  • Fire Clay

    I found powdered fire clay at a mason supply store near me and it was $65 for 50lb bags. I also found powdwred fire clay at a pottery ceramic supply store and it was $16 for 50lbs. Obviously the mason supply store is the correct fire clay no doubt, but is there a difference in the cermic pottery store fire clay? Its called Hawthorn Bond and here is the link to the cut sheet https://www.google.com/url?sa=t&sour...3vEnGSDGv8ZXhs It talks about mesh which I assume is the finess of the powder? I obviously would rather get it cheaper as long as it works correctly for me.

    The ceramics store clay will be fine. It’s shrinkage rate is not excessive. Actually any powdered clay should be suitable for the temperatures we fire to except Bentonite which has extremely small particle size resulting in too much shrinkage.

          No, it should not. From the link, I can't find where it says that it contains "portland"? I see in the product overview that it "can be blended with portland to make masonry cement". Which is true.

            The link that you provided is for Type S Hydrated lime. That is what you want for the home brew. However, after going back to the first part of your post
            but it says in the package it contains portland
            Is it possible that you were looking at a bag of Type S Masonry Cement while in the store?

                  I stand corrected. The labeling by Quikrete is misleading. Type S Hydrated lime should have no portland in it. So, I'm guessing that it is a portland/lme masonry cement. To be Type S Masonry Cement, the mix will be 1 part lime and 2 parts portland cement and should be labeled as a cement imo.

                      Ring the manufacturer to find out the proportion of the two materials.

                          Quickrete answered both my questions through the home depot website. They told me there is no portland in the product and then i asked why does the bag say it does. Quickrete's response was the graphic on Home Depot's website is inaccurate and the hydrated lime contains no portland. So I guess that solved that question. Here is the link to the questions I asked and the manufacturer's response.

                            Great catch on reading the labeling for the graphic. You also did a great job doing the leg work with Quikrete to clear this up. As of my post, the misleading graphic is still up on Homer's website.

                              Thanks! Im sure that graphic will be up for a long time lol...kind of funny the description on home depot says hydrated lime cement when you read the description...im going to go see it in person and see whats actually there. Im an electrician but have done many different things but buying raw masonry materials instead of buying a pre mix is not something i would normally do so im reading the crap out of these labels and descriptions because I dont want to buy the wrong stuff and finding out too late. Im so greatful this forum is here it really helps to have everyone chime in with their knowledge and experiences. I hope I can contribute something to this community as others have.
