No.
It is a bad idea. You will ruin your fireplace, and when the dry little needles/leaves catch fire they will spread everywhere. Learned this the hard way.
No, it is not safe to burn wood in a gas fireplace with a chimney designed for gas.
no
Check with Martin for an owner's manual. Unless a fireplace is specifically rated as multi-fuel, a gas fireplace cannot safely burn wood.
No, it is not safe to burn. It is toxic.
yes you can burn cactuse
You really should not burn ANY solid fuel in a gas fireplace.
You can burn your dishes, but only if they are paper (or cardboard) dishes. Ceramic dishes do not burn. Plastic dishes do burn, but will produce a noxious smoke. And if you do want to burn your dishes, burn them only in a properly constructed fireplace or fire pit, so that the fire remains controlled, and does not spread. Fire can be amazingly dangerous.
I do.
Yes.
1. Treated lumber- the chemicals used to prevent rot and insects make for dangerous smoke. 2. Redwood- wood contains natually occurring toxic chemicals 3. Pine and fir- generate high amounts of creosote, hazard of chimney fires (can be used, but with care and cleaning the flue) Low heat values.
