Thanks for the tip on checking each glaze. If you order online there is no way to do that unless you ask the seller to do it before purchase. I only have 2 Sahara glazes: the Oatmeal & Textured Tan. I like the oatmeal but will probably add some yellow stain to it & see what happens. It IS a pretty matt glaze & will cover very dark clay. I don't care for the Tan at all. They both say "greenware", so you could be right. The only time I've seen glaze used on greenware was when I was…

They both say "greenware", so you could be right. The only time I've seen glaze used on greenware was when I was doing some firing for a pottery studio & some people were putting Duncan Concepts on their pieces. You might look into that - also Mayco Stroke & Coat which comes in bright colors & some (it says on the bottle) are very stable at ^5. Go on Mayco's website & find their high fire PDF. They list all their glazes & what happens to them fired at ^5. VERY HELPFUL!

<p>I agree with being hesitant to use on greenware. It just seemed weird for sure. I am experimenting with a construction method that uses slip and gauze. Being able to skip the bisque firing lets me avoid the very fragile stage between the bisque and glaze firing so for me it is very useful. My last piece consisted of bisque fired clay AND greenware and it even worked on that. It is pretty much experimental construction.<br></br> <br></br> <cite>Marti Howell said:…</cite></p>

<p>Most Amaco glazes are pudding thick to keep the ingredients fully suspended, so they likely contain added bentonite. As a result one layer of glaze can look pretty thick, yet virtually all Amaco glazes turn out best with three layers. It helps to thin the first coat to assure full application, or smooth the pudding thick glaze over the bisque with your finger.</p>

<p></p>
<p>Very few have a tendency to run, other than the fickle PC-4 Palladium, and to a lesser extent PC-2 Saturation Gold which seems to have been reformulated to flow less than it did four years ago So three coats doesn't relate to glazes running in the kiln, unless you fire to Cone 7 and hotter where most of the Cone 5/6 glazes become very fluid.</p>
<p></p>
<p>Tin Oxide really adds a lot of shine and appeal to any glaze, creating variegation when used with iron oxide and color changes in other oxides, even when it is applied under another glaze. </p>
<p>Why mention tin? PC-32 Albany Slip is most similar to tin, iron, strontium glazes like Cream Breaking Rust with 13% tin oxide, which we make for an ingredient cost of $1.83 per dry pound. I'd guess a pint of Amaco contains one pound of dry glaze - so our pint costs about 90% less than what Amaco charges. So there's a big incentive to make glazes.</p>
<p></p>
<p>Others iron-tin glazes are Creamy Rust, or the orange Bailey Shino, both with less tin oxide. I think all of these glazes are far more attractive than the original Albany Slip with lithium carbonate and tin oxide, which produces a plain-jane brown without much variation.</p>
<p></p>
<p>Rather than order a <strong>Rutile Wash</strong>, I'd just purchase rutile. I'll know tomorrow how the Dark Rutile from US Pigment looks in "Honey ^6" and post a photo. For us Light Ceramic Rutile from Laguna Clay is a dud, like adding ordinary titanium dioxide, creating a whitened matte glaze without the rutile streamers.</p>
<p></p>
<p>Mayco has an interesting selection of Cone 06 glazes which contain Rabco Specs. <a rel="nofollow" href="http://www.rabcospecks.com/" target="_blank">http://www.rabcospecks.com/</a></p>
<p></p>
<p>For us, an all-in-one Medium-Slow firing of greenware to Cone 6 is more costly than firing Medium-Slow to bisque, applying the glaze and firing again to Cone 6 at Medium-Fast.</p>
<p>We do often fire Cone 06 glazes along with Cone 04 bisque to a compromise Cone 05, but this the carbon burning-off poisons Cadmium-Selenium red glazes - and those with glazed pieces in the bisque firing are not happy if any of the greenware pops-off some clay bits.</p>

I don't fire on greenware, but their are pics on the Amaco website that say "once fired". They are PC glazes. I think the potter is named Josh. They have a lot of info on there, but I've never seen where it said to use any of their glazes on greenware. Does it say that on the jar?

<p>thanks for all the information. I am stuck at this point with only using the glazes that can be applied to greenware. The PC glazes need to be applied to bisque ware only? Or do you use it on greenware too?</p>
<p></p>
<p>I am just going to have to do some test tiles, no getting around it! I'll try to get photos of different combinations and share them with you.</p>
<p>thanks again</p>
