An Update on
It has come to my attention from several regular users of Calco Mix that there has been high level of stones and pieces of concrete etc. found in Calco. One lady told me that an exploding stone had broken the glass of her stove - that can cost a fair bit to replace depending on the type of stove..
I myself have found a collection of extraneous bits and pieces in my Calco-Mix of late. Some are harmless bits of wood etc. - others are less benign. Either the agents or those making the mix are quite careless, or could it ever be possible that this EXTRA material is being added intentionally for some reason unknown??
Above is a photo I have just taken showing a collection of rocks and concrete I found in my Calco. The lignite briquette and the 1 Euro coin are there just to show scale. The two brownish stones are that colour because they came out of the fire. Luckily I had discovered the rest before placing them in the fire. That collection represents the use of perhaps 2 to 3 bags of Calco - that is a fair bit of extraneous matter. Apart from devaluing the Calco, there is always the dangers presented by an exploding stone in the fire.
I will reserve final judgement but suffice it to say I have lost some of my enthusiasm for Calco-Mix.
