We suggest a rate of 1°F per minute to 212°F with a 1 hour hold at 212°F. Continue heating at a rate of 1°F per minute to 1000°F, then increase the rate to no more than 5°F per minute to operating temperature.
The heat up schedule should consider the physical states of silica more than alumina. Alumina has no changes at temperatures between 0°F - 2910°F. Silica (quartz) has two significant changes in physical state in this range. One around 1060°F where low quartz transforms to high quartz with a 5% increase in volume. Another around 1600°F when high quartz tranforms to low tridymite with a 12% increase in volume. This means there is the possibility of lining wall to buckle and/or spall as you heat up. We recommend every installation to have 1/4" minimum expansion gap every 4' when heating to 2000°F (fireplace installations). When operating closer to 3000°F we recommend 3/8" minimum expansion gap every 4'. Also, do not exceed 10°F per minute. Most gas fire applications have an immediate jump to 500°F or more; this should be avoided in the initial bake out by using a lower BTU heat source.
Yes, refer to "Smithfield Unbranded Medium Duty Firebrick" to find a listing of "Additional Fireplace/Wood Stove Sizes" that are available in High-Duty. If further shapes/sizes are needed please see Jet D.P. high duty for 100+ options.
Alsey firebrick conforms to all applicable building codes; including The International Code Counsil, The International Residential Building Code, and The National Fire Protection Association.
The standard color for Alsey firebrick is light buff; although there may be slight differences in color due to the natural variations of the raw materials. Alsey firebrick does not come in other colors but can be stained using Alsey Firebrick Stain and Color Enhancer.
This product has not been rated nor is it regulated by the FDA. Our firebrick are currently being utilzed in installations as a cooking surface. When constructing a floor/cooking surface, our larger firebrick have become more popular than the traditional 9" straight firebrick.
Yes. However, your firebrick will have better longevity if it is covered / protected from the elements.
No, Alsey Hi-Cast Refractory Castable is intended for casting pieces or patching large areas.
Alsey Hi-Cast 60 has a higher service temperature rating and is stronger. (See respective data sheets).
This product has not been rated nor is it regulated by the FDA. We do not recommend it.
Alsey Hi-Cast Refractory Castables can be used for domes, walls, floors for pizza ovens / bread ovens (see cooking surface note), wood stove inserts, fireplace inserts, etc.
We recommend 1/16 - 1/8"; definitely no greater than 1/4". At 1/4" you could experience shrinkage and cracking.
High humidity and cold temperatures can delay set-up beyond 5 days. In this case we suggest a torpedo heater with Visqueen hood to drive off moisture to allow mortar to set-up. The use of additives could also slow set-up or compromise set-up entirely.
No, do not use in outside installations. This mortar is water soluble and will eventually erode if exposed to rain or snow melt. Please use a hydraulically setting mortar for outdoor applications.
Yes, Alsey Smithfield Air-Set Refractory Mortar conforms to all applicable building codes; including The International Code Counsil, The International Residential Building Code, and The National Fire Protection Association.
The liquid on top of the mortar is Sodium Silcate that comes out due to normal settling and shipping of the product. This Sodium Silicate can be stirred back into the mortar immediately, can be poured off into a container to be added in after stirring, or can be poured off completely and not utilized. If you decide to pour off the excess there is still enough Sodium Silicate in the mortar to be effective. Most people pour it off and save it in order to add some back in to get the mortar to the consistency they desire.
Yes, Flue-Set is a hydraulically setting mortar that is non-water soluble.
The addition of Citric Acid or .10lb of baking soda to 100lbs of Flue-Set will retard set-up.
Start with 1/2 of the material and mix with 1/2 of the water. Add extra as needed. Do not retemper!
Mortar should be utilized at temperatures above 32°F and temperatures should not be allowed to fall below that before mortar is able to set-up.
Yes, please note that firebrick must be very clean (all soot must be removed) or Flue-Set will not stick.
Flue-Set sets up unusually quick and will begin set-up within 15 minutes of mixing. (The addition of Citric Acid or .10lb of baking soda to 100lbs of Flue-Set will retard set-up and allow more time to construct.) A soft Flue-Set joint is usually caused by retempering. Flue-Set must NOT be retempered; this ruins the mortar and it will not set-up properly. To repair a crumbling and degraded joint that has been retempered; grind or rake out joints with a screwdriver 3/4" to 1" deep and repoint with Flue-Set that has been mixed properly.
Alsey Firebrick Stain and Color Enhancer is formulated for use in vented fireplaces. For vent-free option see Inventory #2A4150 Vent Free Black.
No, Alsey Firebrick Stain and Color Enhancer is specifically formulated to coat Alsey Firebrick.
After laying up the brick, use a painters brush to individually paint each brick. For a monochromatic look for the bricks and mortar use a large sponge to apply over entire firebox.
Yes, but please note when wiping mortar joints transfer of color will occur.
Yes, Alsey stains may be mixed to create custom colors. However, do not mix any other products or additives with our stain.
One quart of Alsey Firebrick Stain and Color Enhancer is enough to accomplish 2 coats on approximately 75-100 firebrick.
Alsey Firebrick Stain and Color Enhancer is water soluble.
20 mesh dry milled plastic fire clay.
No, there is no setting agent in Alsey Dry Milled Fire Clay.
Old time masons have added portland and sand to create a mortar. This does not comply with building codes (see fireplace bulletin). Currently it is used as a loose insulating layer to set bricks in, it is used extensively in foundry and pottery work, and used in manufacturing processes for other products.
