Wooden Handles.......

07 April 2014 - 07:49 AM

...........for pots.


I making a baskety/bowly *thing* which will have a wooden handle, it's a piece of Gorse.


I've stripped off any bark and soaked it in hot water and bleach and it's now drying out.


The question is, do I treat the handle any further and what with?  Varnish, wax, something else, or just leave it natural: are there any sort of conventional procedures for wooden handles?


The glaze is likely to be pale rather than dark - not yet reached an exact decision on that one.


Pic below, the finished handle will be about an inch shorter at each end.

Spray Gun Question.

23 December 2013 - 01:46 PM

I have a small compressor - 1.25 hp, the output is 5cfm, I'd like to use this for spraying glaze but am struggling to decide on a gun.


In an ideal world I'd have a larger compressor but that's not going to happen yet.


I've found spray guns with a 1.8mm nozzle which requires 4.3cfm and another with a 1.5mm nozzle which requires 4.2 - 7.0 cfm and several with smaller nozzles at either 1.0mm or 0.8mm, one in particular of those last two only requires 1.6- 4.0 cfm.


Of the spray guns I've found, some are HVLP and some are LVLP, is one better than the other for glazing, and why?


I'm looking for the larger nozzles (1.5mm & 1.8mm)  because all that I've found on the net with regard to spraying glazes says that that's what's needed. 


I'm puzzled however as to why I would need that size nozzle.  If my glaze has been through a 100mesh sieve with a hole size of 0.152mm  why do I need such a large nozzle?


Next question, I've used the spray equipment at college and I know that I don't spray anything for more than a few seconds at a time, does this mean that I can use a gun with greater requirements than the compressor is capable of delivering if the gun was used constantly?


There is no Harbour Freight in the UK, so please don't send me there - but should I just buy the cheapest that seems closest to my requirements and give it a try?   It may be quicker in the long run, any detailed info on this is so hard to find.

What Are They Called?

15 December 2013 - 05:21 PM

Plugs, bungs stoppers, the sort of thing to fill the filling holes in salt cellars etc..


I have it in my head that for ceramic purposes there is a collective name for these items, (which would be very useful for searching ceramic suppliers websites). :)


The name I can't get out of my head  is *Natches* but these seem to be for moulds.



Lighten A Glaze?

22 October 2013 - 02:25 PM

I mixed a glaze; I quite like it as it is for some things, but in general terms it's definitely a little darker than I would like when it's been fired.


Is there a tried and trusted method to make it lighter?


Options I've considered so far (in order of what I expect to be the most effective) include mixing a further batch of the base with no colourants and adding that to the original mix or just adding some Tin Oxide or some Titanium Dioxide.


 If it helps, the colourants involved are RIO @1% and Iron Oxide Yellow  (so, more RIO  :rolleyes: )  @3% .


Any suggestions?

Kiln Loading Question

11 October 2013 - 04:18 PM

I loaded my kiln today for a glaze fire (it's a small top loading electric kiln - (18" dia X 18 " high int.), I hadn't really realised before I started loading but everything I was firing was very shallow, no tall stuff at all,  I ran out of shelves (4) before I ran out of room in the kiln.



Usually i'm fiddling and faffing to get it all in and it looked a bit strange with 6 or 7 inches of spare space above the last pieces, so, I removed the top two shelves and used longer posts just to give everything more room (in height terms anyway).


Was I wasting my time?  Will it make any noticeable difference to anything?
