelf kit, the old warped scabby shelves, some oxides, cones, and furniture (hi Ann!). Side trip to Aardvark* whilst in LA, ~1200 lbs of clay, glaze materials, other stuff ...pyrometer, plaster, a few tools, ~$780. Another class at the local JC, ~$255; while carting self and tools back and forth isn't ideal, having pieces fired every week is nice - shortens the loop, eh? Mainly, I like(d) meeting people, getting to know them, and seeing everyone's work each week. Call it 3000 bucks then, as there were a few tools, bag o' clay, gas an' such for pick up trips, some screws an' whatnot for shelves in the studio. Oops, forgot materials for vents, and (#%_ electrician and materials for kiln electric, add six hunn'd bucks, call it $3700 then. Egad, what have me done? Getting organized in progress right now (in a minute...) - mostly scraps and shelves from previous homes**. I like the metal tracks; they hold a lot and can be moved up an' down; bought a few more at Home Debit yesterday. Caught the clay bug in local JC class, almost a year ago; at that time, was still working, and planned to keep working for a few more years. Well, circumstances changed, gave notice late May, bye-bye. Ahem, had been mulling over "next" for quite a few years now - several activities had made the list, including woodworking, furniture refinishing, handyman business... Turns out I like the clay. I'm not in a hurry to get commercial - likely won't ever make it a full time roar - however, am looking to branch out into sales, to defray ongoing expenses an' get rid o' the piles o' pieces! My biz plan includes fixed percentage o' proceeds to local children's, women's, and homeless services. Well, enough about me! *Looks like Aardvark isn't back to mixing clay; wishing them all the best. **Learned the hard way that anything attached to the house (e.g. light fixtures, shelving) is included in the sale, hence, take down any bits that you want to keep before showing y'house for sale!

    Slip- Engobe Study

    A new (to me) word! "The Twaddell scale is a hydrometer scale for reporting the measured specific gravity of a liquid relative to water. On this scale, a specific gravity of 1.000 is reported as 0, and 2.000 reports as 200. … named after the scientific instrument manufacturer W. Twaddell of Glasgow, who first developed hydrometers on this scale at the start of the 19th century."

    reconstitute dip glazes

    Container lids that don' have a gasket (e.g. rubber), or metal to metal (like a paint can) will "breathe" - where every exhalation includes water - to some degree. I'm using plastic containers with snap on lids, hence checking density (specific gravity) is necessary, although storage out of the sun (and big temperature swings) helps a lot.
  13. Hi PJ! I haven't worked with a Randall, nor a Lockerbie (although I have touched - cleaned - haha, several...), let alone examine the shaft and wheel head fit up. However, as I'm curious, did find a manual https://drive.google.com/file/d/0BxdPYpF6jogjRkxmTm1UQkUtRjNUMEJzT0RhUkMwLUhLaG53/view from here http://www.pottery-on-the-wheel.com/randall-kick-wheel.html Note the shaft is described as "taper" - hence, likely that actual/genuine Randall wheel heads are the only fit, but I'm just guessing there. Should it turn out that finding same is difficult, an adapter should be easy enough to machine, given you can find a willing machinist! Looks like the connection to that .pdf is rather slow - wait for all six pages to load up...
  14. Aaah, memories! Our first home had a low crawlspace - get between joists to roll from front to back. The word "swell" reminds me - suggest long shirtsleeves and pants, both secured with rubber bands (plural), and pants tucked in socks, collar fully buttoned up, and look look look before entering. I find both black widows an' fiddlers (brown recluse) in the oddest places, e.g. in the garage/studio, right where I'd put my hand; tucked up in the garbage can hand hold; outside the front door, between knee and forehead level.
