There is a lot of debate over whether shellac is flammable or not. Some people say that it is extremely flammable, while others claim that it is not flammable at all. So, what is the truth? Is shellac flammable or not? In this blog post, we will explore the topic of shellac and fire safety and find out once and for all if this popular finish is flammable or not.
What Is Shellac And What Are Its Properties?
Shellac is a resin secreted by the female lac bug which is native to Asia. It is usually harvested from trees in India, and Thailand. The resin is then processed and sold in flakes, which are dissolved in alcohol to create shellac.
Shellac has many properties that make it an ideal wood finish. It dries quickly, it is very hard and durable, it has a high gloss, it is water resistant, and it can be buffed to a high sheen. Shellac is also flammable.
Shellac is applied as a liquid and dries into a hard film. It is available in many colors, but clear shellac is the most popular. Shellac can be applied with a brush, a rag, or a spray gun.
Is Shellac Flammable Or Not?
Yes, Shellac is flammable. Shellac is made from a resin that is secreted by the female lac bug. This resin is flammable. When shellac dries, it creates a hard film that is also flammable.
While shellac is flammable, it is not as flammable as other finishes such as varnish or polyurethane. Shellac will ignite and burn, but it does not produce a lot of heat or flames.
Shellac is often used in woodworking because it dries quickly, has a high gloss, and is durable. It is also used in many other applications such as electronics and food packaging.
Are There Any Other Risks Associated With Using Shellac In Your Home Besides Fire Risk?
There are a few other risks to be aware of when using shellac in your home.
First, shellac wood finishes are a very poisonous substance. If ingested, it can cause serious health problems.
Second, shellac is also a skin irritant. If you come in contact with it, you may experience a burning sensation or an allergic reaction.
Finally, shellac is flammable and should be used with caution around open flames.
If you decide to use shellac in your home, be sure to take the necessary precautions to avoid any accidents. Follow the manufacturer’s instructions carefully and always wear gloves and a respirator when working with this product.
Can You Use Another Finish Instead Of Shellac To Achieve The Same Finish?
Yes, other finishes can be used to achieve a similar look. Polyurethane is one option. It is a durable finish that comes in both water-based and oil-based formulas. It is available in glossy and satin finishes. You can also use lacquer, which is another flammable finish. But, it dries much faster than shellac and can be buffed to a high gloss.
No matter what finish you choose, always take the necessary precautions to avoid any accidents. Follow the manufacturer’s instructions carefully and always wear gloves and a respirator when working with flammable finishes.
Same Look And Feel Without The Risk Of A Fire Occurring?
If you are looking for a wood finish that has the same look and feel as shellac, but without the risk of fire, consider using a water-based polyurethane. Water-based polyurethanes are just as durable as shellac finishes and come in a variety of sheens. Plus, they are much safer to use since they are not flammable.

Can Shellac Spontaneously Combust?
No, shellac cannot spontaneously combust. However, it is flammable and should be kept away from open flames or other heat sources. If you are using shellac in your home, make sure to take precautions to prevent fires.
Shellac is a type of resin that is secreted by the female lac bug. It has been used for centuries as a coating and sealant. Shellac is made up of two parts, dry flakes, and alcohol. The alcohol is what makes shellac flammable.
Does Shellac Melt With Heat?
Yes, shellac can melt with heat. If it is exposed to high temperatures, shellac will start to liquefy. Once it cools, it will solidify again.
Is Shellac Flammable After Drying?
Even though it’s derived from a natural resin, once shellac is dry, it’s as flammable as any other wood finish. The evaporation of the alcohol during the drying process leaves behind a highly flammable resin. So, if you’re working with shellac, be sure to take proper safety precautions. Keep a fire extinguisher handy and never smoke while working with shellac.
When applying shellac, you need to be extra careful as even the vapors produced by the drying and evaporating shellac are flammable. If you’re working in an enclosed space, be sure to ventilate the area well. And always make sure that any rags or other materials soaked in shellac are properly disposed of.
So, is shellac flammable? Yes, it is. But with proper safety precautions, you can safely use this finish in your woodworking projects.
What Temp Does Shellac Melt?
Shellac melts at a relatively low temperature of 75°C (167°F).
Shellac can be used safely around candles and fireplaces as long as you take precautions to keep the flame away from the shellac. If you are using shellac near an open flame, make sure to keep the area well-ventilated to avoid fumes.
As with any flammable material, it is always best to err on the side of caution and use shellac in well-ventilated areas. If you are unsure about whether an area is safe to use shellac in, contact a professional for advice.
